# How it works

One service shows the interface. A thin command line client asks it to open the hive.

## The pieces

![Processes and crates](https://kawaro.sbarah.com/diagrams/overview.en.light.svg)

- `kawarod` holds the hive, the queue, the tray and the engines.
- FFmpeg, LibreOffice and Ghostscript run as separate processes, killed with their whole tree on cancel.
- The original file is never changed: the result is written to a temporary file and then renamed.
