+GPL VERSION 3
+
+
+
+
+ GNU GENERAL PUBLIC LICENSE
+ Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+ The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works. By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users. We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors. You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+ To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights. Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received. You must make sure that they, too, receive
+or can get the source code. And you must show them these terms so they
+know their rights.
+
+ Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+ For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software. For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+ Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so. This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software. The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable. Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products. If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+ Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary. To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ TERMS AND CONDITIONS
+
+ 0. Definitions.
+
+ "This License" refers to version 3 of the GNU General Public License.
+
+ "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+ "The Program" refers to any copyrightable work licensed under this
+License. Each licensee is addressed as "you". "Licensees" and
+"recipients" may be individuals or organizations.
+
+ To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy. The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+ A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+ To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy. Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+ To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies. Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+ An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License. If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+ 1. Source Code.
+
+ The "source code" for a work means the preferred form of the work
+for making modifications to it. "Object code" means any non-source
+form of a work.
+
+ A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+ The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form. A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+ The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities. However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work. For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+ The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+ The Corresponding Source for a work in source code form is that
+same work.
+
+ 2. Basic Permissions.
+
+ All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met. This License explicitly affirms your unlimited
+permission to run the unmodified Program. The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work. This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+ You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force. You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright. Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+ Conveying under any other circumstances is permitted solely under
+the conditions stated below. Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+ 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+ No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+ When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+ 4. Conveying Verbatim Copies.
+
+ You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+ You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+ 5. Conveying Modified Source Versions.
+
+ You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+ a) The work must carry prominent notices stating that you modified
+ it, and giving a relevant date.
+
+ b) The work must carry prominent notices stating that it is
+ released under this License and any conditions added under section
+ 7. This requirement modifies the requirement in section 4 to
+ "keep intact all notices".
+
+ c) You must license the entire work, as a whole, under this
+ License to anyone who comes into possession of a copy. This
+ License will therefore apply, along with any applicable section 7
+ additional terms, to the whole of the work, and all its parts,
+ regardless of how they are packaged. This License gives no
+ permission to license the work in any other way, but it does not
+ invalidate such permission if you have separately received it.
+
+ d) If the work has interactive user interfaces, each must display
+ Appropriate Legal Notices; however, if the Program has interactive
+ interfaces that do not display Appropriate Legal Notices, your
+ work need not make them do so.
+
+ A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit. Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+ 6. Conveying Non-Source Forms.
+
+ You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+ a) Convey the object code in, or embodied in, a physical product
+ (including a physical distribution medium), accompanied by the
+ Corresponding Source fixed on a durable physical medium
+ customarily used for software interchange.
+
+ b) Convey the object code in, or embodied in, a physical product
+ (including a physical distribution medium), accompanied by a
+ written offer, valid for at least three years and valid for as
+ long as you offer spare parts or customer support for that product
+ model, to give anyone who possesses the object code either (1) a
+ copy of the Corresponding Source for all the software in the
+ product that is covered by this License, on a durable physical
+ medium customarily used for software interchange, for a price no
+ more than your reasonable cost of physically performing this
+ conveying of source, or (2) access to copy the
+ Corresponding Source from a network server at no charge.
+
+ c) Convey individual copies of the object code with a copy of the
+ written offer to provide the Corresponding Source. This
+ alternative is allowed only occasionally and noncommercially, and
+ only if you received the object code with such an offer, in accord
+ with subsection 6b.
+
+ d) Convey the object code by offering access from a designated
+ place (gratis or for a charge), and offer equivalent access to the
+ Corresponding Source in the same way through the same place at no
+ further charge. You need not require recipients to copy the
+ Corresponding Source along with the object code. If the place to
+ copy the object code is a network server, the Corresponding Source
+ may be on a different server (operated by you or a third party)
+ that supports equivalent copying facilities, provided you maintain
+ clear directions next to the object code saying where to find the
+ Corresponding Source. Regardless of what server hosts the
+ Corresponding Source, you remain obligated to ensure that it is
+ available for as long as needed to satisfy these requirements.
+
+ e) Convey the object code using peer-to-peer transmission, provided
+ you inform other peers where the object code and Corresponding
+ Source of the work are being offered to the general public at no
+ charge under subsection 6d.
+
+ A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+ A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling. In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage. For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product. A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+ "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source. The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+ If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information. But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+ The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed. Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+ Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+ 7. Additional Terms.
+
+ "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law. If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+ When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it. (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.) You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+ Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+ a) Disclaiming warranty or limiting liability differently from the
+ terms of sections 15 and 16 of this License; or
+
+ b) Requiring preservation of specified reasonable legal notices or
+ author attributions in that material or in the Appropriate Legal
+ Notices displayed by works containing it; or
+
+ c) Prohibiting misrepresentation of the origin of that material, or
+ requiring that modified versions of such material be marked in
+ reasonable ways as different from the original version; or
+
+ d) Limiting the use for publicity purposes of names of licensors or
+ authors of the material; or
+
+ e) Declining to grant rights under trademark law for use of some
+ trade names, trademarks, or service marks; or
+
+ f) Requiring indemnification of licensors and authors of that
+ material by anyone who conveys the material (or modified versions of
+ it) with contractual assumptions of liability to the recipient, for
+ any liability that these contractual assumptions directly impose on
+ those licensors and authors.
+
+ All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10. If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term. If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+ If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+ Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+ 8. Termination.
+
+ You may not propagate or modify a covered work except as expressly
+provided under this License. Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+ However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+ Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+ Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License. If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+ 9. Acceptance Not Required for Having Copies.
+
+ You are not required to accept this License in order to receive or
+run a copy of the Program. Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance. However,
+nothing other than this License grants you permission to propagate or
+modify any covered work. These actions infringe copyright if you do
+not accept this License. Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+ 10. Automatic Licensing of Downstream Recipients.
+
+ Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License. You are not responsible
+for enforcing compliance by third parties with this License.
+
+ An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations. If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+ You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License. For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+ 11. Patents.
+
+ A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based. The
+work thus licensed is called the contributor's "contributor version".
+
+ A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version. For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+ Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+ In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement). To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+ If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients. "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+ If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+ A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License. You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+ Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+ 12. No Surrender of Others' Freedom.
+
+ If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all. For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+ 13. Use with the GNU Affero General Public License.
