name:                context-free-art
version:             0.2.0.3
synopsis:            Generate art from context-free grammars
description:
    .
    Create art via context free grammar production rules.
    .
    == Context free grammar primer
    .
    Context free grammars consist of a set of terminal symbols, a set of
    non-terminal symbols, and production rules that map non-terminals to
    other symbols.
    .
    With a context-free grammar, we can generate strings of terminals that
    conform to the specified language.
    .
    Our language will describe graphics.
    .
    == Example
    .
    > import Art.ContextFree
    > import Data.List.NonEmpty
    >
    > -- Let's define a Production rule
    > a = Circle 1
    >
    > -- This will produce an IO Svg from the blaze-svg package
    > -- to turn it into a string we can use one of the `blaze-svg` renderers
    > graphic1 = interpret $ Circle 1
    >
    > -- let's create a non-terminal, 'a', which renders a terminal, 'Circle 1'
    > -- and has an 85% chance of rendering another circle, placed to its right
    > a = NonTerminal $ (100, Circle 1) :| [(85, b)]
    > b = Mod [Move (2, 0)] a
