Good question. Actually the dog an pony show was more meant for Brent
and Alan i(f he is going to be there), but I guess a few extra people
doing review wouldn't hurt. I am currently scheduling a list managers
BOF for sometime after 8PM on Tuesday, so the show won't occur before
the BOF.

Yes, I could see that too. Actually I think it may not be a problem
because I think I have a scheme to allow Alan's method of single
keyword setting to work.

I just realized that the full add in modules discussion (mixins if you
will) may not have made it to the list. This is the way I envision it
working:

  majordomo loads all of the files in a directory "addins". Each addin
  has perl code to register its new commands with the main majordomo
  parser, and most importantly to provide help info for the commands.
  Each addin could also register its keywords with the config file
  parser, so that it would share the same configuration mechanism as
  the rest of the majordomo package.

The addin code could easily provide stubs to trigger an autoload of
the real code when it is needed. This would help to reduce the startup
time. If a help directive was needed, the newly registered function
names would be displayed with a tag indicating that they were
non-standard majordomo commands. This should allow easy
differentiation between the standard and non-standard commands.

Actually I would like to make it a non-existant feature 8-). However,
since it should be able to be implimented as an addon (post_newconfig,
do_get_config_version ...), you just don't put the file implementing
the function in your addon directory. Also implementing one in rcs,
and one is sccss shouldn't be all that hard. Then a site can choose
which version of the "scs_config" package thay want. Heck you can even
create one based on cvs if you like.
