  module Mime
    # Returns String with mime type if found, otherwise use +fallback+.
    # +ext+ should be filename extension in the '.ext' format that
    #       File.extname(file) returns.
    # +fallback+ may be any object
    #
    # Also see the documentation for MIME_TYPES
    #
    # Usage:
    #     Rack::Mime.mime_type('.foo')
    #
    # This is a shortcut for:
    #     Rack::Mime::MIME_TYPES.fetch('.foo', 'application/octet-stream')

    # Returns true if the given value is a mime match for the given mime match
    # specification, false otherwise.
    #
    #    Rack::Mime.match?('text/html', 'text/*') => true
    #    Rack::Mime.match?('text/plain', '*') => true
    #    Rack::Mime.match?('text/html', 'application/json') => false

    # List of most common mime-types, selected various sources
    # according to their usefulness in a webserving scope for Ruby
    # users.
    #
    # To amend this list with your local mime.types list you can use:
    #
    #     require 'webrick/httputils'
    #     list = WEBrick::HTTPUtils.load_mime_types('/etc/mime.types')
    #     Rack::Mime::MIME_TYPES.merge!(list)
    #
    # N.B. On Ubuntu the mime.types file does not include the leading period, so
    # users may need to modify the data before merging into the hash.
