=head1 NAME
In the name section, all the functions described shoud be enumerated. This will also make it much simpler to generate softlinks name like each function to man-pages containing the info.

=head1 DESCRIPTION
BN_zero(), BN_one() and BN_set_word() set B<a> to the values 0, 1 and
B<w> respectively. BN_zero() and BN_one() are macros.
BN_value_one() returns a B<BIGNUM> constant of value 1. This constant
is useful for use in comparisons and assignment.
BN_get_word() returns B<a>, if it can be represented as an unsigned
long.
=head1 RETURN VALUES
BN_get_word() returns the value B<a>, and 0xffffffffL if B<a> cannot
be represented as an unsigned long.

BN_one(), BN_set_word() and the deprecated version of BN_zero()
return 1 on success, 0 otherwise.

The preferred version of BN_zero() never fails and returns no value.

Someone might change the constant.

If a B<BIGNUM> is equal to 0xffffffffL it can be represented as an
unsigned long but this value is also returned on error.
