go-magic-cli
This is a work-in-progress Go reimplementation of @slackhq's magic-cli.
The idea is to make a collection of related commands in separate scripts look like one command in one script. I originally started reimplementing it because on the HPC clusters we work on we change up environment variables a lot, so especially things that depend on scripting languages can break if something becomes not available or changes version from the one the author expected. Maybe I should have done it in bash instead of Go, though.
