Ruby makes advanced CLI options easy | justin․searls․co

If you're not a "UNIX person", the thought of writing a command line application can be scary and off-putting. People find the command line so intimidating that Ruby—which was initially populated by a swarm of Windows-to-Mac migrants—now boasts a crowded field of gems that purport to make CLI development easier, often at the cost of fine-grained control over basic process management, limited option parsing, and increased dependency risk (many Rails upgrades have been stalled by a project's inclusion of another CLI gem that was built with an old version of thor). Good news, you probably don't need any of those gems!.
