routes.example.py

# -*- coding: utf-8 -*-

#  This is an app-specific example router
#
#  This simple router is used for setting languages from app/languages directory
#  as a part of the application path:  app/<lang>/controller/function
#  Language from default.py or 'en' (if the file is not found) is used as
#  a default_language
#
# See <web2py-root-dir>/examples/routes.parametric.example.py for parameter's detail
#-------------------------------------------------------------------------------------
# To enable this route file you must do the steps:
#
# 1. rename <web2py-root-dir>/examples/routes.parametric.example.py to routes.py
# 2. rename this APP/routes.example.py to APP/routes.py
#    (where APP - is your application directory)
# 3. restart web2py (or reload routes in web2py admin interfase)
#
# YOU CAN COPY THIS FILE TO ANY APPLICATION'S ROOT DIRECTORY WITHOUT CHANGES!
