A small ? a/b licensing issues

Not to rain on any parades, but I was looking around and noticed this: excerpt from http://www.gnu.org/manual/bison/html_chapter/bison_2.html#SEC2 Bison grammars can be used only in programs that are free software. This is in contrast to what happens with the GNU C compiler and the other GNU programming tools. The reason Bison is special is that the output of the Bison utility--the Bison parser file--contains a verbatim copy of a sizable piece of Bison, which is the code for the yyparse function. (The actions from your grammar are inserted into this function at one point, but the rest of the function is not changed.) As a result, the Bison parser file is covered by the same copying conditions that cover Bison itself and the rest of the GNU system: any program containing it has to be distributed under the standard GNU copying conditions. ---- end excerpt So, what a/b software that uses a "Qt/Open Source" type license? is that GNU compatible? Just a question... --Joey Smith
