[elbe-devel] [PATCH v2 1/5] elbeproject: Add gen_licenses method

[Olivier Dion]

The method check for the existance of the copyright file for each
packages of a RFS.  If a copyright file is missing, it's copied from
the buildenv.  If the file is also missing from the buildenv, then an
error is emitted.
