Script for dictionary lookup

# dictionary v1.5.5 - to dump dictionary outputs from the web. Uses the google dictionary but can be used for any other online dictionary.

# ANSI Color -- use these variables to easily have different color
#    and format output. Make sure to output the reset sequence after
#    colors (f = foreground, b = background), and use the 'off'
#    feature for anything you turn on.
