-Brainfuck
----------
-Urban Müller created brainfuck in 1993 with the intention of designing a language which could be implemented with the smallest possible compiler.
-
-### Commands
-The eight language commands, each consisting of a single character:
-
-| Character | Meaning                                                                                                                                                                           |

-|     <     | decrement the data pointer (to point to the next cell to the left).                                                                                                               |
-|     +     | increment (increase by one) the byte at the data pointer.                                                                                                                         |

-|     ,     | accept one byte of input, storing its value in the byte at the data pointer.                                                                                                      |
-|     [     | if the byte at the data pointer is zero, then instead of moving the instruction pointer forward to the next command, jump it forward to the command after the matching ] command*.|
-|     ]     | if the byte at the data pointer is nonzero, then instead of moving the instruction pointer forward to the next command, jump it back to the command after the matching [ command*.|
