In its current form, KDE provides, apart the essential desktop component applications, a suite of powerful office programs, known to world under the name KOffice.
KOffice is based on the KDE DCOP/KParts technologies. It contains presently: a word processor with desktop publishing capabilities (KWord), a spreadsheet application (KSpread) and accompanying Charting program (KChart), a presentation program (KPresenter) and a vector drawing program (KIllustrator). Tying things together is the KOffice Workspace, an integrated shell to ease the use of the KOffice components in conjunction with each other. Additional components include an email client, a news reader, and a powerful PIM (Personal Information Manager - an organizer).
While some of those components are still in alpha developement others are already extremely powerful. For example, KPresenter, KDE's presentation application was successfully used at the 5th international Linux congress in Cologne, Germany to deliver a KDE presentation.
We would like to invite you to learn more about KDE and KOffice.
