Add "dump configuration" mode of operation which generates a .BAT file capabile of re-creating the dumped service

For background, please see https://lists.apache.org/list.html?users@tomcat.apache.org:lte=1M:%2F%2FES%2F%2Fexample

Users upgrading their Apache Tomcat or Java versions are finding that they have to manually copy all of their configuration to a temporary location, delete their Windows Service, create a replacement Windows Service, and re-configure everything.

It should be possible to add another mode of operation where procrun dumps all the information stored in the Windows Registry for the Windows Service our to a .BAT file which contains all of the configuration. The file could then be edited and run to re-create the service with minimal effort, and fewer opportunities for mistakes.
