This is the module definition for Rawtherapee. It's pretty simple, so there
shouldn't need to be many changes. See https://src.fedoraproject.org/rpms/rawtherapee
for the RPMs.

There are two streams: devel and stable. The `stable` stream tracks upstream
releases closely, after some basic testing. We may also include critical
security fixes, but again in general we follow an upstream-first model.

The `devel` stream is less cautious. We may include release candidates,
nightly builds, or other experimental / in-development builds.
