Re: GIT and COGITO individual scripts hidding from PATH

Excuse me for resending of e-mail again, but I have forget
to disable wrapping of lines. Sending as attachmet would be
more secure, but I do not know, if it is convenient
on the git list.

The "cgt" is wrapper for all cogito programs. If cogito is
build and installed to any prefix directory (/opt/git-cogito in my case)
and script is copied to bin subdirectory (/opt/git-cogito/bin),
then only single symbolic link from some searchable directory on PATH
is enough to call all cogito commands
  cgt pull
  cgt update
so usage is more convenient for my fingers learned to type cvs up, etc.
I think, that addition of intelligent bash completion could be done easier
if number of the first level commands to cover is smaller.
