#!/bin/bash
# Simple script to generate personal, group calendars
#
# Copyright Kristofer Bergstrom 2007
#
# Released under the terms of the GNU GPL.
#
#
# Usage:
# Run from the command line, the script prompts the user to:
# Display calendar? <y/N>
# Print calendar? <y/N>
# Send significant other calendar? <y/N>
# Upload new group calendar? <y/N>
# (if yes) Email group? <y/N>
#
#
# Future features -- anyone want to help?
# Support for 1/1/07 type date entries in .calendar
# Improve ease of adoption, adaptation for others
#
#
# Before using:
# The script references the following external programs,
# not installed by default on most systems:
# pcal, gv, ps2pdf, mutt
#
# Read through the whole script! There are lots of references
# to my system that need to be changed.
# You must at least adjust the following references below to match
# your system:
# replace "/home/<username>/.calendar" with your .calendar location
# Signif. other section
# personalize echo message
# change signif. other's email address
# upload section
# change scp line to send the file to your server
# personalize the group email echo line
# change email addresses to be your group members' addresses
# change test line email address to be your email address
#
