## This is a simple tool to grab shell command output from the local machine.

## To use, edit the parameters before running the command. This tool is meant
## integrate the built in fake command data in spec/data/plugins. If the
## appropriate yaml file is in this directory, this tool will append/overwrite
## the data in that file as appropriate.
