// dataprotocol.* interprets the following defines

//		kioslave
// TESTKIO: define for test-driving
// Both defines are mutually exclusive. Defining none of them compiles
// DataProtocol for internal usage within libkiocore.

/* Wondering what this is all about? Leo explained it to me:
 *
 * That's simple, you can compile it into a standalone executable that is
 * registered like any other kioslave.
 *
 * However, given that data-urls don't depend on any external data it seemed
 * overkill, therefore I added a special hack that the kio-dataslave is invoked
 * in-process on the client side.
 *
 * Hence, by defining DATAKIOSLAVE you can disable this special hack and compile
 * dataprotocol.* into a standalone kioslave.
