* This is actually a LogProtoServerOptionsStorage structure
* which holds a LogProtoFileReaderOptions instance and the
* LogReader only stores it.
*
* FileOpenerOptions is fortunately independent of this mess.
*
* LogProtoFileReaderOptions only needs to take care about its "extra"
* fields on top of LogProtoServerOptions, that's why we don't call anything
* from the "inherited" class. This is because that class is
* defaulted/initialized/destroyed by LogReader. This layer just manages
* what we happen to store in addition to LogProtoServerOptions.
*
* You have been warned!

* abandoned it, but it should be done eventually.
