.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.
