#!/usr/bin/env bash
#
# urlcode
#   command line encode/decode of urls to clean http refs
#
# args:
#   - invoke as urlencode or urldecode
#   - send as lines on stdin, or pass as command line args, or both
#
# deps:
#   - uses php's rawurlencode() and rawurldecode(), respectively
#
# todo:
#   - url arg (ie after `+') maybe urlencode() not raw variant
#   - just write this in php itself using its `-R'
#   - we tack on a newline at end; perhaps only if stdout isatty?
