// This is the main module for the Registry File System Driver (RFSD).
// RFSD presents the system Registry as file volume mounted on a hard
// drive under Windows 95. It does this by first creating a virtual
// drive, and then installing a file system on that virtual drive. The
// file system maps file i/o calls to the system Registry. Specifically,
// directories are mapped to keys, files to values, and file contents
// to value data.
//
// RFSD is both a file system driver and a layered block device driver.
// As a file system driver, it translates file i/o requests into
// calls to services that access the Registry. As a port driver, it
// simulates the existence of a hard drive, and provides routines to
// handle i/o requests to that drive.
// The driver may be built with either Microsoft Visual C++ 2.0 (or
// later) or Borland C++ 4.02 (or later).
