Run a web server that displays the path a Nixpkgs pull request will
take through the various release channels.  An instance is available
at the time of writing at <https://tracker.lel.lol/>.


Installation
------------

Build and runtime dependencies:
 - libsystemd
 - OpenSSL

Other build dependencies:
 - Cargo
 - rustc
 - pkg-config

Other runtime dependencies:
 - Git

In most cases, building should be as simple as

	cargo run


Usage
-----

To see usage run:

```sh
./pr-tracker --help
```

The following environment variables are expected:
| Name  | Usage  |
|---|---|
|PR_TRACKER_GITHUB_TOKEN   | A github access token to access the github graphql api.  |
|PR_TRACKER_MAIL_PASSWD   | The password to use for secure email sending.  |

pr-tracker expects the socket(s) for it to listen on to be set up for
it by a service supervisor, using the systemd socket activation
protocol.  It does not support binding its own sockets.  To run
outside of a systemd unit, you can use systemd-socket-activate:

	systemd-socket-activate -l 0.0.0.0:8000 pr-tracker [...]

Further information on available command line arguments can be
obtained with
