OpenLP is an open source worship presentation program written specially for churches. It can display songs, Bible verses, videos, images and even PowerPoint presentations if PowerPoint XP or higher is installed.
OpenLP keeps a database of songs, which you can add, edit and update. You can import songs from other openlp.org songs databases or even other presentation applications.
OpenLP features a completely translatable interface, so that you can have openlp.org in your own langauge.
OpenLP is in use in churches all around the world, from the USA to the UK to Indonesia, from Finland to Canada to South Africa, from Australia to the Brazil.
