-The program "xa-download-more" can be used to download more
-extensions from 3rd parties into the source tree. The URLs are listed
-in the "sources" file. If the "sources" file contains an entry like
-
-	http://foobar.org/xa/
-
-xa-download-more will inspect http://foobar.org/xa/xa-index.txt for
-files to download. That file may contain
-
-	foobar.tar.bz2
-
-and xa-download-more will then retrieve and unpack
-http://foobar.org/xa/foobar.tar.bz2.
-
-Files that should be contained in the tarball are an mconfig and
-Kbuild files to control building the extension, libxt_foobar.c for
-the userspace extension and xt_foobar.c for the kernel extension.
