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, flattening them in  the  process  (so  giving  the
       following interactive session):

              % concat a b {c d e} {f {g h}}
              a b c d e f {g h}

       it will also concatenate things that are not lists, as can be seen from this session:

              % concat " a b {c   " d "  e} f"
              a b {c d e} f

       Note  also that the concatenation does not remove spaces from the middle of values, as can
       be seen here:

              % concat "a   b   c" { d e f }
              a   b   c d e f

       (i.e., there are three spaces between each of the a, the b and the c).
