+.SH NAME
+append \- Append to variable
+.SH SYNOPSIS
+\fBappend \fIvarName \fR?\fIvalue value value ...\fR?
+.BE
+
+.SH DESCRIPTION
+.PP
+Append all of the \fIvalue\fR arguments to the current value
+of variable \fIvarName\fR. If \fIvarName\fR doesn't exist,
+it is given a value equal to the concatenation of all the
+\fIvalue\fR arguments.
+This command provides an efficient way to build up long
+variables incrementally.
+For example, ``\fBappend a $b\fR'' is much more efficient than
+``\fBset a $a$b\fR'' if \fB$a\fR is long.
+
+.SH KEYWORDS
+append, variable
