NAME
       concat - Join lists together

SYNOPSIS
       concat ?arg arg ...?


DESCRIPTION
       This  command  joins  each  of its arguments together with
       spaces after trimming leading  and  trailing  spaces  from
       each  of  them.   If all the arguments are lists, this has
       the same effect as concatenating them into a single  list.
       It permits any number of arguments.  For example, the com-
       mand
              concat a b {c d e} {f {g h}}
       will return
              a b c d e f {g h}
       as its result, and
              concat " a b {c   " d "  e} f"
       will return
              a b {c d e} f
       as its result.

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