+
+ Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work. The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+ 14. Revised Versions of this License.
+
+ The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+ Each version is given a distinguishing version number. If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation. If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+ If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+ Later license versions may give you additional or different
+permissions. However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+ 15. Disclaimer of Warranty.
+
+ THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+ 16. Limitation of Liability.
+
+ IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+ 17. Interpretation of Sections 15 and 16.
+
+ If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.

+# lessphp v0.5.0
+### <http://leafo.net/lessphp>
+
+`lessphp` is a compiler for LESS written in PHP. The documentation is great,
+so check it out: <http://leafo.net/lessphp/docs/>.
+
+Here's a quick tutorial:
+
+### How to use in your PHP project
+
+The only file required is `lessc.inc.php`, so copy that to your include directory.
+
+The typical flow of **lessphp** is to create a new instance of `lessc`,
+configure it how you like, then tell it to compile something using one built in
+compile methods.
+
+The `compile` method compiles a string of LESS code to CSS.
+
+```php
+<?php
+require "lessc.inc.php";
+
+$less = new lessc;
+echo $less->compile(".block { padding: 3 + 4px }");
+```
+
+The `compileFile` method reads and compiles a file. It will either return the
+result or write it to the path specified by an optional second argument.
+
+```php
+<?php
+echo $less->compileFile("input.less");
+```
+
+The `compileChecked` method is like `compileFile`, but it only compiles if the output
+file doesn't exist or it's older than the input file:
+
+```php
+<?php
+$less->checkedCompile("input.less", "output.css");
+```
+
+If there any problem compiling your code, an exception is thrown with a helpful message:
+
+```php
+<?php
+try {
+ $less->compile("invalid LESS } {");
+} catch (exception $e) {
+ echo "fatal error: " . $e->getMessage();
+}
+```
+
+The `lessc` object can be configured through an assortment of instance methods.
+Some possible configuration options include [changing the output format][1],
+[setting variables from PHP][2], and [controlling the preservation of
+comments][3], writing [custom functions][4] and much more. It's all described
+in [the documentation][0].
+
+
+ [0]: http://leafo.net/lessphp/docs/
+ [1]: http://leafo.net/lessphp/docs/#output_formatting
+ [2]: http://leafo.net/lessphp/docs/#setting_variables_from_php
+ [3]: http://leafo.net/lessphp/docs/#preserving_comments
+ [4]: http://leafo.net/lessphp/docs/#custom_functions
+
+
+### How to use from the command line
+
+An additional script has been included to use the compiler from the command
+line. In the simplest invocation, you specify an input file and the compiled
+css is written to standard out:
+
+ $ plessc input.less > output.css
+
+Using the -r flag, you can specify LESS code directly as an argument or, if
+the argument is left off, from standard in:
+
+ $ plessc -r "my less code here"
+
+Finally, by using the -w flag you can watch a specified input file and have it
+compile as needed to the output file:
+
+ $ plessc -w input-file output-file
+
+Errors from watch mode are written to standard out.
+
+The -f flag sets the [output formatter][1]. For example, to compress the
+output run this:
+
+ $ plessc -f=compressed myfile.less
+
+For more help, run `plessc --help`

+<div style="margin-bottom: 1em;">$index</div>
+
+**lessphp** is a compiler that generates CSS from a superset language which
+adds a collection of convenient features often seen in other languages. All CSS
+is compatible with LESS, so you can start using new features with your existing CSS.
+
+It is designed to be compatible with [less.js](http://lesscss.org), and suitable
+as a drop in replacement for PHP projects.
+
+## Getting Started
+
+The homepage for **lessphp** can be found at [http://leafo.net/lessphp/][1].
+
+You can follow development at the project's [GitHub][2].
+
+Including **lessphp** in your project is as simple as dropping the single
+include file into your code base and running the appropriate compile method as
+described in the [PHP Interface](#php_interface).
+
+ [1]: http://leafo.net/lessphp "lessphp homepage"
+ [2]: https://github.com/leafo/lessphp "lessphp GitHub page"
+
+## Installation
+
+**lessphp** is distributed entirely in a single stand-alone file. Download the
+latest version from either [the homepage][1] or [GitHub][2].
+
+Development versions can also be downloading from GitHub.
+
+Place `lessphp.inc.php` in a location available to your PHP scripts, and
+include it. That's it! you're ready to begin.
+
+## The Language
+
+**lessphp** is very easy to learn because it generally functions how you would
+expect it to. If you feel something is challenging or missing, feel free to
+open an issue on the [bug tracker](https://github.com/leafo/lessphp/issues).
+
+It is also easy to learn because any standards-compliant CSS code is valid LESS
+code. You are free to gradually enhance your existing CSS code base with LESS
+features without having to worry about rewriting anything.
+
+The following is a description of the new languages features provided by LESS.
+
+### Line Comments
+
+Simple but very useful; line comments are started with `//`:
+
+ ```less
+ // this is a comment
+ body {
+ color: red; // as is this
+ /* block comments still work also */
+ }
+ ```
+
+### Variables
+
+Variables are identified with a name that starts with `@`. To declare a
+variable, you create an appropriately named CSS property and assign it a value:
+
+ ```less
+ @family: "verdana";
+ @color: red;
+ body {
+ @mycolor: red;
+ font-family: @family;
+ color: @color;
+ border-bottom: 1px solid @color;
+ }
+ ```
+
+Variable declarations will not appear in the output. Variables can be declared
+in the outer most scope of the file, or anywhere else a CSS property may
+appear. They can hold any CSS property value.
+
+Variables are only visible for use from their current scope, or any enclosed
+scopes.
+
+If you have a string or keyword in a variable, you can reference another
+variable by that name by repeating the `@`:
+
+ ```less
+ @value: 20px;
+ @value_name: "value";
+
+ width: @@value_name;
+ ```
+
+### Expressions
+
+Expressions let you combine values and variables in meaningful ways. For
+example you can add to a color to make it a different shade. Or divide up the
+width of your layout logically. You can even concatenate strings.
+
+Use the mathematical operators to evaluate an expression:
+
+ ```less
+ @width: 960px;
+ .nav {
+ width: @width / 3;
+ color: #001 + #abc;
+ }
+ .body {
+ width: 2 * @width / 3;
+ font-family: "hel" + "vetica";
+ }
+ ```
+
+Parentheses can be used to control the order of evaluation. They can also be
+used to force an evaluation for cases where CSS's syntax makes the expression
+ambiguous.
