+Quick Guide To Patching This Package For The Impatient
+------------------------------------------------------
+
+1. Make sure you have quilt installed
+2. Unpack the package as usual with "dpkg-source -x"
+3. Run the "patch" target in debian/rules
+4. Create a new patch with "quilt new" (see quilt(1))
+5. Edit all the files you want to include in the patch with "quilt edit" 
+   (see quilt(1)).
+6. Write the patch with "quilt refresh" (see quilt(1))
+7. Run the "clean" target in debian/rules
+
+Alternatively, instead of using quilt directly, you can drop the patch in to 
+debian/patches and add the name of the patch to debian/patches/series.
+
+------------------------------------
+Guide To The X Strike Force Packages
+------------------------------------
+
+The X Strike Force team maintains X packages in git repositories on
+git.debian.org in the pkg-xorg subdirectory. Most upstream packages
+are actually maintained in git repositories as well, so they often
+just need to be pulled into git.debian.org in a "upstream-*" branch.
+Otherwise, the upstream sources are manually installed in the Debian
+git repository.
+
+The .orig.tar.gz upstream source file could be generated this
+"upstream-*" branch in the Debian git repository but it is actually
+copied from upstream tarballs directly.
+
+Due to X.org being highly modular, packaging all X.org applications
+as their own independent packages would have created too many Debian
+packages. For this reason, some X.org applications have been grouped
+into larger packages: xutils, xutils-dev, x11-apps, x11-session-utils,
+x11-utils, x11-xfs-utils, x11-xkb-utils, x11-xserver-utils.
+Most packages, including the X.org server itself and all libraries
+and drivers are, however maintained independently.
+
+The Debian packaging is added by creating the "debian-*" git branch
+which contains the aforementioned "upstream-*" branch plus the debian/
+repository files.
+When a patch has to be applied to the Debian package, two solutions
+are involved:
+* If the patch is available in one of the upstream branches, it
+  may be git'cherry-picked into the Debian repository. In this
+  case, it appears directly in the .diff.gz.
+* Otherwise, the patch is added to debian/patches/ which is managed
+  with quilt as documented in /usr/share/doc/quilt/README.source.
+
+quilt is actually invoked by the Debian X packaging through a larger
+set of scripts called XSFBS. XSFBS brings some other X specific
+features such as managing dependencies and conflicts due to the video
+and input driver ABIs.
+XSFBS itself is maintained in a separate repository at
+  git://git.debian.org/pkg-xorg/xsfbs.git
+and it is pulled inside the other Debian X repositories when needed.
+
+The XSFBS patching system requires a build dependency on quilt. Also
+a dependency on $(STAMP_DIR)/patch has to be added to debian/rules
+so that the XSFBS patching occurs before the actual build. So the
+very first target of the build (likely the one running autoreconf)
+should depend on $(STAMP_DIR)/patch. It should also not depend on
+anything so that parallel builds are correctly supported (nothing
+should probably run while patching is being done). And finally, the
+clean target should depend on the xsfclean target so that patches
+are unapplied on clean.
+
+When the upstream sources contain some DFSG-nonfree files, they are
+listed in text files in debian/prune/ in the "debian-*" branch of
+the Debian repository. XSFBS' scripts then take care of removing
+these listed files during the build so as to generate a modified
+DFSG-free .orig.tar.gz tarball.
