Clipboard to Google Calendar

I enjoy a good shell script, so here's what I cobbled together. This script requires Mac OS X (every version so far has pbpaste) with the Google CLI (gdata-python-client, I used version 2.0.17) installed. The basic command is google calendar add --cal Calendar "Event 1/4/2013 at 3:00 PM in Location" but I used a script for error checking, and I only have to scroll back to the last error to see all of the problematic entries.

#! /bin/bash

## This script sends the clipboard to Google Calendar one line at a time.
## REQUIRES: Google cli from http://code.google.com/p/gdata-python-client/
