Apache Whirr moved into the Attic in March 2015. Apache Whirr was a set of libraries for running cloud services and deploying clusters.
The website, downloads and issue tracker all remain open, though the issue tracker is read-only. See the website at http://whirr.apache.org for more information on Whirr.
Note that instructions on how to obtain and build the source are found on the wiki and not the website: https://cwiki.apache.org/confluence/display/WHIRR/How+To+Contribute.
As with any project in the Attic - if you should choose to fork Whirr outside of Apache, please let us know so we can link to your project.
Archived versions of the Whirr may be downloaded from the Apache Archives.
