What is TravisCI?
Travis CI is a hosted, distributed Continuous Integration service used to build and test software projects hosted at GitHub. Travis CI is integrated with GitHub pull requests and supports all programming languages that can be built into docker images, making it very handy to setup.
What is Gentoo?
Gentoo is a totally free Linux distribution. It uses the latest development tools and software technologies and is dedicated to quality rather than blindly following traditional usage patterns with binary packages and config files. Every part of Gentoo, including installation images, is free software; most of the source code is available to whoever wants it. Gentoo has been developed in an entirely open process, in which technical choices are made via discussion in email forums and IRC channels rather than by secretive members of some elite development cabal. Each package in Gentoo has its own maintainer who decides whether or not to include it; you are welcome to volunteer to Gentoo.
