Original Description:
This is a simulation of the old times of computers where you inputed every command.
This one simulates a computer taking in C input.
Type "functions();" (no quotes) for the functions available.
This one has a easter egg - good luck finding it!
When you enter commands, press "Execute stdin" to run that command.
The output of commands are found above "Input to System" and below "Output of System". The input box is the box where "welcomeMessage();" is.
EDIT: Added quick sanity check for unknown commands.
EASTER EGG HINT: the function is bsod_now_cuz_im_bore*(); *=4th letter of alphabet
