This is a simple module map for the freeglut library, most likely to be used for Linux. I've used this in a couple of projects in Ubuntu 14.04.
To use, have something like the following in your application's Package.swift:
import PackageDescription let package = Package( dependencies: [ .Package(url: "https://github.com/BradLarson/CFreeGLUT.git", majorVersion: 1) ] )
or clone this locally and use
swiftc -I ./CFreeGLUT myfile.swift
or the like to pull it in.
Then you just need an
in your Swift code to import the freeglut functions.
