It sounds very cool -- anything which means less work writing and maintaining parsers sounds a Good Thing to me :-). Like Simon, I was a little concerned by the licencing issue. However, checking: http://www.jflex.de/copying.html I see the following: The code generated by JFlex inherits the copyright of the specification it was produced from. If it was your specification, you may use the generated code without restriction. Which I think puts us in the clear. I can't see any problems with using an extra GPLed tool at compile time. Any other thoughts on this? Thomas. _______________________________________________ Biojava-l mailing list - [EMAIL PROTECTED] http://biojava.org/mailman/listinfo/biojava-l
