Hi Byron. Conscript uses the sbt launcher, and so like sbt itself it
uses a copy of Scala (scala-lib and scala-compiler jars) that is managed
by ivy. As far as I know, the same is true of the copy of sbt that is
distributed with the Typesafe Stack; it would be independent of anything
in a Scala home directory.
The good thing about this is it allows sbt, conscript, and anything else
using the sbt launcher to work with any version of Scala--not just
whichever you may have in a directory. So while the current version of
conscript itself uses Scala 2.9.1, some other application managed by
conscript could be using Scala 2.8.2.
