Terry, I will be the first to admit I'm no lawyer, but I thought that the output from bison was not in itself GPL'ed, just the bison code itself. Let me quote the part I think is relevant from the COPYING file from bison 1.25: "Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does." I am looking at the line that says the output of the program isn't restricted. Doesn't that mean that the output of bison isn't GPL'ed? ----------------------------+----------------------------------------------- Chuck Robey | Interests include any kind of voice or data chuckr@eng.umd.edu | communications topic, C programming, and Unix. 9120 Edmonston Ct #302 | Greenbelt, MD 20770 | I run Journey2 and picnic, both FreeBSD (301) 220-2114 | version 3.0 current -- and great FUN! ----------------------------+-----------------------------------------------
