	Hello. 

	I would like to set up MH-6.7 on my 2.1 NeXT to use Mach shared 
libraries. This could save some disk space and even some memory. I looked
in the online docs and asked around, but no luck. The online docs mention
the bits laid out in a shared library, but they don't say how to create
one with UNIX commands. (I suspect it will entail creating programs that
do not use global variables, so that they are re-entrant, maybe some
compiler flags, and that some form of the ld command can be used to lay
out the bits in the file properly, I just don't have any examples.) 

	If someone out there would be kind enough to send me some info on
this, so I can complete the changes, I would love to put my MH-6.7 patches
for NeXT shared libs out on the archives, and submit a note to the FAQ
people. (Thanks again Pascal, John and Erik!) 

	MH-6.7 can be built to use shared libraries on Suns quite easily, so
there should not be too much work involved for the NeXT. (Unless I am
wrong about how strict the limits are for global variables and such. I
could not find any info on that, either. I am just extrapolating from bits
and pieces.)

	I have two more questions. Where can I get the source for a really
good email archive server? We would like to set one up on the rmNUG NeXTWorking
machine. What I mean by good, is that it is written well, and has the
functionality that allows it to split up, compress, uuencode, use different
return paths, auto-generate archive listings with checksums, etc.

	Also, is anyone out there using my CVS/RCS patches for the NeXT? I
have not heard any complaints from the few people I gave sets of patches
to, so please give me some feedback so I can put them on the archives.
			Thanks,
				Karl Sierka
