Reminds me of my old "comnd" library written in C which implements
quite a bit of the TOPS20 COMND JSYS functions, including some extra
stuff such as alternate parse paths and guide words.  This was, in
fact, the code library used by Cisco 20 years ago or so when they
produced their first CLI using command completion.  I did a rewrite
and cleanup since that time, and I would bet they did too :-) As fate
would have it, I have lost the rewritten version.

I would also be willing to bet that there are newer and better
implementations of COMND nowadays.  I did know of a couple at one
point, include the one used by "kermit" (ccmd, I think) and at least
one other, perhaps written in Tcl.
