vrms - 1.27 main

The vrms program will analyze the set of currently-installed packages
on a Debian-based system, and report all of the packages from the
non-free and contrib trees which are currently installed.
.
In some cases, the opinions of Richard M. Stallman and the Debian project
have diverged since this program was originally written. In such cases, this
program follows the Debian Free Software Guidelines.
.
Note that vrms is not limited to Debian systems only (which means that
it also works with Debian-derived distributions such as Ubuntu). It is
also not limited to Linux-based systems.
