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 command
              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.
