** Documentation **

The package is presented as a
[literate program document](http://repos.modelrealiztion.com/cgi-bin/fossil/mrtools/doc/trunk/posixipc/doc/posixipc.pdf),
which contains all the design information, code, and test cases.

[Man page documentation](http://repos.modelrealization.com/cgi-bin/fossil/mrtools/doc/trunk/posixipc/tea/doc/posixipc.html)
of the commands is also available.

** Development **

A TEA compliant build mechanism is available as well a
[binary Tcl module]
(http://repos.modelrealization.com/cgi-bin/fossil/mrtools/doc/trunk/packages/posixipc-1.0.tm).
The binary module works with both Linux (glibc 2.28, Tcl 8.6) and FreeBSD
(Release 12.0, Tcl 8.6).
Note that MacOSX does not support POSIX message queues and the package code
will not compile in that environment in its current state.
