OpenOffice.org gives you everything you’d expect in office software. You can create dynamic documents, analyse data, design eye-catching presentations, produce dramatic illustrations, and open up your databases. You can publish your work in Portable Document Format (.pdf), and release your graphics in Flash (.swf) format – without needing any additional software. OpenOffice.org is now available for more users than ever, with support for complex text layout (CTL) languages (such as Thai, Hindi, and Hebrew) and vertical writing languages.
OpenOffice.org is both an Open Source product and a project. The product is a multi-platform office productivity suite. It includes the key desktop applications, such as a word processor, spreadsheet, presentation manager, and drawing program, with a user interface and feature set similar to other office suites. Sophisticated and flexible, OpenOffice.org also works transparently with a variety of file formats, including those of Microsoft Office.
