The Windows installer of the JobScheduler Universal Agent creates an instance script .\bin\jobscheduler_agent_<port>.cmd according to the data which are specified during the installation.
However, the installer doesn't provide an example of an instance script that could later on be applied by users who want to add instances starting from an existing Agent installation.
The tarball for manual installation of the JobScheduler Universal Agent includes such a script.
Desired Behavior
Universal Agent Windows installer should create the file .\bin\jobscheduler_agent_instance.cmd-example as an example of an instance script.
Workaround
The file .\bin\jobscheduler_agent_<port>.cmd can be used as an example.
