+# version 0.5.2 2007-03-23
+# 	- BUG: leadtime for recurring events had a max of 4 instead of DEFAULT_LEAD_TIME
+#	- remove project-lead-time, since Category was a non-standard attribute
+#	- NOTE: There is a bug in iCal::Parser v1.14 that causes multiple calendars to
+#		fail if a calendar with recurring events is followed by a calendar with no
+#		recurring events.  This has been reported to the iCal::Parser author.
+# version 0.5.1 2007-03-21
+#	- BUG: Handle multiple calendars on STDIN
+#	- add --heading option for priority on section headers
+# version 0.5 2007-03-21
+#	- Add more help options
+#	- --project-lead-time option
+#	- Supress printing of heading if there are no todos to print
+# version 0.4
+#	- Version 0.4 changes all written or inspired by, and thanks to Mark Stosberg
+#	- Change to GetOptions
+#	- Change to pipe
+#	- Add --label, --help options
+#	- Add Help Text
+#	- Change to subroutines
+#	- Efficiency and Cleanup
+# version 0.3
+#	- Convert to GPL (Thanks to Mark Stosberg)
+#	- Add usage
+# version 0.2
+#	- add command line switches

+=head1 SYNOPSIS
+
+ cat /path/to/file*.ics | ical2rem.pl > ~/.ical2rem
+
+ All options have reasonable defaults:
+ --label		       Calendar name (Default: Calendar)
+ --lead-time	       Advance days to start reminders (Default: 3)
+ --todos, --no-todos   Process Todos? (Default: Yes)
+ --heading			   Define a priority for static entries
+ --help				   Usage
+ --man				   Complete man page
+
+Expects an ICAL stream on STDIN. Converts it to the format
+used by the C<remind> script and prints it to STDOUT. 
+
+=head2 --label
+
+  ical2rem.pl --label "Bob's Calendar"
+
+The syntax generated includes a label for the calendar parsed.
+By default this is "Calendar". You can customize this with 
+the "--label" option.
+
+=head2 --lead-time 
+
+  ical2rem.pl --lead-time 3
+ 
+How may days in advance to start getting reminders about the events. Defaults to 3. 
+
+=head2 --no-todos
+
+  ical2rem.pl --no-todos
+
+If you don't care about the ToDos the calendar, this will surpress
+printing of the ToDo heading, as well as skipping ToDo processing. 
+
+=head2 --heading
+
+  ical2rem.pl --heading "PRIORITY 9999"
+
+Set an option on static messages output.  Using priorities can made the static messages look different from
+the calendar entries.  See the file defs.rem from the remind distribution for more information.
