/********************************************************************
/* This is an overview of the opielibs2 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
