+/*! \brief Manages dynamic libraries.
+ *
+ * The Dynamic Library Manager provides a platform independent way to work with
+ * dynamic library. It load a specific dynamic library, and can returns specific
+ * symbol exported by the dynamic library.
+ *
+ * If an error occurs, a DynamicLibraryManagerException is thrown.
+ *
+ * \internal Implementation of the OS independent methods is in 
+ * DynamicLibraryManager.cpp.
+ *
+ * \internal Porting to a new platform:
+ * - Adds platform detection in config/SelectDllLoader.h. Should define a specific
+ *   macro for that platform of the form: CPPUNIT_HAVE_XYZ_DLL_LOADER, where
+ *   XYZ is the platform.
+ * - Makes a copy of UnixDynamicLibraryManager.cpp and named it after the platform.
+ * - Updated the 'guard' in your file (CPPUNIT_HAVE_XYZ_DLL_LOADER) so that it is
+ *   only processed if the matching platform has been detected.
+ * - Change the implementation of methods doLoadLibrary(), doReleaseLibrary(), 
+ *   doFindSymbol() in your copy. Those methods usually maps directly to OS calls.
+ * - Adds the file to the project.
