Summary: the actual process


  the following is an excerpt from a README.local file that i maintain
  in my emacs directory in case i die tomorrow and someone should have
  to maintain emacs here.

  it describes the method that use to get patch to work as
  automatically as possible with the minimum amount of editing of the
  diff file.

  i'll welcome any improvements in wording or design to this method.

NOTE: the example given in this README file was that we were upgrading
from dist-18.33 to dist-18.35.

* Incorporate the diff file.
** Edit the diff file.  
*** Write the "new file" portions to their respective files.  
*** Remove any diff references to non-existent files.  For instance, I
    do not maintain cpp or shortnames directories.
** Run patch on the diff file.
*** First, move the diff file into the same directory that contains
    the emacs directory.  Make a symbolic link from a file called
    dist-18.33 to the emacs directory.  The actual name of this file
    is taken from the diff file.  Pick either the old or new
    distribution name for the symbolic link.  
*** Then run "patch -p < diff-18.33-18.35" (or whatever your patch
    file is) and watch the fun.  The symbolic link can then be
    removed.  You may have to manually edit some files if the patch
    fails--this is where you get to be creative.
** Remove the .rej and .orig files created by patch once you feel that
   everything is right.
