There have been a number of postings recently that were updates to various
programs given in the form of differences.

I am pleased that you are trying to save the net by shipping differences
only, but I find it to be a real time burner to have to manually go through and
apply this stuff if it looks worthwhile.

For this very reason, I wrote a procedure which takes the pain out of the
process.  The idea is simple -- it really just automates what anyone can
do manually.

I submitted this goody back on 31 Dec 1987, but am posting it here again.

This procedure, bundled inside of a shar file, is designed to generate the
SUMSLP differences, set up a build procedure, and package the whole thing
up using Michael Bednarek's VMS_SHAR utility.  

When differences have been packaged this way, the procedure for
applying them is as follows:

1.  @ the shar file, which unpackages the update procedure

2.  @ the update procedure, supplying the file name to be updated and the
    file name for the result to go to.

I originally wrote this for procedure for the purpose of shipping local
modifications to DEC supplied software, so as not to violate the licensing
agreement(s).   It works just as well for shipping updates as differences.

Please try this out and see what you think.  If you have suggestions for
enhancements, please send MAIL directly to me.
