The software should be usable by reading the docstrings. If you think that certain features are missing or you found a bug, don't hesitate to ask me via mail! Supported Python versions currently are 2.5 and 2.6. It might still support 2.4, but I did not test that. 3.x is currently not supported, because the syntax is incompatible. However the fixes needed to make the code usable with 3.x should be small. Eventually there will be a 3.x branch. Helmut Grohne
