Abstract:

    This file provides definitions needed internally to provide limited
    support of the win31/win32 registry apis under dos and win30.

    Only REG_SZ data (asciiz string) is supported.

    The data is stored in an ascii file. Each line is in the form:
    
        <Keyname>=<Value>
