Revision 463, 5.8 kB (checked in by jerome, 15 years ago)

Licensing terms changed to GNU GPL v3.0 or higher.
Removed old PCL3/4/5 parser which for a long time now wasn't used
anymore, and for which I was not the original copyright owner.
Version number bumped to 3.00alpha to reflect licensing changes.

  • Property svn:eol-style set to native
