+/** \class DynamicLoader
+ * \brief Portable loading of dynamic libraries or dll's.
+ *
+ * DynamicLoader provides a portable interface to loading dynamic
+ * libraries or dll's into a process.
+ *
+ * Directory currently works with Windows, Apple, HP-UX and Unix (POSIX)
+ * operating systems
+ *
+ * \warning dlopen on *nix system works the following way:
+ * If filename contains a slash ("/"), then it is interpreted as a (relative
+ * or absolute) pathname.  Otherwise, the dynamic linker searches for the
+ * library as follows : see ld.so(8) for further details):
+ * Whereas this distinction does not exist on Win32. Therefore ideally you
+ * should be doing full path to garantee to have a consistent way of dealing
+ * with dynamic loading of shared library.
+ *
+ * \warning the Cygwin implementation do not use the Win32 HMODULE. Put extra
+ * condition so that we can include the correct declaration (POSIX)
