A Domain Specific Language (DSL) is a small language optimized for a specific domain.

For example the dot language of Graphviz allows you to write a textual description of a graph which is then transformed into a picture by one of the graphviz tools (such as dot). A simple graph looks like this:

graph {
    graph [bgcolor="yellow"]
    a [color="red"]
    b [color="blue"]
    a -- b [color="green"]
}

Putting this in a file example.dot and running dot example.dot -T png -o example.png creates an image example.png with red and blue circle connected by a green line on a yellow background.

Create a DSL similar to the dot language.
