== The deployments' XO Operating System ==

Dextrose is a Sugar distribution for the XO-1 and XO-1.5 jointly developed by [http://activitycentral.org Activity Central], [http://paraguayeduca.org/ Paraguay Educa], [http://www.ceibal.edu.uy/ Plan Ceibal] and [http://sugarlabs.org Sugar Labs] in collaboration with the OLPC and Sugar community.

Our focus is stability and usability in the classroom, but we've also merged some
new features contributed by deployments and freelance contributors.
