argument parser generator

https://github.com/matejak/argbash

Argbash is not a parsing library, but it is rather a code generator that generates a bash library tailor-made for your script. It lets you to describe arguments your script should take and then, you can generate the bash parsing code. It stays in your script by default, but you can have it generated to a separate file and let Argbash to include it in your script for you. In any case, you won't need Argbash to run the script.

Argbash is very simple to use and the generated code is relatively nice to read. Moreover, argument definitions stay embedded in the script, so when you need to update the parsing logic, you just re-run the argbash script on the already generated script.
