1. About
 
 DADVAPI is HX's emulation of ADVAPI32.DLL. The registry API is 
 implemented to some degree, the rest are just dummies.
 
 The content of the registry is stored in private profile files. This is
 a simple approach and it also makes it easy to add new entries, because
 this format is supported when a registry branch is to be exported.

 The profile files must be located in the same directory where DADVAPI.DLL
 is stored, and the filenames are:

 root key             filename
 --------------------------------------------
 HKEY_CLASSES_ROOT    "Classes"
 HKEY_LOCAL_MACHINE   "System"
 HKEY_CURRENT_USER    %USERNAME% (or "DOS")
