-# How to contribute #
-
-We'd love to accept your patches and contributions to this project.  There are
-a just a few small guidelines you need to follow.
-
-
-## Contributor License Agreement ##
-
-Contributions to any Google project must be accompanied by a Contributor
-License Agreement.  This is not a copyright **assignment**, it simply gives
-Google permission to use and redistribute your contributions as part of the
-project.
-
-  * If you are an individual writing original source code and you're sure you
-    own the intellectual property, then you'll need to sign an [individual
-    CLA][].
-
-  * If you work for a company that wants to allow you to contribute your work,
-    then you'll need to sign a [corporate CLA][].
-
-You generally only need to submit a CLA once, so if you've already submitted
-one (even if it was for a different project), you probably don't need to do it
-again.
-
-[individual CLA]: https://developers.google.com/open-source/cla/individual
-[corporate CLA]: https://developers.google.com/open-source/cla/corporate
-
-Once your CLA is submitted (or if you already submitted one for
-another Google project), make a commit adding yourself to the
-[AUTHORS][] and [CONTRIBUTORS][] files. This commit can be part
-of your first [pull request][].
-
-[AUTHORS]: AUTHORS
-[CONTRIBUTORS]: CONTRIBUTORS
-
-
-## Submitting a patch ##
-
-  1. It's generally best to start by opening a new issue describing the bug or
-     feature you're intending to fix.  Even if you think it's relatively minor,
-     it's helpful to know what people are working on.  Mention in the initial
-     issue that you are planning to work on that bug or feature so that it can
-     be assigned to you.
-
-  1. Follow the normal process of [forking][] the project, and setup a new
-     branch to work in.  It's important that each group of changes be done in
-     separate branches in order to ensure that a pull request only includes the
-     commits related to that bug or feature.
-
-  1. Do your best to have [well-formed commit messages][] for each change.
-     This provides consistency throughout the project, and ensures that commit
-     messages are able to be formatted properly by various git tools.
-
-  1. Finally, push the commits to your fork and submit a [pull request][].

-// CycleClock
-//    A CycleClock tells you the current time in Cycles.  The "time"
-//    is actually time since power-on.  This is like time() but doesn't
-//    involve a system call and is much more precise.
-//
-// NOTE: Not all cpu/platform/kernel combinations guarantee that this
-// clock increments at a constant rate or is synchronized across all logical
-// cpus in a system.
-//
-// If you need the above guarantees, please consider using a different
-// API. There are efforts to provide an interface which provides a millisecond
-// granularity and implemented as a memory read. A memory read is generally
-// cheaper than the CycleClock for many architectures.
-//
-// Also, in some out of order CPU implementations, the CycleClock is not
-// serializing. So if you're trying to count at cycles granularity, your
-// data might be inaccurate due to out of order instruction execution.
