#  fr_flags.tcl
#
#  Purpose:  CGI script to generate frame set for flag setting
#	     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 {
  {uid	"Missing UID"}
}

#  Output:
#

# inherit global config
source ./alpine.tcl
source cmdfunc.tcl
