Halcyon examples
Halcyon is a system for installing Haskell apps and development tools, including GHC and Cabal.
These examples are intended to demonstrate advanced Halcyon features.
Each example app can be installed in one command on most recent Linux distributions, including CentOS 7, Debian 7, Fedora 20, and Ubuntu 14.04.
Additionally, each example app can be deployed in one click to DigitalOcean or Heroku.
