calendar.c:
- fixed a bug introduced in 1.1 where getting an error while
reading the calandar file could cause an infinite loop
- added "ChangeLog" comments for all versions
- added stack checking
- eliminated "pragma stacksize" from the source file; it was too
small (was 512 bytes, currently using 862 bytes) and overriding
the value given on the command line during the GNO base build
process
README, calendar.info:
- Moved the information in these files to the man page.
Makefile, calendar.rez:
- initial checkin
calendar.1:
- cleaned it up a bit and made it conform to the GNO base builds
- added an example
