Detailed Description

Class taking care of dynamic loading.

It contains wrappers to the dlopen() routine. It is designed so that when an object of this class goes out of scope all the libraries loaded by it are unloaded. In this manner, loaded libraries are automatically unloaded at the end of execution. Libraries are loaded with RTDL_LOCAL option, which means that they are not accessible from outside. Still, if they contain self-registering classes, they will register themselves to the ActionRegister object.
