These DSLs in Scala can be awful. I mean:

    val ivySvn = "ivysvn" % "ivysvn" % "2.1.0" from "http://maven.twttr.com/ivysvn/ivysvn/2.1.0/ivysvn-2.1.0.jar"

Oh, but if you use a different maven convention, just double up the first percent sign:

    val ivySvn = "ivysvn" %% "ivysvn" % "2.1.0" from "http://maven.twttr.com/ivysvn/ivysvn/2.1.0/ivysvn-2.1.0.jar"

Readable, yes; intuitive, no.
