=head1 NAME

Crypt::RSA::Debug - Debug routine for Crypt::RSA.

=head1 SYNOPSIS

    use Crypt::RSA::Debug qw(debug);
    debug ("oops!");

The module provides support for the I method of debugging!

=head1 FUNCTION

=over 4

=item B String

Prints B on STDOUT, along with caller's function name and line number.

defaults to 0. Callers can use the debuglevel facility by
comparing $Crypt::RSA::DEBUG to the desired debug level before
generating a debug statement.
