or Open Source Software
circles, RMS is the abbreviation for Richard M. Stallman. RMS is most famous for his founding of the Free Software Foundation
, which takes the idea open source software further into saying that software should be free, but free as in speech, not free as in beer
RMS served as leader of the FSF since roughly the mid 1980s, while also working on a variety of software programs, including, most famously emacs, the text editor cum operating system, some have said.
Recently, Bradley Kuhn has become Vice President of the FSF, giving Richard more time to pursue some of the philosphical aspects of the FSF
