TCX is a system designed for the transparent decompression, execution
and recompression of executables under Unix. It allows configuration
options such as the type of compression system used (compress(1),
gzip(1), your own local system etc), timeouts between recompressions,
and emergency directories in case a decompression fails from shortage
of disk space. The system is designed with a reasonable amount of
robustness in mind, such as in the event of system crashes, or races
on trying to uncompress, compress or execute something.
This software is quite old (vintage 1993-94), and some things have moved
on since then. In particular, untcx is setuid root. I have done a minor
security audit, but anyone installing this software is invited to conduct
one for themselves.

WARNING - this package contains a setuid root executable called
untcx, which was written in 1994, and contained calls to getwd(3),
sprintf(3), strcpy(3) and strcat(3). I've done a minor audit of
the code, and have fixed the above functions with calls to safer
alternatives, but you may wish to delete this package from your
own systems until you have carried out your own audit.
