Overview
Nano-X's origin is with NanoGUI. NanoGUI was created by Alex Holden by taking David Bell's mini-X server and Alan Cox's modifications and adding client/server networking. Gregory Haerr then took interest in the NanoGUI project and began making extensive enhancements and modifications to NanoGUI. Around version 0.5, Gregory Haerr added support for multiple API's, and began distributing Microwindows. In Microwindows 0.84, all previous NanoGUI changes were incorporated and since then has been the combined NanoGUI/Microwindows distribution. In January 2005, the system changed its name to the Nano-X Window System, with a planned first release as v0.91.
