NAME
       concat - Join lists together

SYNOPSIS
       concat ?arg arg ...?


DESCRIPTION
       This   command   treats   each  argument  as  a  list  and
       concatenates them into a single list.  It also  eliminates
       leading and trailing spaces in the arg's and adds a single
       separator space between arg's.  It permits any  number  of
       arguments.  For example, the command
              concat a b {c d e} {f {g h}}
       will return
              a b c d e f {g h}
       as its result.

       If no args are supplied, the result is an empty string.
