-# Voerbak
-
-Here's the source for voerbak, this project's connect 4 engine. The name comes from an abbreviation for the Dutch word for connect 4: Vier Op Een Rij -> VOER + bak = voerbak
-
-Voerbak uses a 1-dimensional array for storing the playfield, and it's printed after every move. The ordering is left to right, then bottom to top:

-
-Voerbak is used in this project using api/game/voerbak_connector.py
-
-## Building
-
-```sh
-make
-```
-
-## Input
-
-Voerbak takes moves seperated by newlines from stdin. An example game would look like this:
-
-``` sh
-echo "4,3,3,2,1,2,2,7,1,7,1,7,1" | sed "s/,/\n/g" | ./voerbak
-#                                  ^ convert "," to newline
-```
-
-## Output
-
-Voerbak outputs special messages in this format:
-
-```
-e:full
-^ \__/
-|  |
-|  message (without spaces)
-|
-message type
-```
-
-Message reference:
-
-type|name|messages
--|-|-
-d|draw|full = board is full
-e|errors|full = column is full
-m|move|true|false = if it's player 1's move
-w|win|int-int = board indices where 4 was connected
