Structure overview of the KDE libraries

Libraries by name

• kdecore
  The kdecore library is the basic application framework for every KDE based program. It provides access to the configuration system, command line handling, icon loading and manipulation, some special kinds inter-process communication, file handling and various other utilities.
• kdeui
  The kdeui library provides many widgets and standard dialogs which Qt doesn't have or which have more features than their Qt counterparts. It also includes several widgets which are subclassed from Qt ones and are better integrated with the KDE desktop by respecting user preferences.
• kio
  The kio library contains facilities for asynchronous, network transparent I/O and access to mimetype handling. It also provides the KDE file dialog and its helper classes.
• kjs
  The kjs library provides an implementation of JavaScript.
• khtml
  The khtml library contains the KHTML part, a HTML browsing widget, DOM API and parser, including interfaces to Java and JavaScript.
