# THE PAIN

I've had to use some command-line utilities that had to do creative stuff to transmit
deeply nested arguments, or datastructure-like information. Here are some strategies that
I've found over time: 

## Complex arguments codified as JSON

JSON is horrible for the command line because you have to escape the quotes. It's a nightmare.

    command --complex_arg "{\"key1\":\"value1\",\"key2\":\"value2\"}"

## Arguments encoded via some custom scheme

These schemes fail when you have to make values complex (lists, or other key/values)

    command --complex_arg key1,value1:key2,value2

## Repeating Getopt arguments
