When calling the FSPackage tool from the command prompt it will show the output from the compilation in the command prompt window. But when calling the FSPackage tool from another application it is not possible to redirect this console output to that other application, as it seems that it is not written to standard output but in some other way.
Would it be possible to write to standard output so that the FSPackageTool can be integrated into other tools easier?
MSFS 2020 did function like that in the beginning, but also for that sim it seems broken now.
