OpenWFE is a workflow engine. It is robust, extensible, and scalable. Access libraries for Python, Perl, and .NET make it easy to write custom interfaces or agents (automatic participants) for a workflow-enabled system.

This version finished the implementation of workflow patterns, including the 'discriminator' pattern and its generalization, the 'N out of M' pattern. This feature tells that at a merge point (the end of a 'concurrence') only a certain number of incoming branches are taken into account, the other being cancelled or forgotten (their execution continues, but they will never reach the main flow).
