Committed this at the request of mjc. Apparently it's a patch managment

script to be used in conjuction with his mjc-sources package.

+# addpatches - a script to apply a kernel patch set.
+#
+# In a patch directory, the patches are organized with a numeric prefix:
+#    00_*
+#    01_*
+#    02_*
+#    ...
+#    99_*
+# They should be sortable by the wildcard expression '*_*'.
+#
+# Usage: addpatches [ patcharg [ sourcedir [ patchdir ] ] ]
+#     The source directory defaults to /usr/src/linux, and the patch
+#     directory defaults to the current directory
+#
+# addpatches determines the current kernel version from the top-level Makefile.
+# It then looks for patches for the next sublevel in the patch directory.
+# This is applied using "patch -p1 -s" from within the kernel directory.
+# A check is then made for "*.rej" files to see if the patch was
+# successful.  If it is, then all of the "*.orig" files are removed.
+#
+# Thanks to
+#       Nick Holloway <Nick.Holloway@alfie.demon.co.uk>
+#       Adam Sulmicki <adam@cfar.umd.edu>
+#       Dave Gilbert <linux@treblig.org>
+# for the scripts/patch-kernel script.

+# Set directories from arguments, or use defaults.
