The only tricky thing when building from Git is the weird dependence on the devtools-par source code. The build system will by default look at `$(topdir)/../devtools-par` for the devtools-par source code, and copy the relevant files into the libretools directory. This can be changed by adjusting the `devtoolsdir` configuration variable, see "Configuration" in the main INSTALL file. If the `$(devtoolsdir)` directory does not exist, but all of the copied files exist in the libretools directory, they will simply be used. The distribution tarball includes the copies of the devtools files, so it is not necessary to download the devtools source separately when using the tarball. Once you have the devtools source taken care of, you can build and install like normal.
