How to run python macros in LibreOffice?

When I go to Tools -> Macros -> Organize Macros -> Python I get this dialog: It is not possible to create new Python macros. Apparently LibreOffice has no Python editor so I have to write the macros elsewhere and then just execute them. But I do not know where to put the Python scripts. I tried a system-wide search for files with "HeloWorld" in their name and I got no results. I tried to put a test.py file into: ``` /home/martin/.config/libreoffice/4/user/Scripts ``` and reload the application, but the test macro is not shown. I tried to find the appropriate setting in Tools -> Options -> Path but there is no "path to macros": How can I run Python macros from LibreOffice? This question is a part of my quest to learn Python and to learn LibreOffice macros, so any link to a general tutorial is welcomed. The tutorials on LibreOffice Python macros seem to be especially hard to find. I am using LibreOffice Version: 4.1.3.2
