DESCRIPTION

       stfl is a library which implements a curses-based widget set for text terminals.  A special language (the
       Structured Terminal Forms Language) is used to describe stfl GUIs. The language is designed  to  be  easy
       and  fast  to write so an application programmer does not need to spend ages fiddling around with the GUI
       and can concentrate on the more interesting programming tasks.

       stfl_create
              Parses the the stfl description text passed as parameter and returns a form handler.

       stfl_free
              Free all resources associated with this form

       stfl_run
              Return the next event. If no more prior generated events are waiting display the form and  process
              one input character.

       stfl_reset
              The  stfl_run() function automatically activates ncurses. This function can be used to explicitely
              switch back to normal text  mode.  In  some  languages  this  is  automatically  done  on  program
              termination.

       stfl_get
              Returns  the  current  value  of  the  specified  variable.  When the variable does not exist this
              function returns an undefined value.

       stfl_set
              This sets the specified variable to the specified value.

       stfl_get_focus
              Returns the name of the widget which currently has the focus or an undefined value when the widget
              having the focus has no name.

       stfl_set_focus
              Set the focus to the specified widget.

       setfl_quote
              Quote the text so it can be savely used as variable value in stfl code.

       stfl_dump
              Return the subtree starting with the widget specified in the 2nd parameter as stfl code fragment.

       stfl_modify
              Import the stfl code specified in the 4th parameter to an existing form. The 2nd parameter is used
              to specify a widget which is used as starting point for the modification. The 3rd parameter  is  a
              string specifying how the new stfl code should be added to the widget tree.

       stfl_lookup
              Lookup  widgets  in  the form using a path and optionally assign a new name.  This function is not
              implemented yet.

       stfl_error
              Set the error handling algorithm.
