由vrms想到

vrms是Virtual Richard M. Stallman的缩写。想必大家已经知道Stallman是何许人也。
vrms的功能是去除你系统中的non-free软件。
一些人已经开始清除PC里的non-free software，而我们却还在为找到一个更好的盗版软件而奋斗。

注：ubuntu官方源已添加该软件包。该软件包说明说下：

virtual Richard M. Stallman
The vrms program will analyze the set of currently-installed packages on a
Debian GNU/Linux system, and report all of the packages from the non-free
tree which are currently installed.
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.
