*That being said, I do not know why the antlr *.jar file includes the Python code, as it does not need to. If the antlr upstream distributes the binary *.jar file with it, thiswill not be a problem.* This sentence is still confusing. It is a fact that antlr2-*.jar does not contain *any* Python code. However, it contains the Java part of the pyAntlr code generator plugin (path: antlr/actions/python/**). This code is written by me, however, nowhere are the words "copyright" or "license" mentioned. Therefore I conclude, that this code is fully covered by LICENSE.txt listed in the root of antlr-*.tar.gz (or other distributions listed at http://www.antlr2.org/download.html). Thus there is a remaining Python part in "lib/python", part of the source code distribution (http://www.antlr2.org/download/antlr-2.7.7.tar.gz). Indeed, the license details are there in a bad shape. My proposal to get rid of the problem is: (a) pyANTLR-*.jar => The pyANTLR code generator plugin for Python written in Java, depending on antlr-*.jar. Technically, this would be the "antlr/actions/python/**" part found in the antlr*.jar file (b) pyANTLR.zip => The pyANTLR Python library. Technically, this would be the "lib/python/**" part of antlr-*.tar.gz (or other source code distribution) modified to have a proper license while otherwise unchanged. You, Debian, you would then ignore (or wipe) the pyANTLR part of the original antlr-2.* distribution and instead add at least (b) to your system. Your comments please.
