-# ---------------------------------------------------------------------------
-#
-# This script generates the guides. It can be invoked via the
-# guides:generate rake task within the guides directory.
-#
-# Guides are taken from the source directory, and the resulting HTML goes into the
-# output directory. Assets are stored under files, and copied to output/files as
-# part of the generation process.
-#
-# Some arguments may be passed via environment variables:
-#
-# WARNINGS
-# If you are writing a guide, please work always with WARNINGS=1. Users can
-# generate the guides, and thus this flag is off by default.
-#
-# Internal links (anchors) are checked. If a reference is broken levenshtein
-# distance is used to suggest an existing one. This is useful since IDs are
-# generated by Markdown from headers and thus edits alter them.
-#
-# Also detects duplicated IDs. They happen if there are headers with the same
-# text. Please do resolve them, if any, so guides are valid XHTML.
-#
-# ALL
-# Set to "1" to force the generation of all guides.
-#
-# ONLY
-# Use ONLY if you want to generate only one or a set of guides. Prefixes are
-# enough:
-#
-# # generates only association_basics.html
-# ONLY=assoc ruby rails_guides.rb
-#
-# Separate many using commas:
-#
-# # generates only association_basics.html and migrations.html
-# ONLY=assoc,migrations ruby rails_guides.rb
-#
-# Note that if you are working on a guide generation will by default process
-# only that one, so ONLY is rarely used nowadays.
-#
-# GUIDES_LANGUAGE
-# Use GUIDES_LANGUAGE when you want to generate translated guides in
-# <tt>source/<GUIDES_LANGUAGE></tt> folder (such as <tt>source/es</tt>).
-# Ignore it when generating English guides.
-#
-# EDGE
-# Set to "1" to indicate generated guides should be marked as edge. This
-# inserts a badge and changes the preamble of the home page.
