- Parse PHP code and show the abstract syntax tree.
- This command is used in the development of PsySH. Given a string of PHP code,
- it pretty-prints the PHP Parser parse tree.
- See https://github.com/nikic/PHP-Parser
- It prolly won't be super useful for most of you, but it's here if you want to play.
