37// with a derived class to perform additional or enhanced functions, you MUST
38// define XrdOfsFS to be an instance of your derived class definition. You
39// would then create a shared library linking against libXrdOfs.a and manually
40// include your definition of XrdOfsFS (obviously upcast to XrdOfs). This
41// is how the standard libXrdOfs.so is built.
