Trolololo.
Trollop is a commandline option parser for Ruby that just gets out of your way. **DEPRECATION** This gem has been renamed to optimist and will no longer be supported. Please switch to optimist as soon as possible.
Though Trollop has the ability to support subcommands, I find myself implementing the same logic repeatedly. The abstraction of this logic is now in trollop-subcommands. This provides a framework for parsing command line options for ruby scripts that have subcommands. The format is 'script_name [global_options] subcommand [subcommand_options]'. The framework supports all the typical scenarios around these type of command line scripts. All that need to be specified are the trollop configurations for the global options and each subcommand options. See the readme for more information.
Trollolo is a command line tool to access Trello and support tasks like generation of burndown charts.
This is a temporary gem with a patch, don't use it.
