+mksyscall_windows generates windows system call bodies
+
+It parses all files specified on command line containing function
+prototypes (like syscall_windows.go) and prints system call bodies
+to standard output.
+
+The prototypes are marked by lines beginning with "//sys" and read
+like func declarations if //sys is replaced by func, but:
+
+* The parameter lists must give a name for each argument. This
+  includes return parameters.
+
+* The parameter lists must give a type for each argument:
+  the (x, y, z int) shorthand is not allowed.
+
+* If the return parameter is an error number, it must be named err.
+
+* If go func name needs to be different from it's winapi dll name,
+  the winapi name could be specified at the end, after "=" sign, like
+  //sys LoadLibrary(libname string) (handle uint32, err error) = LoadLibraryA
+
+* Each function that returns err needs to supply a condition, that
+  return value of winapi will be tested against to detect failure.
+  This would set err to windows "last-error", otherwise it will be nil.
+  The value can be provided at end of //sys declaration, like
+  //sys LoadLibrary(libname string) (handle uint32, err error) [failretval==-1] = LoadLibraryA
+  and is [failretval==0] by default.
+
+Usage:
+	mksyscall_windows [flags] [path ...]
+
+The flags are:
+	-output
+		Specify output file name (outputs to console if blank).
+	-trace
+		Generate print statement after every syscall.
