[lug] ptx macros for troff wanted

[scoffin at attbi.com]

I'm looking for a copy of the "ptx" or "mptx" macro package for
[tg]roff, or at least a definition of the "xx" macro.  Users of
linux or groff probably don't have it, but on real :-) UNIX
systems it might be in /usr/lib/tmac/tmac.ptx or maybe mptx.
or maybe /usr/share/troff/tmac, /usr/share/ditroff/tmac/, or maybe....

Thanks for any help, if you have this can you email a copy to me?
