+.SH NAME
+lrepeat \- Build a list by repeating elements
+.SH SYNOPSIS
+\fBlrepeat \fInumber element1 \fR?\fIelement2 element3 ...\fR?
+.BE
+.SH DESCRIPTION
+.PP
+The \fBlrepeat\fP command creates a list of size \fInumber * number of
+elements\fP by repeating \fInumber\fR times the sequence of elements
+\fIelement1 element2 ...\fR.  \fInumber\fP must be a positive integer,
+\fIelementn\fP can be any Tcl value.  Note that \fBlrepeat 1 arg ...\fR
+is identical to \fBlist arg ...\fR, though the \fIarg\fR is required
+with \fBlrepeat\fR.
+.SH EXAMPLES
+.CS
+lrepeat 3 a  => a a a
+lrepeat 3 [lrepeat 3 0] => {0 0 0} {0 0 0} {0 0 0}
+lrepeat 3 a b c => a b c a b c a b c
+lrepeat 3 [lrepeat 2 a] b c => {a a} b c {a a} b c {a a} b c
