Some suggestions for changes to command options:

  * --verbose:
    * add alternate: -v

  * --from:
    * replace with: -s $SOURCE || --source=$SOURCE

  * --to:
    * replace with: -d $DESTINATION || --destination=$DESTINATION

  * --force:
    * add alternate: -F
      * "-f" was removed in v0.20110417
      * since it forces unsafe operations, should be capitalized to reduce chance of accidental usage.
