Informações que constam no synaptic sobre o VRMS:

Virtual Richard M. Stallman
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 tree which are currently installed.

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.

Future versions of vrms will include an option to also display text
from the public writings of RMS and others that explain why use of each
of the installed non-free packages might cause moral issues for some in
the Free Software community. This functionality is not yet included.
