Unix utilities for handling comp.binaries.mac files?

[Joel Kirsh]

[My apologies if this is a second post ... I _think_ the first one died]

I'm a user of a public access Unix (actually Xenix) machine, and we (fairly)
regularly receive Binhex'd files in comp.binaries.mac.  Can someone point
me (us) to Unix/Xenix utilities that will take the c.b.m files (sometimes
in multiple parts) and convert them to Mac files *before* downloading?

Thanks for your help,
