    # Htgroup accesses apache-compatible group files.  Htgroup can be used to
 
17
    # provide group-based authentication for users.  Currently Htgroup is not
 
18
    # directly integrated with any authenticators in WEBrick.  For security,
 
19
    # the path for a digest password database should be stored outside of the
 
20
    # paths available to the HTTP server.

    # Example:

    #
 
24
    #   htgroup = WEBrick::HTTPAuth::Htgroup.new 'my_group_file'
 
25
    #   htgroup.add 'superheroes', %w[spiderman batman]

    #   htgroup.members('superheroes').include? 'magneto' # => false
