It's an application test I've done for a company. The goal is to implement the
specification from subject.pdf in any object oriented programming language.

open subject.pdf

cd mower-o-tron
php App.php test_file

That's it.

Add your new PHP class files in app/Mower/<dir_name>/<ClassFile>.php
If you haven't already, go and install Composer right meow.
To update the class autoloader, from mower-o-tron directory run the command:

composer dump-autoload -o       

Why would you need to to that ? It will generate a file like its' name imply will
'auto-load' (see App.php line 8) the new class files you created so that you don't
have to use require_once() in App.php every single time your extend this program.
You're now free to code as you like with 'namespace' and 'use' for your shiny classes.

Have fun.

Open up a console and enter composer to see and extend list of options.
To see a specifict command enter composer <specific_command> --help
