That’s excellent!  I am excited to take a closer look at Gash with all
the progress made over the last month.

Hmm....  A puzzle indeed.  Spinning off the core-utils stuff makes
sense.  I always assumed that there would be some way in Geesh to
dynamically add built-ins.  The Geesh front-end is isolated from the
rest of it, and could be pulled out with no trouble.

Ultimately, I would like us to coordinate and consolidate what we have
into a unified whole (even if it that whole is made of multiple
packages).  I will take a close look at Gash, and then I will message
you with any plans I come up with for moving forward.  Feel free to
message me with whatever ideas you have, too.  I’m sure we can figure
this out.  :)
