BTW,
I was looking at this license stuff yesterday. Since verveineJ is based on JDT and JDT uses the EPL (Eclipse Public License), VerveineJ could be required to use the EPL also ...
"According to article 1(b) of the EPL, additions to the original work may be licensed independently, including under a commercial license, provided such additions are "separate modules of software" and do not constitute a derivative work.[4][5] Changes and additions which do constitute a derivative work must be licensed under the same terms and conditions of the EPL, which includes the requirement to make source code available" [http://en.wikipedia.org/wiki/Eclipse_Public_License]
"The EPL is approved by the Open Source Initiative (OSI) and listed as a "free software license" by the Free Software Foundation (FSF)"
any comment?
