Jambo OpenOffice (Hello OpenOffice) was an open source office suite based on OpenOffice.org written for Swahili speakers and runs on Linux and Microsoft Windows.
It was developed by Kilinux and the first major project release took place in December 2004 as JambOO.o based on OpenOffice.org 1.1.3.
The project seems to have been inactive since 2005 and the plans to update and sync Jambo OpenOffice to OpenOffice.org 2 were never finished.
