the leading open-source office software suite for word processing, spreadsheets, presentations, graphics, databases and more. It is available in many languages and works on all common computers. It stores all your data in an international open standard format and can also read and write files from other common office software packages. It can be downloaded and used completely free of charge for any purpose.The Impress portion will enable you to create your own multi-media presentations. I created an adequate one, without too much difficulty, and I expect, with a little more practice I could create one that is REALLY good! And the only thing it cost me, was a little time!
