rs makes it easy to remember! (At least for me :-)

If you like it, use it.  If you don't like it loose it!  :-)

What else do you do with a rainy weekend?

	XThis directory contains the source and manual entry for the rs program.
	XSee the manual entry for more information on the use of rs.
	XThe rs program was written under and for BSD 4.2
	X
	XTo Install:
	X
	X1)	Look at rs.c and change any #defines needed.
	X	Defaults:
	X
	X		CALENDAR  "/calendar"		users calendar file.
	X		RSFILE	  "/.reminders"		users reminder file.
	X		RSNOTES	  "/.rsnotes"		users notes    file.
	X
	X		All of the above files are looked for in the users HOME dir.
	X
	X		LPR		"/usr/ucb/lpr"	location of lpr command.
	X		VI		"/usr/ucb/vi"	location and def. of editor.
	X
	X		MAXLINES	500		Max. number of lines (reminders)
	X		MAXLEN		256		Max. len of a single line.
	X
	X	If your /tmp directory is somewhere else, change rstmp.
	X	Default:	char rstmp[] = "/tmp/rsXXXXX"
	X
	X2)	Look at the Makefile and change target directory for the rs executable 
	X	and the manual entry if you wish.
	X
	X	Defaults:
	X
	X		DEST  = /usr/local		rs program >> /usr/local
	X		MDEST = /usr/man/manl		rs manual  >> /usr/man/manl
	X
	X3)	Run 'make install' which will make and install the executables and the
	X	manual entries.
	X	If you want to compile the rs program in the current directory,
	X	run 'make program'.

	X.SH NAME
	Xrs \ - reminder system
	X.SH SYNOPSIS
	X.B rs
	X[ \-Aacknpv ] [ \-s
	X.I string
	X] [ -d # ] [ -d #-# ]
	X.SH DESCRIPTION
	X.I rs
	Xis a personal reminder system.  Reminders that you have added can be displayed
	Xevery time you log into the system By placing the
	X.I rs
	Xcommand in your
	X.I .login
	Xfile.  The reminder system includes two reminder files,
	Xone for reminders and one for notes, plus an alternate reminder file that is
	Xuser defined by the environment variable
	X.I RSALT.
	X.TP
	X.I Options:
	X.TP
	X.I rs
	Xwith no options will output reminder list to terminal.
	X.TP
	X.B \-A
	Xwork with
	X.I alternate
	Xreminder file.  The name of the alternate file is user
	Xdefined in the
	X.I RSALT
	Xenvironment variable.
	X.TP
	X.B \-a
	Xadd reminder(s)/note(s)/alternate(s).  User is prompted to add reminder(s)/note(s)/alternate(s).
	X.TP
	X.B \-c
	Xadd reminder(s) to calendar system.  User is prompted to add calendar reminder(s).
	Xsee
	X.I calendar(1).
	X.TP
	X.B \-d
	Xdelete reminder(s)/note(s)/alternate(s).  Followed by a number or numbers, 
	X.I rs
	Xwill delete
	Xthe specified reminder(s)/note(s)/alternate(s).  More than 1 number may be placed on the same
	Xcommand line separated by blanks.  A range of numbers may also be specified
	Xwith the format #-#.
	X.TP
	X.B \-k
	Xkill all reminders/notes/alternates.
	X.TP
	X.B \-n
	Xwork on
	X.I notes
	Xreminder file.
	X.TP
	X.B \-p
	Xprint reminders/notes/alternates. (Does an
	X.I lpr
	Xof reminder file.)
	X.TP
	X.B \-s
	Xsearch for reminders/notes/alternates that match the given string.
	X.TP
	X.B \-v
	Xedit reminders/notes/alternates with
	X.I vi.
	X.PP
	XMore than one option may follow a single '-'.
	X.br
	XExample:
	X
	X.br
	X	rs -na		The command for "add note".
	X
	X.PP
	X.I rs
	Xlooks in the environment variable
	X.I RSINIT
	Xto determine what to do after additions/deletions to a reminder/note/alternate
	Xfile.  For example, if you prefer to view your reminders/notes/alternates after
	Xadditions/deletions, the
	X.I csh
	Xcommand
	X.I "setenv RSINIT 'aAdD'"
	Xwould cause
	X.I rs
	Xto display your reminders/notes/alternates after additions/deletions.  The
	Xabove command sequence may be placed in your
	X.I .login
	Xfile.
	X.br
	Xa & d = display reminders after additions/deletions.
	X.br
	XA & D = display notes/alternates/calendar after additions/deletions.
	X.PP
	XReminders/notes/alternates may be from 1 to 255 characters long.  If a reminder is longer than
	X80 characters (1 line),
	X.I rs
	Xwill do automatic word wrapping.  To add a reminder/note/alternate longer than
	X80 characters, type in the entire reminder/note/alternate and end with a single
	Xcarriage return. Do
	X.I not
	Xinsert carriage returns before the end of a
	Xreminder/note/alternate.  A single carriage return
	X.I always
	Xindicates the
	X.I end
	Xof a reminder.
	X.SH EXAMPLES
	Xrs -d 1 5 8	delete reminders 1, 5, 8.
	X.TP
	Xrs -n -d 1-5 8	delete notes 1, 2, 3, 4, 5, 8.
	X.TP
	Xrs -k		kill all reminders.
	X
	X.SH EXAMPLE USE OF ALTERNATE REMINDER FILE
	X.PP
	X
	XIf you would like to have a list of phone numbers that can be accessed by the
	Xreminder system, you could do the following:
	X.PP
	XSet the
	X.I RSALT
	Xenvironment variable to
	X.I phone-numbers
	Xby including the following command line in your
	X.I .login
	Xfile:
	X.TP
	X.I "     setenv RSALT 'phone-numbers'"
	X.TP
	XUse the reminder system command:
	X.TP
	X.I "     rs -A [options]"
	X.TP
	Xto work on the phone-numbers reminder file.
	X.SH EXAMPLE COMMANDS FOR PHONE-NUMBERS REMINDER FILE
	X.TP
	Xrs \-A \-a
	XAdd phone numbers to the phone-numbers reminder file.
	X.TP
	Xrs \-A \-s Joslyn   Search for Joslyn's phone number.
	X.TP
	Xrs \-A \-v          Edit phone-numbers with vi.
	X.TP
	Xrs \-A \-p          Print phone-numbers on the line printer.
	X.TP
	Xrs \-A \-d 1        Delete the first line from phone-numbers.
	X.SH FILES
	X~.reminders     users reminders.
	X.br
	X~.rsnotes       users notes.
	X.br
	X/tmp/.rs*       used during reminder deletion.
	X.br
	X~.?             other reminder file(s) defined by
	X.I RSALT.

	X.SH BUGS
	XThe
	X.I auto-wrap
	Xfeature can be fooled since
	X.I rs
	Xlooks for blanks between words to split lines.  If a word is longer than 75
	Xcharacters,
	X.I rs
	Xwill NOT break the line up properly.  Strange things will occur!
