A Ruby constraint solver

## Installation

    $ gem install solve

## Usage

Create a new graph

    graph = Graph.new

Add an artifact to the graph

    graph.artifacts("nginx", "1.0.0")

Now add another artifact that has a dependency

    graph.artifacts("mysql", "1.2.4").depends("openssl", "~> 1.0.0")

Dependencies can be chained, too

    graph.artifacts("ntp", "1.0.0").depends("build-essential").depends("yum")

And now solve the graph with some demands

    Solve.it!(graph, ['nginx', '>= 0.100.0'])

### Removing an artifact, or dependency from the graph

    graph.artifacts("nginx", "1.0.0").delete

    artifact.dependencies("nginx", "~> 1.0.0").delete
