DESCRIPTION
       The ::javascript package provides commands that generate HTML and  Java
       Script  code.   These commands typically return an HTML string as their
       result.  In particular, they do not output their result to stdout.


       ::javascript::makeSelectorWidget id leftLabel leftValueList rightLabel
       right- ValueList rightNameList ?length? ?minWidth?
              Construct HTML code to create a dual-multi-selection megawidget.
              This  megawidget  consists  of  two side-by-side multi-selection
              boxes separated by a left arrow and a right arrow  button.   The
              right  arrow  button moves all items selected in the left box to
              the right box.  The left arrow button moves all  items  selected
              in the right box to the left box.  The id argument is the suffix
              of all HTML objects in this megawidget.  The leftLabel  argument
              is  the  text  that  appears  above the left selection box.  The
              leftValueList argument is the values of items in the left selec-
              tion  box.   The leftNameList argument is the names to appear in
              the left selection box.  The rightLabel  argument  is  the  text
              that  appears above the right selection box.  The rightValueList
              argument is the values of items in the right selection box.  The
              rightNameList  argument  is  the  names  to  appear in the right
              selection box.  The length argument  (optional)  determines  the
              number  of  elts  to show before adding a vertical scrollbar; it
              defaults to 8.  The minWidth argument (optional) is  the  number
              of spaces to determine the minimum box width; it defaults to 32.

              Create an HTML submit button that resets a hidden field for each