+
+The following property will produce two numbers, instead of doing the
+subtraction:
+
+ ```less
+ margin: 10px -5px;
+ ```
+
+To force the subtraction:
+
+ ```less
+ margin: (10px -5px);
+ ```
+
+It is also safe to surround mathematical operators by spaces to ensure that
+they are evaluated:
+
+ ```less
+ margin: 10px - 5px;
+ ```
+
+Division has a special quirk. There are certain CSS properties that use the `/`
+operator as part of their value's syntax. Namely, the [font][4] shorthand and
+[border-radius][3].
+
+ [3]: https://developer.mozilla.org/en/CSS/border-radius
+ [4]: https://developer.mozilla.org/en/CSS/font
+
+
+Thus, **lessphp** will ignore any division in these properties unless it is
+wrapped in parentheses. For example, no division will take place here:
+
+ ```less
+ .font {
+ font: 20px/80px "Times New Roman";
+ }
+ ```
+
+In order to force division we must wrap the expression in parentheses:
+
+ ```less
+ .font {
+ font: (20px/80px) "Times New Roman";
+ }
+ ```
+
+If you want to write a literal `/` expression without dividing in another
+property (or a variable), you can use [string unquoting](#string_unquoting):
+
+ ```less
+ .var {
+ @size: ~"20px/80px";
+ font: @size sans-serif;
+ }
+ ```
+
+### Nested Blocks
+
+By nesting blocks we can build up a chain of CSS selectors through scope
+instead of repeating them. In addition to reducing repetition, this also helps
+logically organize the structure of our CSS.
+
+ ```less
+ ol.list {
+ li.special {
+ border: 1px solid red;
+ }
+
+ li.plain {
+ font-weight: bold;
+ }
+ }
+ ```
+
+
+This will produce two blocks, a `ol.list li.special` and `ol.list li.plain`.
+
+Blocks can be nested as deep as required in order to build a hierarchy of
+relationships.
+
+The `&` operator can be used in a selector to represent its parent's selector.
+If the `&` operator is used, then the default action of appending the parent to
+the front of the child selector separated by space is not performed.
+
+ ```less
+ b {
+ a & {
+ color: red;
+ }
+
+ // the following have the same effect
+
+ & i {
+ color: blue;
+ }
+
+ i {
+ color: blue;
+ }
+ }
+ ```
+
+
+Because the `&` operator respects the whitespace around it, we can use it to
+control how the child blocks are joined. Consider the differences between the
+following:
+
+ ```less
+ div {
+ .child-class { color: purple; }
+
+ &.isa-class { color: green; }
+
+ #child-id { height: 200px; }
+
+ &#div-id { height: 400px; }
+
+ &:hover { color: red; }
+
+ :link { color: blue; }
+ }
+ ```
+
+The `&` operator also works with [mixins](#mixins), which produces interesting results:
+
+ ```less
+ .within_box_style() {
+ .box & {
+ color: blue;
+ }
+ }
+
+ #menu {
+ .within_box_style;
+ }
+ ```
+
+### Mixins
+
+Any block can be mixed in just by naming it:
+
+ ```less
+ .mymixin {
+ color: blue;
+ border: 1px solid red;
+
+ .special {
+ font-weight: bold;
+ }
+ }
+
+
+ h1 {
+ font-size: 200px;
+ .mymixin;
+ }
+ ```
+
+All properties and child blocks are mixed in.
+
+Mixins can be made parametric, meaning they can take arguments, in order to
+enhance their utility. A parametric mixin all by itself is not outputted when
+compiled. Its properties will only appear when mixed into another block.
+
+The canonical example is to create a rounded corners mixin that works across
+browsers:
+
+ ```less
+ .rounded-corners(@radius: 5px) {
+ border-radius: @radius;
+ -webkit-border-radius: @radius;
+ -moz-border-radius: @radius;
+ }
+
+ .header {
+ .rounded-corners();
+ }
+
+ .info {
+ background: red;
+ .rounded-corners(14px);
+ }
+ ```
+
+If you have a mixin that doesn't have any arguments, but you don't want it to
+show up in the output, give it a blank argument list:
+
+ ```less
+ .secret() {
+ font-size: 6000px;
+ }
+
+ .div {
+ .secret;
+ }
+ ```
+
+If the mixin doesn't need any arguments, you can leave off the parentheses when
+mixing it in, as seen above.
+
+You can also mixin a block that is nested inside other blocks. You can think of
+the outer block as a way of making a scope for your mixins. You just list the
+names of the mixins separated by spaces, which describes the path to the mixin
+you want to include. Optionally you can separate them by `>`.
+
+ ```less
+ .my_scope {
+ .some_color {
+ color: red;
+ .inner_block {
+ text-decoration: underline;
+ }
+ }
+ .bold {
+ font-weight: bold;
+ color: blue;
+ }
+ }
+
+ .a_block {
+ .my_scope .some_color;
+ .my_scope .some_color .inner_block;
+ }
+
+ .another_block {
+ // the alternative syntax
+ .my_scope > .bold;
+ }
+ ```
+
+
+#### Mixin Arguments
+
+When declaring a mixin you can specify default values for each argument. Any
+argument left out will be given the default value specified. Here's the
+syntax:
+
+```less
+.mix(@color: red, @height: 20px, @pad: 12px) {
+ border: 1px solid @color;
+ height: @height - @pad;
+ padding: @pad;
+}
+
+.default1 {
+ .mix();
+}
+
+.default2 {
+ .mix(blue);
+}
+
+.default3 {
+ .mix(blue, 40px, 5px);
+}
+```
+
+Additionally, you can also call a mixin using the argument names, this is
+useful if you want to replace a specific argument while having all the others
+take the default regardless of what position the argument appears in. The
+syntax looks something like this:
+
+
+```lessbasic
+div {
+ .my_mixin(@paddding: 4px); // @color and @height get default values
+ .my_mixin(@paddding: 4px, @height: 50px); // you can specify them in any order
+}
+```
+
+You can also combine the ordered arguments with the named ones:
+
+```lessbasic
+div {
+ // @color is blue, @padding is 4px, @height is default
+ .my_mixin(blue, @padding: 4px);
+}
+```
+
+Mixin arguments can be delimited with either a `,` or `;`, but only one can be
+active at once. This means that each argument is separated by either `,` or
+`;`. By default `,` is the delimiter, in all the above examples we used a `,`.
