Pack/Unpack under 4.2 BSD?

[Robert Rother]

[Obligatory Non-blank first line]

I have some files that have been compressed with the older (?) 
UNIX (tm) command pack.  Unfortunatly these files are residing on a
4.2 BSD Vax that doesn't have the utility to unpack these.  Are the
sources for these commands propietary?  If not could someone please
mail me a pointer to where I can get them.

Thanks,
