// A wrapper for a stdio FILE object, that mail::mbox finds very useful
//
// The constructor accepts a file descriptor, and a file access mode.
// The original file descriptor is not touched, the object dupes it, and
// attaches the dupe to a FILE object.
//
// The FILE object is cleaned up by the destructor.