+
+A problem arises though, sometimes CSS value lists are made up with commas. In
+order to be able to pass a comma separated list literal we need to use `;` as
+the delimiter. (You don't need to worry about this if your list is stored in a
+variable)
+
+If a `;` appears anywhere in the argument list, then it will be used as the
+argument delimiter, and all commas we be used as part of the argument values.
+
+Here's a basic example:
+
+```less
+.fancy_mixin(@box_shadow, @color: blue) {
+ border: 1px solid @color;
+ box-shadow: @box_shadow;
+}
+
+
+div {
+ // two arguments passed separated by ;
+ .fancy_mixin(2px 2px, -2px -2px; red);
+}
+
+pre {
+ // one argument passed, ends in ;
+ .fancy_mixin(inset 4px 4px, -2px 2px;);
+}
+
+```
+
+If we only want to pass a single comma separated value we still need to use
+`;`, to do this we stick it on the end as demonstrated above.
+
+
+#### `@arguments` Variable
+
+Within an mixin there is a special variable named `@arguments` that contains
+all the arguments passed to the mixin along with any remaining arguments that
+have default values. The value of the variable has all the values separated by
+spaces.
+
+This useful for quickly assigning all the arguments:
+
+ ```less
+ .box-shadow(@x, @y, @blur, @color) {
+ box-shadow: @arguments;
+ -webkit-box-shadow: @arguments;
+ -moz-box-shadow: @arguments;
+ }
+ .menu {
+ .box-shadow(1px, 1px, 5px, #aaa);
+ }
+ ```
+
+In addition to the arguments passed to the mixin, `@arguments` will also include
+remaining default values assigned by the mixin:
+
+
+ ```less
+ .border-mixin(@width, @style: solid, @color: black) {
+ border: @arguments;
+ }
+
+ pre {
+ .border-mixin(4px, dotted);
+ }
+
+ ```
+
+
+#### Pattern Matching
+
+When you *mix in* a mixin, all the available mixins of that name in the current
+scope are checked to see if they match based on what was passed to the mixin
+and how it was declared.
+
+The simplest case is matching by number of arguments. Only the mixins that
+match the number of arguments passed in are used.
+
+ ```less
+ .simple() { // matches no arguments
+ height: 10px;
+ }
+
+ .simple(@a, @b) { // matches two arguments
+ color: red;
+ }
+
+ .simple(@a) { // matches one argument
+ color: blue;
+ }
+
+ div {
+ .simple(10);
+ }
+
+ span {
+ .simple(10, 20);
+ }
+ ```
+
+Whether an argument has default values is also taken into account when matching
+based on number of arguments:
+
+ ```less
+ // matches one or two arguments
+ .hello(@a, @b: blue) {
+ height: @a;
+ color: @b;
+ }
+
+ .hello(@a, @b) { // matches only two
+ width: @a;
+ border-color: @b;
+ }
+
+ .hello(@a) { // matches only one
+ padding: 1em;
+ }
+
+ div {
+ .hello(10px);
+ }
+
+ pre {
+ .hello(10px, yellow);
+ }
+ ```
+
+Additionally, a *vararg* value can be used to further control how things are
+matched. A mixin's argument list can optionally end in the special argument
+named `...`. The `...` may match any number of arguments, including 0.
+
+ ```less
+ // this will match any number of arguments
+ .first(...) {
+ color: blue;
+ }
+
+ // matches at least 1 argument
+ .second(@arg, ...) {
+ height: 200px + @arg;
+ }
+
+ div { .first("some", "args"); }
+ pre { .second(10px); }
+ ```
+
+If you want to capture the values that get captured by the *vararg* you can
+give it a variable name by putting it directly before the `...`. This variable
+must be the last argument defined. It's value is just like the special
+[`@arguments` variable](#arguments_variable), a space separated list.
+
+
+ ```less
+ .hello(@first, @rest...) {
+ color: @first;
+ text-shadow: @rest;
+ }
+
+ span {
+ .hello(red, 1px, 1px, 0px, white);
+ }
+
+ ```
+
+Another way of controlling whether a mixin matches is by specifying a value in
+place of an argument name when declaring the mixin:
+
+ ```less
+ .style(old, @size) {
+ font: @size serif;
+ }
+
+ .style(new, @size) {
+ font: @size sans-serif;
+ }
+
+ .style(@_, @size) {
+ letter-spacing: floor(@size / 6px);
+ }
+
+ em {
+ @switch: old;
+ .style(@switch, 15px);
+ }
+ ```
+
+Notice that two of the three mixins were matched. The mixin with a matching
+first argument, and the generic mixin that matches two arguments. It's common
+to use `@_` as the name of a variable we intend to not use. It has no special
+meaning to LESS, just to the reader of the code.
+
+#### Guards
+
+Another way of restricting when a mixin is mixed in is by using guards. A guard
+is a special expression that is associated with a mixin declaration that is
+evaluated during the mixin process. It must evaluate to true before the mixin
+can be used.
+
+We use the `when` keyword to begin describing a list of guard expressions.
+
+Here's a simple example:
+
+ ```less
+ .guarded(@arg) when (@arg = hello) {
+ color: blue;
+ }
+
+ div {
+ .guarded(hello); // match
+ }
+
+ span {
+ .guarded(world); // no match
+ }
+ ```
+Only the `div`'s mixin will match in this case, because the guard expression
+requires that `@arg` is equal to `hello`.
+
+We can include many different guard expressions by separating them by commas.
+Only one of them needs to match to trigger the mixin:
+
+ ```less
+ .x(@a, @b) when (@a = hello), (@b = world) {
+ width: 960px;
+ }
+
+ div {
+ .x(hello, bar); // match
+ }
+
+ span {
+ .x(foo, world); // match
+ }
+
+ pre {
+ .x(foo, bar); // no match
+ }
+ ```
+
+Instead of a comma, we can use `and` keyword to make it so all of the guards
+must match in order to trigger the mixin. `and` has higher precedence than the
+comma.
