Ideas: 1. Use [pythontex](https://www.ctan.org/pkg/pythontex) and the remote PlantUML server using [Python's plantuml](https://pypi.python.org/pypi/plantuml). 2. Use [pythontex](https://www.ctan.org/pkg/pythontex) and its `bash` functionality to locally execute PlantUML. - This would also solve #2 - Issue: Unclear how I get latex counters into the bash code: https://tex.stackexchange.com/q/419102/9075 3. Build on [checklistings](https://www.ctan.org/pkg/checklistings), which generates a `checklistings.sh` file for the compiler. Drawback: Users have to call an external tool. 4. Use [bashful](https://ctan.org/pkg/bashful) to execute bash scripts. 5. Use [hvextern](https://ctan.org/pkg/hvextern) The package [download](https://ctan.org/pkg/download) can download files, but this does not help much here as we can also download plantuml within a bash script.
