Most functions are literal translations of their C equivalents,

library are defined in module \code{FL} described below.

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
button are methods of the Python object representing the form.

Consequently, there are no Python equivalents for the C functions

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
