Here is yet another version of "sh" -- a program to unshar file from
over the net. I wrote it from my own need--I found existing programs
to behave poorly (not understand formats, guru, etc.) I put into it
the features that were important to me (and left out the ones I didn't
need :-). Particularly, I intended it to be expandable to different
formats. At this point it understands about cat and a simple (and
common) form of sed. Adding new forms should be easy (although I have
not had needed to do this myself to unshar files I've found).

It should not need a lot of stack space to run.

I've built into it a variety of options so that it can be customized
for individual preferences. These allow one to decide how verbose its
messages are or how paranoid it is about strange forms.

I have not done extensive testing on it (remember, I originally wrote
this for myself), but I have been using it for the past six months
with no problems.

I have not included a "shar" program with this, as I found the
existing one(s) to work acceptably well.
