TEXT ;Custom Date Due help text.
 ;;The general form for a Custom Date Due string is:
 ;; FUNCTION(ARG1,ARG2,...,ARGN)
 ;;where FUNCTION is MAX_DATE or MIN_DATE and the arguments have the form
 ;;M+FREQ where M is a finding number and FREQ is a number followed by
 ;;D for days, M for months, or Y for years.
 ;;Here is an example:
 ;; MAX_DATE(1+6M,3+1Y)
 ;;This will take the date of finding 1 and add 6 months, the date of finding 3
 ;;and add 1 year and set the date due to the maximum of those two dates.