+
+ ```less
+ .y(@a, @b) when (@a = hello) and (@b = world) {
+ height: 600px;
+ }
+
+ div {
+ .y(hello, world); // match
+ }
+
+ span {
+ .y(hello, bar); // no match
+ }
+ ```
+
+Commas and `and`s can be mixed and matched.
+
+You can also negate a guard expression by using `not` in from of the parentheses:
+
+ ```less
+ .x(@a) when not (@a = hello) {
+ color: blue;
+ }
+
+ div {
+ .x(hello); // no match
+ }
+ ```
+
+The `=` operator is used to check equality between any two values. For numbers
+the following comparison operators are also defined:
+
+`<`, `>`, `=<`, `>=`
+
+There is also a collection of predicate functions that can be used to test the
+type of a value.
+
+These are `isnumber`, `iscolor`, `iskeyword`, `isstring`, `ispixel`,
+`ispercentage` and `isem`.
+
+ ```less
+ .mix(@a) when (ispercentage(@a)) {
+ height: 500px * @a;
+ }
+ .mix(@a) when (ispixel(@a)) {
+ height: @a;
+ }
+
+ div.a {
+ .mix(50%);
+ }
+
+ div.a {
+ .mix(350px);
+ }
+ ```
+
+#### !important
+
+If you want to apply the `!important` suffix to every property when mixing in a
+mixin, just append `!important` to the end of the call to the mixin:
+
+ ```less
+ .make_bright {
+ color: red;
+ font-weight: bold;
+ }
+
+ .color {
+ color: green;
+ }
+
+ body {
+ .make_bright() !important;
+ .color();
+ }
+
+ ```
+
+### Selector Expressions
+
+Sometimes we want to dynamically generate the selector of a block based on some
+variable or expression. We can do this by using *selector expressions*. Selector
+expressions are CSS selectors that are evaluated in the current scope before
+being written out.
+
+A simple example is a mixin that dynamically creates a selector named after the
+mixin's argument:
+
+ ```less
+ .create-selector(@name) {
+ @{name} {
+ color: red;
+ }
+ }
+
+ .create-selector(hello);
+ .create-selector(world);
+ ```
+
+The string interpolation syntax works inside of selectors, letting you insert varaibles.
+
+Here's an interesting example adapted from Twitter Bootstrap. A couple advanced
+things are going on. We are using [Guards](#guards) along with a recursive
+mixin to work like a loop to generate a series of CSS blocks.
+
+
+ ```less
+ // create our recursive mixin:
+ .spanX (@index) when (@index > 0) {
+ .span@{index} {
+ width: @index * 100px;
+ }
+ .spanX(@index - 1);
+ }
+ .spanX (0) {}
+
+ // mix it into the global scopee:
+ .spanX(4);
+ ```
+
+### Import
+
+Multiple LESS files can be compiled into a single CSS file by using the
+`@import` statement. Be careful, the LESS import statement shares syntax with
+the CSS import statement. If the file being imported ends in a `.less`
+extension, or no extension, then it is treated as a LESS import. Otherwise it
+is left alone and outputted directly:
+
+ ```lessbasic
+ // my_file.less
+ .some-mixin(@height) {
+ height: @height;
+ }
+
+ // main.less
+ @import "main.less" // will import the file if it can be found
+ @import "main.css" // will be left alone
+
+ body {
+ .some-mixin(400px);
+ }
+ ```
+
+All of the following lines are valid ways to import the same file:
+
+ ```lessbasic
+ @import "file";
+ @import 'file.less';
+ @import url("file");
+ @import url('file');
+ @import url(file);
+ ```
+
+When importing, the `importDir` is searched for files. This can be configured,
+see [PHP Interface](#php_interface).
+
+A file is only imported once. If you try to include the same file multiple
+times all the import statements after the first produce no output.
+
+### String Interpolation
+
+String interpolation is a convenient way to insert the value of a variable
+right into a string literal. Given some variable named `@var_name`, you just
+need to write it as `@{var_name}` from within the string to have its value
+inserted:
+
+ ```less
+ @symbol: ">";
+ h1:before {
+ content: "@{symbol}: ";
+ }
+
+ h2:before {
+ content: "@{symbol}@{symbol}: ";
+ }
+ ```
+
+There are two kinds of strings, implicit and explicit strings. Explicit strings
+are wrapped by double quotes, `"hello I am a string"`, or single quotes `'I am
+another string'`. Implicit strings only appear when using `url()`. The text
+between the parentheses is considered a string and thus string interpolation is
+possible:
+
+ ```less
+ @path: "files/";
+ body {
+ background: url(@{path}my_background.png);
+ }
+ ```
+
+### String Format Function
+
+The `%` function can be used to insert values into strings using a *format
+string*. It works similar to `printf` seen in other languages. It has the
+same purpose as string interpolation above, but gives explicit control over
+the output format.
+
+ ```less
+ @symbol: ">";
+ h1:before {
+ content: %("%s: ", @symbol);
+ }
+ ```
+
+The `%` function takes as its first argument the format string, following any
+number of addition arguments that are inserted in place of the format
+directives.
+
+A format directive starts with a `%` and is followed by a single character that
+is either `a`, `d`, or `s`:
+
+ ```less
+ strings: %("%a %d %s %a", hi, 1, 'ok', 'cool');
+ ```
+
+`%a` and `%d` format the value the same way: they compile the argument to its
+CSS value and insert it directly. When used with a string, the quotes are
+included in the output. This typically isn't what we want, so we have the `%s`
+format directive which strips quotes from strings before inserting them.
+
+The `%d` directive functions the same as `%a`, but is typically used for numbers
+assuming the output format of numbers might change in the future.
+
+### String Unquoting
+
+Sometimes you will need to write proprietary CSS syntax that is unable to be
+parsed. As a workaround you can place the code into a string and unquote it.
+Unquoting is the process of outputting a string without its surrounding quotes.
+There are two ways to unquote a string.
+
+The `~` operator in front of a string will unquote that string:
+
+ ```less
+ .class {
+ // a made up, but problematic vendor specific CSS
+ filter: ~"Microsoft.AlphaImage(src='image.png')";
+ }
+ ```
+
+If you are working with other types, such as variables, there is a built in
+function that let's you unquote any value. It is called `e`.
