Aloy, she is great. She is capable of everything. So i named my own zero-dep (for now atleast) NodeJS utilities / recipes /sandbox repo after her. I dont have idea why would anyone other than me want to use this, but if you want for some reason; use tests as documentation.
argv: cli argument parser, my own 80 line alternative for minimist. Parsing result is very similar to minimist with some nuance. Check tests. (code, tests)
