REMIND is a sophisticated reminder service, with many more features than
the Unix calendar command. It includes the ability to specify holidays,
advance warning of reminders, sophisticated date specifications, and
the ability to format output in a convenient way.
REMIND was written originally for MS-DOS and then ported to Unix.
It has been compiled on a Sun 3 and a Sun 4, as well as under Microsoft
C (5.1) for MS-DOS. It should work with minimal modifications on most
Unix systems.

XREMIND 2.0 for MS-DOS
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
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.

XREMIND version 2.0 for UNIX
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
XThe Makefile is very simply and naive.
X
XREMIND has only been compiled on Sun3s and Sun4s under Sun OS 4.0.
XHowever, it makes very few system calls and should work on most BSD systems.
XIt shouldn't take too much hacking to get REMIND to work on almost any
Xsystem. The troublesome files are main.c which gets the current system
Xdate, and files.c which opens and closes files.
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.
