This overlay contains curated unmodified(*) Gentoo packages that are part of the Chromium OS build and are exact copies of upstream Gentoo packages. For information on updating ebuilds here, see: http://dev.chromium.org/chromium-os/gentoo-package-upgrade-process Note: While there are tools to help automate importing of updates, the overall process is not fully automatic: a developer must initiate the process as well as run all the proper tests themselves (trybots/etc...). Licensing information can be found in the respective files, so consult them directly, or refer to the upstream Gentoo copy: http://sources.gentoo.org/gentoo-x86/ (*) The spirit of this repo is that any package may be blindly blown away when upgrading to a newer version. So we sometimes allow minor changes to be merged as long as that spirit is maintained. We also munge the ebuild to set KEYWORDS="*" when importing. The upstream values have no bearing on our usage or porting efforts.
