.SH NAME

concat \- Join lists together

.SH SYNOPSIS

\fBconcat\fI \fR?\fIarg arg ...\fR?

.SH DESCRIPTION

.PP

This command treats each argument as a list and concatenates them

into a single list.

It also eliminates leading and trailing spaces in the \fIarg\fR's

and adds a single separator space between \fIarg\fR's.

It permits any number of arguments.  For example,

the command

.CS

\fBconcat a b {c d e} {f {g h}}\fR

.CE

will return

.CS

\fBa b c d e f {g h}\fR

.CE

as its result.

.PP

If no \fIarg\fRs are supplied, the result is an empty string.

.SH KEYWORDS
