KDE Kontact is a personal information manager and groupware software suite for KDE. It unites mature and proven applications including KMail, KAddressBook, KOrganizer, KNode, and KNotes.
Consequently, the package supports calendars, contacts, notes, to-do lists, news, and email. It uses KParts to embed the various applications into the container application.
The components of KDE Kontact are tailored to work well with each other. This results in features such as intuitive drag-and-drop between appointment handling, task lists and contacts.
