Mozart
Developers tool for WordPress plugins
...Gone are the days when plugins could load conflicting versions of the same package, resulting in hard-to-reproduce bugs. This package requires PHP 7.3 or higher in order to run the tool. You can use the resulting files as a bundle, requiring any PHP version you like, even PHP 5.2. Mozart brings its own dependencies to the table and that potentially introduces its own problems (yes, I realise how meta that is, for a package like this). That's why installing Mozart in isolation, either through the Docker container, the available PHAR file or installing Mozart as a global dependency with Composer is prefered.
