  yes, thank you, both of those have been recommended 
to me and i have them bookmarked for further study.

  ok.  i'm one of those people who hates extra
files being left behind when they are autogenerated
anyways, but i see your point.  thanks for putting
me straight.

  ok, i will leave it alone then.  out comes the

  heheh, oops.  yes, you are right below in saying that
i misunderstood the meaning of distcheck.  i thought it
simply verified that the files meant to be distributed
are those that are in the archive.

  yes, very much, thanks.

  the good news is that i was able to use the
simple example to figure out how to replace a
framewerk wrapped collection of programs.  something
i've wanted to do for a few years.  now that
collection is all set up without an extra layer
of build complexity.  progress.  next item, update 
some document files and it's ready to go.

  thanks again,
