+/**
+ * @short This class provides the functionality to download and upload "new stuff".
+ *
+ * Applications have to subclass KNewStuff, implement the pure virtual functions
+ * and link to against libknewstuff.
+ *
+ * By calling download() the download process is started which means that a list
+ * of "providers" is fetched from a "master server", information about new stuff
+ * is collected from the providers and presented to the user. Selected entries
+ * get downloaded and installed to the application. The required functions to
+ * install new stuff are provided by implementing install(). The location where
+ * the downloaded files are stored can be customized by reimplementing
+ * downloadDestination().
+ *
+ * By calling upload() the upload process is started which means the user has to
+ * select a provider from the list fetched from the master server and to put in
+ * information about the entry to be uploaded. Then the file to be uploaded is
+ * fetched from the application by calling createUploadFile() and transfered to
+ * the upload destination specified in the provider list.
