## You need python-webkit and python-pylirc
## Put the URL to your Google calendar (or some other page)
## into ~/.calendar_url
## You need something like this in your lircrc:
#begin
# button = Back
# prog = mythcalendar
# config = quit
#end
## Then edit your MythTV menu (e.g. /usr/share/mythtv/themes/DVR/mainmenu.xml)
# <button>
# <type>MENU_UTILITIES_SETUP</type>
# <text>Calendar</text>
# <action>EXEC "/var/lib/mythtv/bin/mythcalendar.py"</action>
# </button>
# This is derived from http://code.google.com/p/pywebkitgtk/source/browse/trunk/demos/tabbed_browser.py
# I'll be taking OUT more tabbed support, and then ADDING
# more lirc based control
