Minor Description
New version of SBT: 0.10 is out.
Note: it's incompatible with old 0.7.x versions.
https://github.com/harrah/xsbt/wiki/Migrating-from-SBT-0.7.x-to-0.10.x
Why move to 0.10?
-Faster builds (because it is smarter at re-compiling only what it must)
-Easier configuration. For simple projects a single build.sbt file in your root directory is easier to create than project/build/MyProject.scala was.
-No more lib_managed directory, reducing disk usage and avoiding backup and version control hassles.
-update is now much faster and it's invoked automatically by sbt.
-Terser output. (Yet you can ask for more details if something goes wrong.)
