 Tips for Patch Producers
 ========================
 
    To create a patch that changes an older version of a package into a
 newer version, first make a copy of the older and newer versions in
 adjacent subdirectories.  It is common to do that by unpacking `tar'
 archives of the two versions.
 
    To generate the patch, use the command `diff -Naur OLD NEW' where
 OLD and NEW identify the old and new directories.  The names OLD and
 NEW should not contain any slashes.  The `-N' option lets the patch
 create and remove files; `-a' lets the patch update non-text files; `-u'
 generates useful time stamps and enough context; and `-r' lets the
 patch update subdirectories.  Here is an example command, using Bourne
 shell syntax:
 
      diff -Naur gcc-3.0.3 gcc-3.0.4
 
    Tell your recipients how to apply the patches.  This should include
 which working directory to use, and which `patch' options to use; the
 option `-p1' is recommended.  Test your procedure by pretending to be a
 recipient and applying your patches to a copy of the original files.
