(Unofficial) stack.yaml Configuration for [semantic]

This is an unofficially supported stack.yaml configuration file for GitHub's semantic project.

The plan is to test for valid build configurations against a matrix of LTS snapshots using GitHub Actions as the CI runner. At the time of writing, the latest configuration is stack-lts-15.yaml.

How do I use this?

1. Ensure that the Haskell Tool Stack is installed
2. Clone the semantic repository
3. Navigate to the cloned repository directory
4. Copy the contents of stack-lts-15.yaml into a file named stack.yaml in that directory
5. Run stack build (this can take a long time)

If that doesn't work, for whatever reason, please open an issue!
