Actually, I'm thinking it may be nicer if the artifact name contained the scala version used to compile it, just like in the past. i.e.,

<groupId>com.typesafe.sbt</groupId>
<artifactId>sbt-interface_${scala.version}</artifactId>
<version>${sbt.version}</version>

where, for instance, ${scala.version} could be 2.10.3-SNAPSHOT and ${sbt.version} could be 0.13.0-SNAPSHOT

This is preferable because we can easily tell if we are using the wrong binaries by just looking at the name.

@jsuereth, is there any (technical) reason we can't do it this way?
