For an example, see the "bash autocompletion" project:
http://freshmeat.net/projects/bashcompletion/
This hooks arbitrary commands to arbitrary shell functions. When
"<Tab><Tab>" is used to try and auto-complete a command, the appropriate
shell function is executed to generate the list of possible completions.
Somebody has already contributed a function for "configure" commands. If you
..../configure --<tab>
the function runs "configure --help" and then strips out the possible
completions. It's rather handy.
I've already sent in another function to do the same thing with the GCC
frontends, e.g., typing "g++ -f<tab><tab>" will list all the -f* options.
Yet more motivation for documenting the options...

Win some, lose some. :-)
