Are you familiar with CCMD?  I'm not sure it's very related to what you're
trying to do, but this is a tool that was developed for helping tops20 users
and programmers migrate to unix systems.  It's a C library that implements
most of the tops20 command parser, including command and filename completion,
guid words, context sensitive help, and s on.  IMO, tops20 provided the
epitomy of command line interfaces, and CCMD provides most of the features
for unix/dos/etc.  I've always wanted a CCMD based cli for modern computer
hardware...
