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 white-space 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; if no args
       are supplied, the result is an empty string.

EXAMPLES

       Although concat will concatenate lists (so the command:
	      concat a b {c d e} {f {g h}}
       will return "a b c d e f {g h}" as its result), it will also concatenate things that are not lists, and hence the command:
	      concat " a b {c	" d "  e} f"
       will return "a b {c d e} f" as its result.

       Note that the concatenation does not remove spaces from the middle of its arguments, so the command:
	      concat "a   b   c" { d e f }
       will return "a	b   c d e f" (i.e. with three spaces between the a, the b and the c).
