## DESCRIPTION
`librefetch` is a program to streamline creation of custom source
tarballs for `PKGBUILD(5)` files.
-To automatically use `librefetch` to download or create a source
-tarball, you can add `libre://FILENAME.tar.gz` to the source array in
-your `PKGBUILD`. This works because a post-install script for the
-package adds `librefetch` as a download agent for `libre://` to
-`makepkg.conf`. Because of this, it is almost never necessary to call
-`librefetch` manually.
+If a URL mentioned in the `source` array in a `PKGUILD` is in a
+location that Parabola uploads "custom" source tarballs (or configured
+locations), and no file is at that URL, librefetch will automatically
+create it for you.
-There are 6 modes:
+This works because a post-install script for the package configures
+`librefetch` as the download agent for `https://` URLs in
+`makepkg.conf`; allowing it to jump in and create a file if need be.
+Because of this, it is almost never necessary to call `librefetch`
+manually.
+
+The post-install script also configures `librefetch` as the download
+agent for `libre://` URLs, for compatability with PKGBUILDs that used
+a previous version of librefetch.
+
+There are 5 modes:
- * `download-create`: The default mode. First try `download` mode,
- then `create` mode.
* `download`: Download the tarball from the configured mirror.
* `create`: Create the tarball from a `PKGBUILD`/`SRCBUILD`.
* `checksums`: Generate integrity checks for source files.
* `print`: Print the effective build script.
* `help`: Print `librefetch` usage information.
+The normal mode of operation is `download` mode. If `download` mode
+fails, it may choose to try `create` mode.
