OpenOffice.org
From Docunext Technology Wiki
OpenOffice.org is an open source office productivity suite of software packages. It includes:
- oowriter for word processing
- oocalc for spreadsheet
- ooimpress for presentations
- oodraw for graphics
There are some other tools it includes, but those are the ones I use.
