## Building
opsu! is distributed as a Maven project.
opsu! is distributed as both a Maven and Gradle project.
### Gradle
Gradle builds are built to the `build` directory.
* To run the project, execute the Gradle task `run`.
* To create a single executable JAR file, execute the Gradle task
`build`. This will compile a jar to `build/libs/opsu-${version}.jar` with
the libraries, resources and natives packed inside the jar.
### Maven
Maven builds are built to the `target` directory.
* To run the project, execute the Maven goal `compile exec:exec`.
* To create a single executable JAR file, execute the Maven goal
`install -Djar`. This will link the LWJGL native libraries using a
