This is a pure-python library for decoding Microsoft's Transport Neutral Encapsulation Format (TNEF). See for example wikipedia for more on TNEF.
The library can be used as a basis for applications that need to parse TNEF. There are some tests; run 'python setup.py test' or 'python runtests.py'.
A command-line utility "tnefparse" is also provided that gets installed as part of the package, that can be used to list contents of TNEF files and extract attachments found inside them (requires python >= 2.7).
