eGenix PyRun consists of a build mechanism to build the PyRun
run-time and a set of helper modules/tools that get included in the
resulting binary. The tools and build mechanism are covered by the eGenix.com Public License Agreement 1.1.0 which is an Open Source license based on the CNRI Python license.
Since PyRun also pulls in Python during the build process to create the run-time, the respective Python license of the underlying Python source distribution also applies to the resulting pyrun binary.In simple words, you are free to use the software without paying fees or royalties as long as you give proper attribution and keep both license documents together with the software. Please see the included license documents for full details and consult a lawyer if you have legal questions.
