cash - Yet another hilarious toy shell project

Introduction

cash, short for Can't Afford a SHell, is a toy shell project aimed at hilarity and amusement. (That's exactly what a TOY is meant to do.)

It's written by me (yes, me, but who am I?) during an annoying afternoon, as I am just told that this assignment has to be submitted tonight.

Anyway, should you accept it or not, may you have a great time and enjoy this toy.
