Webhook Scripts
===============

These scripts are used to fire and handle webhooks.

* `fire.rb`: Send `POST` request to webhook at given `HOOK_URL` webhook
  with a [SHA256][] [HMAC][] signature in `X-Hub-Signature` header.
  Configuration is handled by the `HOOK_URL` and `HOOK_HMAC_KEY`
  environment variables.
* `deploy.rb`: Verify time in from payload body (to prevent replay
  attacks), execute `git pull`, execute `hugo --minify`, and finally
  update the `htdocs` symlink.
* `post-receive`: Example [Git][] `post-receive` hook.
