WARNING: to get the source version

• be sure to download the faust-2.81.2.tar.gz file to get a complete source folder (in particular, with all the libraries).
• on macOS, binary files are still to notarise, you may have to use the xattr -rd com.apple.quarantine file command to remove the com.apple.quarantine extended attribute. See the xattr [man page].(https://developer.apple.com/documentation/os/reading_unix_manual_pages) for details on how to use that tool. MacOS Monterey is now the minimal version.
