NeoOffice is a fully-featured set of office applications (including word processing, spreadsheet, presentation, vector drawing, database, and macro functionality) for Mac OS X. It can import, edit, and exchange documents with other popular office programs such as Microsoft Office.
NeoOffice is focused on making OpenOffice.org a better Mac OS X citizen, with dozens of standard Mac features not found in OpenOffice.org. NeoOffice does NOT require the X11 windowing system.
