I added a code block to show how to retrieve the musl version. I chose to only briefly describe how to get the musl libc’s path from a Python executable, since the implementation is a bit too long to include in a document, but shouldn’t be too difficult to devise from reading the ELF spec (ref provided in the PEP).
Also note that there’s now a thread for the PEP, so it might be a good idea to move further discussions there so we can keep things in one place
