High Quality Content by WIKIPEDIA articles! Xenocara is the OpenBSD build infrastructure for the project`s customised X.Org 7.4. Until release 6.9, X.Org used imake but recent modularised versions have switched to GNU autotools. Xenocara uses BSD make and is designed to ease building and maintenance of modularised X.Org within the OpenBSD CVS tree. It first appeared with OpenBSD 4.2, released on 1 November 2007.
