Line 1:
This is an implementation of [[Brainf***]] originally written in [[C++]] by [[User:Short Circuit|Mike Mol]] and [[User:Mwn3d|Mike Neurohr]], for Rosetta Code. It is licensed under the same license as Rosetta Code itself.
It may be fed BF instructions either through standard input (i.e. terminal keyboard input), or through a file named as the first command-line argument.
RCBF is intended for educational purposes only; There is no guarantee it won't lock up your computer. (Though Mike M thinks he's got that bug ironed out...) (We'll no it wasn't, but it should be now -- RdB)
