We switched to Tycho for our build system, and this executable is automatically generated in the build now. It is an alternative launcher to start openLCA in 'console' mode. When you start the normal GUI executable from the command line on Windows, it launches the application and immediately returns to the command prompt. The console executable, keeps the terminal connection open, allowing you to see the system output (stdout/stderr) written by openLCA directly in the console. We do not support this currently, but it could be used to start openLCA in headless mode (without user interface), e.g. to only start it as an IPC server.
