Self-contained, Python-based general-purpose iterator experiment.
Iterator iterates a list of "things" and runs one or more arbitrary system commands on each.
Here's why it's cool: It has a built-in configuration interface, and stores the config within itself. Pretty crazy huh.
# Example run
# Demonstration of "iterator.py" sample script
# A self-contained general-purpose "Thing Doer"

Mode : Command
Command : /tmp/brawl _THINGS_
Things : 63 34 /tmp/somefile.txt internalsite.corp.com
On run, each thing replaces _THINGS_.
Examples:
ping -c 1 _THINGS_
cp _THINGS_ /tmp; ls -l /tmp/_THINGS_
New command: echo "Doing _THINGS_..."
