=head1 NAME

examples/mops/mops.c - Calculate M ops/s

=head1 SYNOPSIS

    % python examples/mops/mops.py

=head1 DESCRIPTION

A Python implementation of the F<examples/mops/mops.pasm> example
program, for speed comparisons.

Calculates a value for M ops/s (million operations per second) using
integer arithmetic.

Prints out:

=over 4

=item * the number of look iterations, 

=item * the estimated number of ops performed,

=item * the elapsed time, and 

=item * the number of M op/s.
