module Alchemy
class Page
# = The url_path for this page
#
# Use this to build relative links to this page
#
# It takes several circumstances into account:
#
# 1. It returns just a slash for language root pages of the default langauge
# 2. It returns a url path with a leading slash for regular pages
# 3. It returns a url path with a leading slash and language code prefix for pages not having the default language
# 4. It returns a url path with a leading slash and the language code for language root pages of a non-default language
#
# == Examples
#
# Using Rails' link_to helper
#
# link_to page.url
#
