Liston,

Using the command

    diff -u old_file new_file > patch_description.txt

The first diff below looks like it has the old and new file reversed,
which makes it harder to apply.

Also, I'll need a log file change for this to place at the top of
orcallator.se and in the Orca package.

I'm working on getting Orca into Subversion source code management
so that people do diffs between the source code and their mods and
send them in for inclusion in the package.

Once you have some data for this, adding an entry to the

   http://www.orcaware.com/orca/docs/orcallator.html

would be great.

Best,
Blair
