Pure-python Z39.50 implementation
This code is based on the work that Dan Davis started. I did not attempt to support Python 2.7+. I have made additional changes to get the code to work with Python 3.7. My testing capabilities are limited, so i was mainly interested in updating the code to fetch MARC records from OCLC, etc. The code should now allow users to fetch MARC records from Z3950 servers using Python 3.7 (follow the zmarc_example.py, which I have updated to work with the new code changes, in the example directory).

This code is updated to support both Python 2.7+ and Python 3.5+ using 2to3 and some hand changes. The one test I got working in Python 2.7 is updated to both remain a test script and a "unit test", and that leads to test coverage of about 40%.
However, only code in PyZ3950 is actually covered by these tests. It should be assumed that the code in the example, ill, and other directories are not working properly, despite the use of 2to3.
Updating test/test2.py indicates only that the NLM Z39.50 server does not support concurrent searches.
As such, it is too early to release a new version, but there is enough here to continue. In particular, it will be good to see whether we can utilize the asn1 library and pymarc.

This code is licensed under the X license. It requires Dave Beazley's PLY parsing package from http://systems.cs.uchicago.edu/ply/, licensed under the LGPL (I've tested with both 1.0 and 1.1), and Python 2.1 (or, in all probability, later versions.)
For Z39.50 functionality, you probably just want to use ZOOM, in zoom.py. An example is in test/test1.py, which just queries the Library of Congress for works whose title begins with "1066 and all that". The documentation for the language-independent API is available at http://zoom.z3950.org/api, and I hope that should be sufficient when combined with the docstrings in zoom.py and the example. (If not, please write me.)
The ASN.1 functionality is designed to be usable separately, and lives entirely in asn1.py. I probably should split this out into its own package.
