Subject: sbt 0.5.1

[Mark Harrah]

I'd like to announce sbt 0.5.1. The major new feature in this release
since 0.4.6 is support for publishing and using plugins. The major
polished feature in this release is building and publishing against
multiple Scala versions. Finally, there is a new option for setting
up a scratch project quickly.

Thanks to Nathan for testing 0.5. For those who tried out the
unofficial 0.5 release, the 0.5.1 release contains a few fixes, but
otherwise no major changes.

Somewhat related, Scala X-Ray is now published on scala-tools.org for
easy integration in your build. Thanks to Josh for helping set this
up. There is also a first sbt plugin that creates a self-extracting
jar from your project. You can check this out for the hello-lift
example on the SbtPlugins page[2].

Please note that a couple of new features require an updated loader
(version 0.5 or later). As always, please see the change summary[1]
for details.

Thanks,
Mark
