Hi,
	Here are some minor mods to the 4.2BSD (and V7) calendar facility.
The big change is that the shell script /usr/bin/calendar scans a user's
mail file and only mails him the calendar items that he doesn't yet have
mail for.
	Minor changes include accepting $HOME/Calendar as well as
$HOME/calendar, giving you two days notice instead of just one, including
a public calendar and always reminding you of items flagged with a '*'
in place of a date.
	These mods make the calendar facility seem a little more useable.

					Cheers,
					Dan Ts'o
