You can define your own substitution sequences in addition to the built-in
ones as follows: If you define a function named \fBsubst_\fIname\fB(alt, date, time)\fR, then the sequence \fB%{name}\fR calls the function with \fBalt\fR
set to 0 and \fBdate\fR and \fRtime\fR to the trigger date and time,
respectively. The \fB%{name}\fR sequence is replaced with whatever the
function returns. The sequence \fB%*{name}\fR is similar, but calls
the function with \fBalt\fR set to 1.
.PP
If you use a \fB%{name}\fR sequence and the function \fBsubst_\fIname\fR is
not defined or returns an error, then \fB%{name}\fR is replaced with the
empty string.