+
+ ```less
+ @color: "red";
+ .class {
+ color: e(@color);
+ }
+ ```
+
+### Built In Functions
+
+**lessphp** has a collection of built in functions:
+
+* `e(str)` -- returns a string without the surrounding quotes.
+ See [String Unquoting](#string_unquoting)
+
+* `floor(number)` -- returns the floor of a numerical input
+* `round(number, [precision])` -- returns the rounded value of numerical input with optional precision
+
+* `lighten(color, percent)` -- lightens `color` by `percent` and returns it
+* `darken(color, percent)` -- darkens `color` by `percent` and returns it
+
+* `saturate(color, percent)` -- saturates `color` by `percent` and returns it
+* `desaturate(color, percent)` -- desaturates `color` by `percent` and returns it
+
+* `fadein(color, percent)` -- makes `color` less transparent by `percent` and returns it
+* `fadeout(color, percent)` -- makes `color` more transparent by `percent` and returns it
+
+* `spin(color, amount)` -- returns a color with `amount` degrees added to hue
+
+* `fade(color, amount)` -- returns a color with the alpha set to `amount`
+
+* `hue(color)` -- returns the hue of `color`
+
+* `saturation(color)` -- returns the saturation of `color`
+
+* `lightness(color)` -- returns the lightness of `color`
+
+* `alpha(color)` -- returns the alpha value of `color` or 1.0 if it doesn't have an alpha
+
+* `percentage(number)` -- converts a floating point number to a percentage, e.g. `0.65` -> `65%`
+
+* `mix(color1, color1, percent)` -- mixes two colors by percentage where 100%
+ keeps all of `color1`, and 0% keeps all of `color2`. Will take into account
+ the alpha of the colors if it exists. See
+ <http://sass-lang.com/docs/yardoc/Sass/Script/Functions.html#mix-instance_method>.
+
+* `contrast(color, dark, light)` -- if `color` has a lightness value greater
+ than 50% then `dark` is returned, otherwise return `light`.
+
+* `extract(list, index)` -- returns the `index`th item from `list`. The list is
+ `1` indexed, meaning the first item's index is 1, the second is 2, and etc.
+
+* `pow(base, exp)` -- returns `base` raised to the power of `exp`
+
+* `pi()` -- returns pi
+
+* `mod(a,b)` -- returns `a` modulus `b`
+
+* `tan(a)` -- returns tangent of `a` where `a` is in radians
+
+* `cos(a)` -- returns cosine of `a` where `a` is in radians
+
+* `sin(a)` -- returns sine of `a` where `a` is in radians
+
+* `atan(a)` -- returns arc tangent of `a`
+
+* `acos(a)` -- returns arc cosine of `a`
+
+* `asin(a)` -- returns arc sine of `a`
+
+* `sqrt(a)` -- returns square root of `a`
+
+* `rgbahex(color)` -- returns a string containing 4 part hex color.
+
+ This is used to convert a CSS color into the hex format that IE's filter
+ method expects when working with an alpha component.
+
+ ```less
+ .class {
+ @start: rgbahex(rgba(25, 34, 23, .5));
+ @end: rgbahex(rgba(85, 74, 103, .6));
+ // abridged example
+ -ms-filter:
+ e("gradient(start=@{start},end=@{end})");
+ }
+ ```
+
+## PHP Interface
+
+When working with **lessphp** from PHP, the typical flow is to create a new
+instance of `lessc`, configure it how you like, then tell it to compile
+something using one built in compile methods.
+
+Methods:
+
+* [`compile($string)`](#compiling[) -- Compile a string
+
+* [`compileFile($inFile, [$outFile])`](#compiling) -- Compile a file to another or return it
+
+* [`checkedCompile($inFile, $outFile)`](#compiling) -- Compile a file only if it's newer
+
+* [`cachedCompile($cacheOrFile, [$force])`](#compiling_automatically) -- Conditionally compile while tracking imports
+
+* [`setFormatter($formatterName)`](#output_formatting) -- Change how CSS output looks
+
+* [`setPreserveComments($keepComments)`](#preserving_comments) -- Change if comments are kept in output
+
+* [`registerFunction($name, $callable)`](#custom_functions) -- Add a custom function
+
+* [`unregisterFunction($name)`](#custom_functions) -- Remove a registered function
+
+* [`setVariables($vars)`](#setting_variables_from_php) -- Set a variable from PHP
+
+* [`unsetVariable($name)`](#setting_variables_from_php) -- Remove a PHP variable
+
+* [`setImportDir($dirs)`](#import_directory) -- Set the search path for imports
+
+* [`addImportDir($dir)`](#import_directory) -- Append directory to search path for imports
+
+
+### Compiling
+
+The `compile` method compiles a string of LESS code to CSS.
+
+ ```php
+ <?php
+ require "lessc.inc.php";
+
+ $less = new lessc;
+ echo $less->compile(".block { padding: 3 + 4px }");
+ ```
+
+The `compileFile` method reads and compiles a file. It will either return the
+result or write it to the path specified by an optional second argument.
+
+ ```php
+ echo $less->compileFile("input.less");
+ ```
+
+The `compileChecked` method is like `compileFile`, but it only compiles if the output
+file doesn't exist or it's older than the input file:
+
+ ```php
+ $less->checkedCompile("input.less", "output.css");
+ ```
+
+See [Compiling Automatically](#compiling_automatically) for a description of
+the more advanced `cachedCompile` method.
+
+### Output Formatting
+
+Output formatting controls the indentation of the output CSS. Besides the
+default formatter, two additional ones are included and it's also easy to make
+your own.
+
+To use a formatter, the method `setFormatter` is used. Just
+pass the name of the formatter:
+
+ ```php
+ $less = new lessc;
+
+ $less->setFormatter("compressed");
+ echo $less->compile("div { color: lighten(blue, 10%) }");
+ ```
+
+In this example, the `compressed` formatter is used. The formatters are:
+
+ * `lessjs` *(default)* -- Same style used in LESS for JavaScript
+
+ * `compressed` -- Compresses all the unrequired whitespace
+
+ * `classic` -- **lessphp**'s original formatter
+
+To revert to the default formatter, call `setFormatter` with a value of `null`.
