-Dies ist ein Testballon für opielibs1.2 - Codename: Cornucopia
----------------------------------------------------------------
+/********************************************************************
+/*     This is an overview of the opielibs 1.2 project
+/********************************************************************/
+
+  Origin: opielibs is about creating classes to
+          * optimize Qt classes for the embedded environment
+          * provide sophisticated abstractions for developers
+          * provide complete documentation and working examples
+          * provide end users with a common look and feel
+          * reduce memory footprint through sharing code
+          * reduce possible bugs through reusing tested code
+
