SHaft is a simple UNIX shell implementing most common features, such as:
	* Pipelines
	* Redirections
	* Logical operators && and ||
	* Environment and local variables substitution
	* Function declaration
	* Scripting keywords (if elif else, while, for)
	* Command aliases
	* Command subsitution with `` or $()
   and many others (cf. TODO).

It can be run in interactive mode, or given a script file as parameter.

It is a compact codebase (~3000 SLOC) entirely written by myself as a fun
project over a week. It uses a hand written parser and does not depend on any
external library.
