### SO HOW DO YOU PROCEED WITH YOUR SCRIPT?
### 1. define the flags/options/parameters and defaults you need in Option:config()
### 2. implement the different actions in Script:main() with helper functions
### 3. implement helper functions you defined in previous step

### will be available as $<long> in the script e.g. $verbose
### option: set an option / 1 value specified
### option|<short>|<long>|<description>|<default>
### e.g. "-e <extension>" or "--extension <extension>" for a file extension
### will be available a $<long> in the script e.g. $extension
### list: add an list/array item / 1 value specified
### list|<short>|<long>|<description>| (default is ignored)
### e.g. "-u <user1> -u <user2>" or "--user <user1> --user <user2>"
### will be available a $<long> array in the script e.g. ${user[@]}
### param: comes after the options
### param|<type>|<long>|<description>
### <type> = 1 for single parameters - e.g. param|1|output expects 1 parameter <output>
### <type> = ? for optional parameters - e.g. param|1|output expects 1 parameter <output>
### <type> = n for list parameter - e.g. param|n|inputs expects <input1> <input2> ... <input99>
### will be available as $<long> in the script after option/param parsing
### choice: is like a param, but when there are limited options
### choice|<type>|<long>|<description>|choice1,choice2,...
