OBS source services

Hi folks,

is there any detailed documentation of the OBS source services (i.e. which <param> does exactly what)?

Especially I want to know:

(regarding project is https://build.opensuse.org/package/files?package=fatsort&project=home%3AlOtz1009%3Atesting)

I checkout the latest source from svn via the source service.
When I do this without a versionprefix I receive a simple {name}-{rev}.tar
If I use the versionprefix (which I need for updating the version in the spec) I receive a {name}-{versionprefix}.rev{rev}.tar

Any chance to get rid of that rev?

Not trying to awaken a dead post but I have the same issue. I want to grab my code from svn but my spec file expects just the {name}.tar. I could probably rename things within my spec file but it would be nice if it just polled the name we enter with the filename option then allow us to append additional options with the other parameters.

A good description of all the services and options would be great too.

The wiki seems to be lacking on how to use source services. Unless i just cannot find an updated page.
