# Extraction of the methods dynamically added by the Geometry 
# module plug-in(s) to the geomBuilder class.
# 
# This script is intended for internal usage - only
# for generatation of the extra developer documentation for
# the Geometry module plug-in(s).
# 
# Usage:
#       collect_geom_methods.py <plugin_name>
# where
#   <plugin_name> is a name of the plug-in module
#
# Notes:
# - the script is supposed to be run in correct environment
# i.e. PYTHONPATH, GEOM_PluginsList and other important
# variables are set properly; otherwise the script will fail.
