+ MODULE: service.h
+
+ Comments:  The use of this header file and the accompanying service.c
+ file simplifies the process of writting a service.  You as a developer
+ simply need to follow the TODO's outlined in this header file, and
+ implement the ServiceStart() and ServiceStop() functions.
+
+ There is no need to modify the code in service.c.  Just add service.c
+ to your project and link with the following libraries...
+
+ libcmt.lib kernel32.lib advapi.lib shell32.lib
+
+ This code also supports unicode.  Be sure to compile both service.c and
+ and code #include "service.h" with the same Unicode setting.
+
+ Upon completion, your code will have the following command line interface
+
+ <service exe> -?                to display this list
+ <service exe> -install          to install the service
+ <service exe> -remove           to remove the service
+ <service exe> -debug <params>   to run as a console app for debugging
+
+ Note: This code also implements Ctrl+C and Ctrl+Break handlers
+       when using the debug option.  These console events cause
+       your ServiceStop routine to be called
+
+       Also, this code only handles the OWN_SERVICE service type
+       running in the LOCAL_SYSTEM security context.
+
+       To control your service ( start, stop, etc ) you may use the
+       Services control panel applet or the NET.EXE program.
+
+       To aid in writing/debugging service, the
+       SDK contains a utility (MSTOOLS\BIN\SC.EXE) that
+       can be used to control, configure, or obtain service status.
+       SC displays complete status for any service/driver
+       in the service database, and allows any of the configuration
+       parameters to be easily changed at the command line.
+       For more information on SC.EXE, type SC at the command line.
