##
##
## :D :D :D CREATES PIDGIN SMILIES :D :D :D
##
##
## Usage: add-pidgin-smily [options] IMAGE_FILE [SHORTCUT] [DIMENSIONS]
##
## arguments:
##
## IMAGE_FILE: required, the image to make a smiley
## SHORTCUT: optional, if not specified a cleaned version of the filename is used
## DIMENSIONS: optional, if not specified in the format of INTxINT, the default of 80x80 is used
##
## options:
##
## --help Display this usage message
## --verbose Display diagnostic messages
## --replace If the shortcut already exists in pidgin, replace that shortcut, otherwise an error is raised
## --force If a destination file already exists during processing, overwrite that file
## --shortcut=SHORTCUT Alternate way of specifying the shortcut to use
##
## Requires imagemagick to be installed on your machine. It probably already is, however.
