 6# libjvm.dll.a    - wrapper lib for jvm.dll from Java
 7# findjava.exe    - helper tool to find the current JDK from the registry
 8# WinRegistry.dll - helper lib to provide registry access to rJava before
 9#                   rJava.dll is loaded, because at that point path to
10#                   jvm.dll must be known. We don't hard-code the JVM path,
11#                   because updates of JRE/JDK can re-locate it.
