Oracle 10g/11g PL/SQL unwrapper 0.2 by Niels Teusink.

From: http://blog.teusink.net/2010/04/unwrapping-oracle-plsql-with-unwrappy.html

python unwrap.py infile.plb [outfile]

unwrap.py targets Python 2 (print statement, base64.decodestring, chr() returning bytes). unwrap_py3.py is a Python-3 port that preserves the original algorithm and the embedded charmap table.

python3 unwrap_py3.py infile.plb [outfile]

Smoke-tested against ~460 real Way4 (OpenWay) Oracle package bodies (~900k total lines of decoded PL/SQL) on Python 3.9.
