============================= cmdcat demo ===================================

Cmdcat obviously doesn't work correctly here, but I'm not sure if I'm building/holding it wrong, or if it's just not yet fully functional. In any case, it's not a huge program--I assume the Nix community could help get it on the right track.

The sizes of these on my NixOS box as reported by nix path-info -Sh are:

• cmdcat: 43.0M
• red: 99.3M
• clade 176.7M
