What are the licensing restrictions for Hercules?
Hercules is a copyright work which has been made generally available, subject to the terms of the Q Public License. In essence this allows free use and distribution of the program for personal and commercial use. You may not distribute modified copies of the program, but you may distribute your own patches along with the program, provided that you also grant the maintainer permission to include those patches in future versions of the program. You may not copy any portion of the source code for use in any other program. Hercules is not, repeat, not GPL software! The GNU General Public License is a Unix/Linux software licensing agreement, which we, the authors, will not participate in. We believe that the QPL, which has been certified as compliant with the Open Source Definition, provides the benefits and protections of open source for both users and developers, without the political baggage that has come to be associated with the GPL.
