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: con-
       cat " 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).
