/*
This program contains a simple micro-benchmark for a Disruptor [1] like
event buffer (or at least what I think that Disruptor might be). There
isn't any kind of API yet and this test is currently limited to a
single producer - single consumer architecture, but generally the
architecture of Disruptor is also well suited for multiple producers and
consumers.

cross-platform git pre-commit hook for puppet repos
#!/usr/bin/env ruby
# An example cross-platform (Linux, Windows, Mac, etc.)
# pre-commit hook script to verify what is about to be committed.
# Called by "git commit" with no arguments. The hook should
# exit with non-zero status after issuing an appropriate message if
# it wants to stop the commit.
# To enable this hook:
# - save this file as <path-to-git-clone>/.git/hooks/pre-commit
