Re: Problems porting from old Compilation Manager

Hi Joe,

Thanks for the reply. Yes, both Version and PackageManager are part of
MLj. I couldn't find a .cm file that looked likely anywhere, either in
the binary or source distributions. I'll have to read up about the CM
and see if I can figure it out.

Thanks,
Colin
