Note, though, that the GNU GPL can be used for general data which is not software, as long as one can determine what the definition of "source code" refers to in the particular case. As it turns out, the DSL also requires that you determine what the "source code" is, using approximately the same definition that the GPL uses. mindguard public license for memetic protection http://zapatopi.net/mgpl.html ==== opensource + free software ==== * Free/Libre and Open Source Software: Survey and Study http://www.infonomics.nl/FLOSS/index.htm * [[Free Software]] and [[Open Source]] * pinko-commie sympathisers.. .
