There is no CABAL.
Well, maybe there is. CABAL is a group of enthusiasts of the GNU/Linux operating system in the San Francisco Bay Area. We meet every 2nd and 4th Saturday from 4 pm to midnight at 1105 Altschul Avenue near Alameda de las Pulgas, Menlo Park.
We also are a shadowy force helping run InstallFests, both our own and those of other GNU/Linux & BSD user groups.
