 * Fast, minimalistic declaration of arguments your script expects (positional, optional, long, short, boolean).
 * Generate script from definitions once and use it afterwards on all platforms that have `Bash`!
 * Definitions will stay embedded in few lines of the script itself (so you can use `Argbash` to regenerate the parsing part of your script easily).
+* You can re-use low-level `Argbash`-aware scripts by wrapping them by higher-level `Argbash`-aware ones conveniently, without duplicating code.
 * Easy installation. Just [grab a release](https://github.com/matejak/argbash/releases), unzip it, go inside and run `cd resources && make install` (you may want to run `sudo make install PREFIX=/usr/bin` for a system-wide installation).
 * [Documentation](http://argbash.readthedocs.org/en/latest/) and [examples](resources/examples).
