===============================

This service can be enabled to run during buildtime, when it will edit the
Dockerfile to expand the PREFIXEDLABEL instruction.

Example:

```
FROM opensuse/tumbleweed
# labelprefix=org.opensuse.nano
PREFIXEDLABEL org.opencontainers.image.title="Example container"
PREFIXEDLABEL org.opencontainers.image.description="This contains nano"
```

expands to

```
FROM opensuse/tumbleweed
LABEL org.opensuse.nano.title="Example container"
LABEL org.opencontainers.image.title="Example container"
LABEL org.opensuse.nano.description="This contains nano"
LABEL org.opencontainers.image.description="This contains nano"
```
