DESCRIPTION
       The list argument must be a valid Tcl list.  This command returns the
       string formed by joining all of the elements of list together with
       joinString separating each adjacent pair of elements.  The joinString
       argument defaults to a space character.

EXAMPLES
       Making a comma-separated list:

              set data {1 2 3 4 5}
              join $data ", "
                   -> 1, 2, 3, 4, 5

       Using join to flatten a list by a single level:

              set data {1 {2 3} 4 {5 {6 7} 8}}
              join $data
                   -> 1 2 3 4 5 {6 7} 8
