# This is an example of an Extension Module to provide User Supplied
# Authentication Methods.
#
# It mimics the behaviour of the pgAuthSource Module, and the sql queries
# Used here would be added as ZSQLMethods in the usAuthSource Folder.
# (you can basically cut and paste them from the bottom of this .py file
# into the ZSQL Method Template Area
#
# It's not complete, but, you do get the idea...
#
# Each function becomes usFunctionName
#
# e.g. listOneUser -> usListOneUser
