Despite being small, X15 already supports quite a few configurations, such as i386 (32-bits x86, with or without PAE), amd64 (also known as x86_64) and a bunch of test modules. It’s very likely to support more in the future, so I decided to take some time and try Buildbot, a continuous integration framework, to automate builds with varying options. A link to the web interface is now in the main menu bar of the web site.
