/*
 * a set of macros to aid in creating beautiful reminders with remind(1)
 * 
 *	some points to note -
 *
 *	    getting certain characters into the final output is hard -
 *		instead, use the following substitutions
 *		    for '	    use 
 ( character \001 )
 *		    for ;	    use  ( character \002 )
 *		    for \	    use  ( character \003 )
 *		    for newline	    use ;
 *
 *	    use DOSHOWTIME to incorporate the output of a command
 *		executed at the time the reminder appears on the screen
 *	    use DOPOSTTIME for commands to be executed at the time
 *		"remind" is run
 *
 *	    HEAD centers the text, and underlines it with **'s
 *	    COMMENT is useful for text that should not appear in the
 *		reminder, but is needed to flag a time or date
 *	    PAD fills the remainder of the line with spaces, so that the
 *		dialog will in fact be the right width - use it at least
 *		once if using centered text
 *
 *	    NL causes a new line
 *	    RMARG, LMARG and MARGINS set the margin positions
 *
 *	    use ;; for a new paragraph
