KOffice 2.1
KOffice is an integrated office suite for the KDE (K Desktop Environment) consisting of several applications like for examples a word processor (KWord) and a spread sheet (KSpread). Based on the KParts component model, KOffice offers a lot of interoperability between all its components. For example, you can embed every KOffice component into another component (for example a KSpread table into your KWord document.)