+
+#### Custom Formatter
+
+The easiest way to customize the formatter is to create your own instance of an
+existing formatter and alter its public properties before passing it off to
+**lessphp**. The `setFormatter` method can also take an instance of a
+formatter.
+
+Each of the formatter names corresponds to a class with `lessc_formatter_`
+prepended in front of it. Here the classic formatter is customized to use tabs
+instead of spaces:
+
+
+ ```php
+ $formatter = new lessc_formatter_classic;
+ $formatter->indentChar = "\t";
+
+ $less = new lessc;
+ $less->setFormatter($formatter);
+ echo $less->compileFile("myfile.less");
+ ```
+
+For more information about what can be configured with the formatter consult
+the source code.
+
+### Preserving Comments
+
+By default, all comments in the source LESS file are stripped when compiling.
+You might want to keep the `/* */` comments in the output though. For
+example, bundling a license in the file.
+
+Enable or disable comment preservation by calling `setPreserveComments`:
+
+ ```php
+ $less = new lessc;
+ $less->setPreserveComments(true);
+ echo $less->compile("/* hello! */");
+ ```
+
+Comments are disabled by default because there is additional overhead, and more
+often than not they aren't needed.
+
+
+### Compiling Automatically
+
+Often, you want to only compile a LESS file only if it has been modified since
+last compile. This is very important because compiling is performance intensive
+and you should avoid a recompile if it possible.
+
+The `checkedCompile` compile method will do just that. It will check if the
+input file is newer than the output file, or if the output file doesn't exist
+yet, and compile only then.
+
+ ```php
+ $less->checkedCompile("input.less", "output.css");
+ ```
+
+There's a problem though. `checkedCompile` is very basic, it only checks the
+input file's modification time. It is unaware of any files from `@import`.
+
+
+For this reason we also have `cachedCompile`. It's slightly more complex, but
+gives us the ability to check changes to all files including those imported. It
+takes one argument, either the name of the file we want to compile, or an
+existing *cache object*. Its return value is an updated cache object.
+
+If we don't have a cache object, then we call the function with the name of the
+file to get the initial cache object. If we do have a cache object, then we
+call the function with it. In both cases, an updated cache object is returned.
+
+The cache object keeps track of all the files that must be checked in order to
+determine if a rebuild is required.
+
+The cache object is a plain PHP `array`. It stores the last time it compiled in
+`$cache["updated"]` and output of the compile in `$cache["compiled"]`.
+
+Here we demonstrate creating an new cache object, then using it to see if we
+have a recompiled version available to be written:
+
+
+ ```php
+ $inputFile = "myfile.less";
+ $outputFile = "myfile.css";
+
+ $less = new lessc;
+
+ // create a new cache object, and compile
+ $cache = $less->cachedCompile($inputFile);
+
+ file_put_contents($outputFile, $cache["compiled"]);
+
+ // the next time we run, write only if it has updated
+ $last_updated = $cache["updated"];
+ $cache = $less->cachedCompile($cache);
+ if ($cache["updated"] > $last_updated) {
+ file_put_contents($outputFile, $cache["compiled"]);
+ }
+
+ ```
+
+In order for the system to fully work, we must save cache object between
+requests. Because it's a plain PHP `array`, it's sufficient to
+[`serialize`](http://php.net/serialize) it and save it the string somewhere
+like a file or in persistent memory.
+
+An example with saving cache object to a file:
+
+ ```php
+ function autoCompileLess($inputFile, $outputFile) {
+ // load the cache
+ $cacheFile = $inputFile.".cache";
+
+ if (file_exists($cacheFile)) {
+ $cache = unserialize(file_get_contents($cacheFile));
+ } else {
+ $cache = $inputFile;
+ }
+
+ $less = new lessc;
+ $newCache = $less->cachedCompile($cache);
+
+ if (!is_array($cache) || $newCache["updated"] > $cache["updated"]) {
+ file_put_contents($cacheFile, serialize($newCache));
+ file_put_contents($outputFile, $newCache['compiled']);
+ }
+ }
+
+ autoCompileLess('myfile.less', 'myfile.css');
+ ```
+
+`cachedCompile` method takes an optional second argument, `$force`. Passing in
+true will cause the input to always be recompiled.
+
+### Error Handling
+
+All of the compile methods will throw an `Exception` if the parsing fails or
+there is a compile time error. Compile time errors include things like passing
+incorrectly typed values for functions that expect specific things, like the
+color manipulation functions.
+
+ ```php
+ $less = new lessc;
+ try {
+ $less->compile("} invalid LESS }}}");
+ } catch (Exception $ex) {
+ echo "lessphp fatal error: ".$ex->getMessage();
+ }
+ ```
+### Setting Variables From PHP
+
+Before compiling any code you can set initial LESS variables from PHP. The
+`setVariables` method lets us do this. It takes an associative array of names
+to values. The values must be strings, and will be parsed into correct CSS
+values.
+
+
+ ```php
+ $less = new lessc;
+
+ $less->setVariables(array(
+ "color" => "red",
+ "base" => "960px"
+ ));
+
+ echo $less->compile(".magic { color: @color; width: @base - 200; }");
+ ```
+
+If you need to unset a variable, the `unsetVariable` method is available. It
+takes the name of the variable to unset.
+
+ ```php
+ $less->unsetVariable("color");
+ ```
+
+Be aware that the value of the variable is a string containing a CSS value. So
+if you want to pass a LESS string in, you're going to need two sets of quotes.
+One for PHP and one for LESS.
+
+
+ ```php
+ $less->setVariables(array(
+ "url" => "'http://example.com.com/'"
+ ));
+
+ echo $less->compile("body { background: url("@{url}/bg.png"); }");
+ ```
+
+### Import Directory
+
+When running the `@import` directive, an array of directories called the import
+search path is searched through to find the file being asked for.
+
+By default, when using `compile`, the import search path just contains `""`,
+which is equivalent to the current directory of the script. If `compileFile` is
+used, then the directory of the file being compiled is used as the starting
+import search path.
+
+Two methods are available for configuring the search path.
+
+`setImportDir` will overwrite the search path with its argument. If the value
+isn't an array it will be converted to one.
