============================= 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
