Apache OpenOffice is comprised of six personal productivity applications: a word processor (and its web-authoring component), spreadsheet, presentation graphics, drawing, equation editor, and database. OpenOffice is released on Windows, Solaris, Linux and Macintosh operation systems, with more communities joining, including a mature FreeBSD port. OpenOffice is localized, supporting over 110 languages worldwide.
