Heh.  When I said "undocumented," I meant in my readme.dos file.
I HAD known about that feature of p?mmerge, but since I never
used it, forgot about it.  I remembered it long after I'd released
the package.

Perhaps.  But it also saves inodes on truly space stressed
systems.  (picking nits, I know ;-).  Actually, the OS/2 port of
PBMPlus did use the shard library approach.  Each of the
appropriate *.a file was changed to a dll, and each executable
was made to load that dll.  As a result, each executable was
around 3-4k in size (if I remember correctly).  Perhaps when
DJGPP 2.0, complete with DLL's, come out, such a similar port
could be done.
