GitHub - geoffleyland/heroku-buildpack-openresty: Can I build openresty and luarocks from source?

heroku-openresty-buildpack - Get openresty (and Lua) running on Heroku

Most of the brains in this buildpack are shamelessly copied from Leafo's version, but it has some differences:

This buildpack uses openresty directly, rather than a buildpack that installs lua, and then using a template for your project
This builds Openresty and LuaRocks from source, so in some sense it's easier to update when there are new releases

Usage of the buildpack itself is pretty straighforward:

heroku buildpack:set https://github.com/geoffleyland/heroku-buildpack-openresty

Actually getting things to work takes a little longer - it's easier to use this project template.

It'd be nice to build LuaJIT from source (2.1 head?) too, rather than use the one in OpenResty
It'd be nice to version the things left in the cache so that old versions can be deleted when they're out of date
