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.

All this process is handled via rake tasks, here's a full list of them:

#{%x[rake -T]}
Some arguments may be passed via environment variables:

  WARNINGS=1
    Internal links (anchors) are checked, also detects duplicated IDs.

  ALL=1
    Force generation of all guides.

  ONLY=name
    Useful if you want to generate only one or a set of guides.
    
    Generate only association_basics.html:
      ONLY=assoc

    Separate many using commas:
      ONLY=assoc,migrations

  GUIDES_LANGUAGE
    Use it when you want to generate translated guides in
    source/<GUIDES_LANGUAGE> folder (such as source/es)

  EDGE=1
    Indicate generated guides should be marked as edge.

Examples:
  $ rake guides:generate ALL=1
  $ rake guides:generate EDGE=1
  $ rake guides:generate:kindle EDGE=1
  $ rake guides:generate GUIDES_LANGUAGE=es
    help
  end
end

task :default => 'guides:help'
