[tex-k] TeX and IPC

[Karl Berry]

    Question: which Unix programs use TeX's IPC communication 

PyTeX is the only one I know of.
http://www.pytex.org/texd/

    what is their definition of the IPC messages?

No idea.


For the record ... Tom Rokicki wrote the IPC stuff for the NeXT and his
TeXView.app there, which tells you its age.  For a "recent" message from
Tom on the subject:
