Overview

Handles configuration for Rack::Less Available config settings: :cache

whether to cache the compilation output to
a corresponding static file. Also determines
what value config#combinations(:key) returns

:compress

whether to remove extraneous whitespace from
compilation output

:combinations

Rack::Less uses combinations as directives for
combining the output of many stylesheets and
serving them as a single resource.  Combinations
are defined using a hash, where the key is the
resource name and the value is an array of
names specifying the stylesheets to combine
as that resource.  For example:
  Rack::Less.config.combinations = {
    'web'    => ['reset', 'common', 'app_web'],
    'mobile' => ['reset', 'iui', 'common', 'app_mobile']
  }

:cache_bust

whether to append a timestamp to the sheet requests generated by combinations
