-**
-** python.c: Embed Python in the style of nnrpd's TCL and Perl stuff
-** (authentication and authorization hooks only at this point).
-**
-** Written by Ilya Etingof <ilya@glas.net>, 1999.
-**
-** This code bases on Python work for innd filtering done by
-** G.J. Andruk <meowing@banet.net>. Also it borrows some ideas from
-** TCL/Perl work done by Bob Heiney and Christophe Wolfhugel.
-**
-** A quick note regarding Python exceptions: functions like
-** PyObject_GetAttrString(PyObject *o, const char *attr_name)
-** raise an exception when they fail, even though they return NULL.
-** And as exceptions accumulate from caller to caller and so on,
-** it generates weird issues with Python scripts afterwards. So such
-** uses should be checked before. For instance with:
-** PyObject_HasAttrString(PyObject *o, const char *attr_name).
