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.
