# This module implements automatic protection and unprotection of
# wikipedia pages. It is designed to be used with the Python Wikipedia
# Robot Framework (http://sourceforge.net/projects/pywikipediabot/).
#
#
# USAGE
#
# You must use login.py to log in as a user with administrator
# privileges in order for this module to be effective. Then you can use
# it like this:

#   import protect
#   protect.protectPage(pagelink, 'reason for protecting')
#   protect.unprotectPage(pagelink, 'reason for unprotecting')
