dfs@doe.carleton.ca (David F. Skoll) (11/17/90)
This is REMIND version 2.2. It has all the advanced date calculation
features of REMIND 2.1, as well as:
- The addition of a time field.
- The ability to run in the background and issue reminders at a specific
time. You can be reminded in advance of the time, and have the reminder
repeatedly remind you with a specified interval.
- The addition of a "calendar" facility - REMIND will examine your reminder
file, and produce an annotated calendar for printout.
- The source code has been cleaned up so that REMIND compiles quietly
on an MS-DOS machine, and should work on SYSV machines with no modification.
Because so much code was modified, I'm posting the whole thing, rather than
patches. So here goes...

XREMIND 2.2 for MS-DOS
X
XFirst, read the files COPYRIGHT and WHATSNEW.22.
X
XREMIND was originally written for MS-DOS. To compile it, you need
Xthe Microsoft C compiler (at least version 5.1) and the Microsoft
XMAKE utility.
X
XBefore compiling the software, check if it includes patches. These
Xare files called patch.xx. If there are patches, apply them all by typing
X
Xcat patch.* | patch
X
XTo compile the software, simply go to the source directory and type:
X
XMAKE REMIND.MAK
X
XNote that the MS-DOS version of REMIND operates slightly differently from
Xthe UNIX version: MS-DOS has no concept of file access date. Thus, to
Ximplement the "ONCE" keyword, REMIND will change the modification date
Xof the top-level reminder file after it has run. This is equivalent to
Xperforming a "touch" of the file after running REMIND.
X
XAlso, the MS-DOS version does not queue AT reminders for timed activation.

XREMIND version 2.2 for UNIX
X
XFirst, read the files COPYRIGHT and WHATSNEW.22
X
XBefore compiling the software, check if it includes patches. These
Xare files called patch.xx. If there are patches, apply them all by typing
X
Xcat patch.* | patch
X
XThe Makefile is very simple and naive. It is set up for a BSD system.
XIf you have a SYSV system, edit the Makefile. Comment out the line
Xwhich reads:
X
X CFLAGS= -O -DUNIX
X
Xand uncomment the line which reads:
X
X CFLAGS= -O -DUNIX -DSYSV
X
XTo compile REMIND, just go to the source directory and type "make".
XThis creates the executable file "remind". You can type "make CC=gcc"
Xif you want to use the Gnu C Compiler.
X
XREMIND has been compiled on Sun3s and Sun4s under Sun OS 4.0. A previous
Xversion compiled successfully on a Xenix system. REMIND should compile
Xon most systems, as it makes very few system calls.
X
XOnce remind has been compiled, install it in your favourite system directory.
XThe manual is in the file "remind.1". You can install it in the appropriate
Xman page directory. Remember to change the file suffix if you install it
Xin the "l" (local) or "n" (new) directory.
X
XTwo shell scripts, "remind-all.csh" and "remind-all.sh" are provided. These
Xallow automatic mailing of reminders to all users who create a $HOME/.reminders
Xfile. These two scripts are equivalent; one is a "sh" script and the other
Xis a "csh" script. Pick the one you want to use, and follow the instructions
Xin the opening comments of the script.

XA BRIEF HISTORY OF REMIND:
X
XVersion 1.0 - never publicly released.
X
XVersion 2.0 - first public release. Included advanced date specifications,
Xcharacter substitution, and the RUN keyword.
X
XVersion 2.1 - Added the "repeat" token for repeating reminders with a period
Xother than 7 days. Also fixed some bugs from version 2.0
X
XVersion 2.2 - Added the AT keyword, the timed reminders daemon, and the
Xcalendar facility.
