DESCRIPTION

       This  package  provides a dialog which consists of 2 listboxes, along with buttons to move
       items between them and reorder the right list.

       ::swaplist::swaplist pathName variable completeList selectedList ?options?
              Creates a dialog which presents the user  with  a  pair  of  listboxes.  Items  are
              selected  by  using the buttons to move them to the right list. The contents of the
              right list are put in the variable upon closure of the dialog.  The command returns
              a  boolean indicating if the user pressed OK or not. If -geometry is not specified,
              the dialog is centered in its parent toplevel unless its parent is . in which  case
              the dialog is centered in the screen.

              Options:

              -embed if  this flag is supplied, the procedure will create a swaplist widget named
                     pathName, with the variable set as  the  listvariable  for  the  right  side
                     listbox.  This  flag  will  also  cause the -title and -geometry flags to be
                     ignored.

              -reorder
                     boolean specifying if buttons allowing the user to change the order  of  the
                     right listbox should appear or not. defaults to true

              -title sets the title of the dialog window. defaults to "Configuration"

              -llabel
                     sets the heading above the left list. defaults to "Available:"

              -rlabel
                     sets the heading above the right list. defaults to "Selected:"

              -lbuttontext
                     sets the text on the "move left" button. defaults to "<<"

              -rbuttontext
