`--help` flag to show options

As far as I can tell this tool has no way to figure out the synopsis without either looking at the code or going to the readme in this repo.

Thanks, yes, that is true. This project started as a proof-of-concept and as such fully focussed on validation and nothing else. As such the CLI interface is very bare-bone. Would be nice to have though. I'm open to PRs, should not be too hard to do (with yargs instead of minimist). I'm currently slammed with work for STAC Browser, but will keep an eye on it.

Thanks! I probably won't have time to work on this, and also I'm not very familiar with the tool stack (except Node.js itself).

A very minimal help output is now available:

> stac-node-validator --help
STAC Node Validator v1.1.0

For more information on using this command line tool, please visit

I'll not implement a full-fledged help section anytime soon, but happy to accept PRs.

Leaving this open, maybe someone else wants to contribute something. :-)

Implemented and released with 2.0.0-beta.1.
