PyTalker is quite quite dead. This isn’t even PyTalker’s latest version, or a version at all, this is a development snapshot of what almost came to be PyTalker 0.3.0 (but never really did anyway).
– from README
PyTalker was started by the same author who forked Mamnuts and would later create TalkerNode. All behave in the style of NUTS-family talkers, but PyTalker uses the Python language and is not derived from the original NUTS source code in C.
