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).
