If the maintainer patched filename.c, 'make patch' will create filename.c.orig (which is the original author's file) and filename.c (which is the result of the maintainer's patches.) If you edit filename.c and then diff it from filename.c.orig, the result is a patch the includes your changes AND the maintainer's. >9) Edit the patch file (now in portdir/files) so that the first two=20 >lines "point" to the actual location of the file in the working=20 >directories.
