LibreOffice is a free and open source office suite, developed by The Document Foundation. The LibreOffice suite comprises programs to do word processing, spreadsheets, slideshows, diagrams, maintain databases, and compose math formulae. It is designed to be compatible with other major office suites, including Microsoft Office, though some Microsoft Office layout features and formatting attributes are handled differently or are unsupported. LibreOffice is available in over 30 languages and for a variety of computing platforms, including Microsoft Windows, Mac OS X 10.4 Tiger or newer, and Linux. It is the default office suite of most popular Linux distributions.
