makepatch

generate/apply patch files with more functionality than plain diff

This package contains a pair of programs, makepatch and applypatch, to assist in the generation and application of patch kits to synchronise source trees. makepatch knows about common conventions for patch kits (it generates Index: and Prereq: lines, it patches patchlevel.h first, it can use manifest files), plus it prepends some shell code which if run will take care adding directories, removing files, setting execute mode on scripts, and the like. applypatch uses some extra data supplied by makepatch to verify both the patch and the source directory before applying the patch. Afterwards it will clean up the directory tree plus fix up the permissions and even the timestamps on the patched files.
