Bug#750643: antlr: missing licence for PyANTLR

[Thorsten Glaser]

Source: antlr
Version: 2.7.7+dfsg-5
Severity: serious
Tags: upstream
Justification: Policy 2.3

The PyANTLR component – lib/python/antlr/ in the source tree – was
written by Wolfgang Häfelinger, who, according to his website, is
German. The PyANTLR component references a “LICENSE.txt” file “for
license details”, which is missing. The top-level licence file of
antlr cannot be meant by it, because German citizens cannot disclaim
copyright and let their work wilfully enter Public Domain.

This means that PyANTLR is unlicenced proprietary software, unless
the author adds a DFSG-free licence for his code and the Debian
maintainer adds it to debian/copyright accordingly.

I’ve added Wolfgang Häfelinger to Cc, so he can comment directly
and is notified about this issue.
