# ---------------------------------------------------------------------------
#
# This script validates the generated guides against the W3C Validator.
#
# Guides are taken from the output directory, from where all .html files are
# submitted to the validator.
#
# This script is prepared to be launched from the railties directory as a rake task:
#
# rake validate_guides
#
# If nothing is specified, all files will be validated, but you can check just
# some of them using this environment variable:
#
# ONLY
# Use ONLY if you want to validate only one or a set of guides. Prefixes are
# enough:
#
# # validates only association_basics.html
# ONLY=assoc rake validate_guides
#
# Separate many using commas:
#
# # validates only association_basics.html and migrations.html
# ONLY=assoc,migrations rake validate_guides
#
