-# This script allows you to run Athena from python. It is developed against
-# the cppyy based GaudiPython and python 2.6/7.x.
-#
-# Debugging is supported with the '-d' option (hook debugger after running
-# all user scripts, and just before calling initialize) and the --debug
-# option (requires "conf", "init", or "exec" and will hook just before that
-# stage). The hook will give you the gdb prompt, from where you can set
-# break points, load additional shared libraries, or drop into interactive
-# athena mode (if -i specified on the cli). Alternatively, you can start
-# with gdb, like so:
-#
-#  $ gdb python
-#  (gdb) run `which athena.py` [options] [<file1>.py [<file2>.py ...
-#
-# Usage of valgrind is supported, but it requires full paths and explicit
-# arguments in its run, like so:
-#
-#  $ valgrind `which python` `which athena.py` [options] [<file1>.py ...
-#
-# or, alternatively (valgrind 3.2.0 and up):
-#
-#  $ valgrind --trace-children=yes `which athena.py` [options] [<file1>.py ...
-#
-# Note that any error messages/leaks that valgrind reports on python can be
-# ignored, as valgrind is wrong (see the file Misc/README.valgrind in the
-# python installation).
-#
-# Additional details on debugging are available on the Wiki:
-#
-#   https://uimon.cern.ch/twiki/bin/view/Atlas/StartingDebuggerWithAthenaPy
