 The creation of objects is a little different in Python than in C:
 instead of the `current form' maintained by the library to which new
 FORMS objects are added, all functions that add a FORMS object to a
 form are methods of the Python object representing the form.
 Consequently, there are no Python equivalents for the C functions
-\code{fl_addto_form} and \code{fl_end_form}, and the equivalent of
-\code{fl_bgn_form} is called \code{fl.make_form}.

 Watch out for the somewhat confusing terminology: FORMS uses the word
 \dfn{object} for the buttons, sliders etc. that you can place in a form.
 In Python, `object' means any value.  The Python interface to FORMS
 introduces two new Python object types: form objects (representing an
 entire form) and FORMS objects (representing one button, slider etc.).

 There are no `free objects' in the Python interface to FORMS, nor is
 there an easy way to add object classes written in Python.  The FORMS
 interface to GL event handling is available, though, so you can mix
 FORMS with pure GL windows.
