+# Script to apply kernel patches.
+#   usage: patch-kernel [ sourcedir [ patchdir [ stopversion ] ] ]
+#     The source directory defaults to /usr/src/linux, and the patch
+#     directory defaults to the current directory.
+#
+# It 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.
+#

+# Added support for handling multiple types of compression. What includes
+# gzip, bzip, bzip2, zip, compress, and plaintext.

+#       Adam Sulmicki <adam@cfar.umd.edu>, 1st January 1997.

+# Added ability to stop at a given version number
+# Put the full version number (i.e. 2.3.31) as the last parameter
