+Patches applied to the Debian version of GCC
+--------------------------------------------
+
+Debian specific patches can be found in the debian/patches directory.
+Quilt is used as the patch system. See /usr/share/doc/quilt/README.source
+for details about quilt.
+
+Patches are applied by calling `debian/rules patch'. The `series'
+file is constructed on the fly based on the files found in the to
+debian/rules.patch "debian_patches" variable, configure scripts are
+regenerated in the `patch' target. The gcc source is unpacked under
+src/ this needs to be reflected in the patch header.
+
+The source packages gcj-x.y and gnat-x.y do not contain copies of the
+source code but build-depend on the appropriate gcc-x.y-source package
+instead.