+
+
+In this example, `@import "colors";` will look for either
+`assets/less/colors.less` or `assets/bootstrap/colors.less` in that order:
+
+ ```php
+ $less->setImportDir(array("assets/less/", "assets/bootstrap"));
+
+ echo $less->compile('@import "colors";');
+ ```
+
+`addImportDir` will append a single path to the import search path instead of
+overwriting the whole thing.
+
+ ```php
+ $less->addImportDir("public/stylesheets");
+ ```
+
+### Custom Functions

+**lessphp** has a simple extension interface where you can implement user
+functions that will be exposed in LESS code during the compile. They can be a
+little tricky though because you need to work with the **lessphp** type system.
+
+The two methods we are interested in are `registerFunction` and
+`unregisterFunction`. `registerFunction` takes two arguments, a name and a
+callable value. `unregisterFunction` just takes the name of an existing
+function to remove.
+
+Here's an example that adds a function called `double` that doubles any numeric
+argument:
+
+ ```php
+ <?php
+ include "lessc.inc.php";
+
+ function lessphp_double($arg) {
+ list($type, $value) = $arg;
+ return array($type, $value*2);
+ }
+
+ $less = new lessc;
+ $less->registerFunction("double", "lessphp_double");
+
+ // gives us a width of 800px
+ echo $less->compile("div { width: double(400px); }");
+ ```
+
+The second argument to `registerFunction` is any *callable value* that is
+understood by [`call_user_func`](http://php.net/call_user_func).
+
+If we are using PHP 5.3 or above then we are free to pass a function literal
+like so:
+
+ ```php
+ $less->registerFunction("double", function($arg) {
+ list($type, $value, $unit) = $arg;
+ return array($type, $value*2, $unit);
+ });
+ ```
+
+Now let's talk about the `double` function itself.
+
+Although a little verbose, the implementation gives us some insight on the type
+system. All values in **lessphp** are stored in an array where the 0th element
+is a string representing the type, and the other elements make up the
+associated data for that value.
+
+The best way to get an understanding of the system is to register is dummy
+function which does a `var_dump` on the argument. Try passing the function
+different values from LESS and see what the results are.
+
+The return value of the registered function must also be a **lessphp** type,
+but if it is a string or numeric value, it will automatically be coerced into
+an appropriate typed value. In our example, we reconstruct the value with our
+modifications while making sure that we preserve the original type.
+
+The instance of **lessphp** itself is sent to the registered function as the
+second argument in addition to the arguments array.
+
+## Command Line Interface
+
+**lessphp** comes with a command line script written in PHP that can be used to
+invoke the compiler from the terminal. On Linux and OSX, all you need to do is
+place `plessc` and `lessc.inc.php` somewhere in your PATH (or you can run it in
+the current directory as well). On windows you'll need a copy of `php.exe` to
+run the file. To compile a file, `input.less` to CSS, run:
+
+ ```bash
+ $ plessc input.less
+ ```
+
+To write to a file, redirect standard out:
+
+ ```bash
+ $ plessc input.less > output.css
+ ```
+
+To compile code directly on the command line:
+
+ ```bash
+ $ plessc -r "@color: red; body { color: @color; }"
+ ```
+
+To watch a file for changes, and compile it as needed, use the `-w` flag:
+
+ ```bash
+ $ plessc -w input-file output-file
+ ```
+
+Errors from watch mode are written to standard out.

+/**
+ * The LESS compiler and parser.
+ *
+ * Converting LESS to CSS is a three stage process. The incoming file is parsed
+ * by `lessc_parser` into a syntax tree, then it is compiled into another tree
+ * representing the CSS structure by `lessc`. The CSS tree is fed into a
+ * formatter, like `lessc_formatter` which then outputs CSS as a string.
+ *
+ * During the first compile, all values are *reduced*, which means that their
+ * types are brought to the lowest form before being dump as strings. This
+ * handles math equations, variable dereferences, and the like.
+ *
+ * The `parse` function of `lessc` is the entry point.
+ *
+ * In summary:
+ *
+ * The `lessc` class creates an instance of the parser, feeds it LESS code,
+ * then transforms the resulting tree to a CSS tree. This class also holds the
+ * evaluation context, such as all available mixins and variables at any given
+ * time.
+ *
+ * The `lessc_parser` class is only concerned with parsing its input.
+ *
+ * The `lessc_formatter` takes a CSS tree, and dumps it to a formatted string,
+ * handling things like indentation.

+ * This parser is most similar to a recursive descent parser. Single
+ * functions represent discrete grammatical rules for the language, and
+ * they are able to capture the text that represents those rules.
+ *
+ * Consider the function lessc::keyword(). (all parse functions are
+ * structured the same)
+ *
+ * The function takes a single reference argument. When calling the
+ * function it will attempt to match a keyword on the head of the buffer.
+ * If it is successful, it will place the keyword in the referenced
+ * argument, advance the position in the buffer, and return true. If it
+ * fails then it won't advance the buffer and it will return false.
+ *
+ * All of these parse functions are powered by lessc::match(), which behaves
+ * the same way, but takes a literal regular expression. Sometimes it is
+ * more convenient to use match instead of creating a new function.
+ *
+ * Because of the format of the functions, to parse an entire string of
+ * grammatical rules, you can chain them together using &&.
+ *
+ * But, if some of the rules in the chain succeed before one fails, then
+ * the buffer position will be left at an invalid state. In order to
+ * avoid this, lessc::seek() is used to remember and set buffer positions.
+ *
+ * Before parsing a chain, use $s = $this->seek() to remember the current
+ * position into $s. Then if a chain fails, use $this->seek($s) to
+ * go back where we started.

+lessphp uses [phpunit](https://github.com/sebastianbergmann/phpunit/) for its tests
+
+* `InputTest.php` iterates through all the less files in `inputs/`, compiles
+ them, then compares the result with the respective file in `outputs/`.
+
+* `ApiTest.php` tests the behavior of lessphp's public API methods.
+
+* `ErrorHandlingTest.php` tests that lessphp throws appropriate errors when
+ given invalid LESS as input.
+
+From the root you can run `make` to run all the tests.
+
+## lessjs tests
+
+Tests found in `inputs_lessjs` are extracted directly from
+[less.js](https://github.com/less/less.js). The following license applies to
+those tests: https://github.com/less/less.js/blob/master/LICENSE
