#
#  Purpose:  CGI script to generate frame set for selecting a folder from the user's
#	     defined collections in webpine-lite pages.  the idea is that this
#            page specifies a frameset that loads a "header" page 
#            used to keep the servlet alive via
#            periodic reloads and a "body" page containing static/form
#            elements that can't/needn't be periodically reloaded or
#            is blocked on user input.

#  Input:
set frame_vars {
  {onselect	""	main}
  {oncancel	""	main}
  {target	""	""}
  {controls	""	0}
}

#  Output:
#

## read vars
foreach item $frame_vars {
  if {[catch {cgi_import [lindex $item 0].x}]} {
    if {[catch {eval WPImport $item} errstr]} {
      error [list _action "Impart Variable" $errstr]
    }
  } else {
    set [lindex $item 0] 1
  }
