An alternative script for running sbt. It works with sbt 0.13.0 projects and (in principle) all earlier versions. If you're in an sbt project directory, the system will figure out the required versions of sbt and scala, downloading them if necessary.
Put the (self-contained) sbt script somewhere on your path.
curl -s https://raw.githubusercontent.com/paulp/sbt-extras/master/sbt > ~/bin/sbt && chmod 0755 ~/bin/sbt
sbt -v[erbosely] creating a new project built with the latest scala 2.10.x.

Detected sbt version 0.13.0
Using $HOME/.sbt/0.13.0 as sbt dir, -sbt-dir to override.

about
[info] Setting version to 2.10.3-RC1
[info] This is sbt 0.13.0
[info] The current project is built against Scala 2.10.3-RC1
[info] sbt, sbt plugins, and build definitions are using Scala 2.10.2
Usage: sbt [options]
Note that options which are passed along to sbt begin with -- whereas
options to this runner use a single dash. Any sbt command can be scheduled
to run first by prefixing the command with --, so --warn, --error and so on
are not special.
-h | -help print this message
-v verbose operation (this runner is chattier)
-d, -w, -q aliases for --debug, --warn, --error (q means quiet)
-trace <level> display stack traces with a max of <level> frames (default: -1, traces suppressed)
-no-colors disable ANSI color codes
-sbt-create start sbt even if current directory contains no sbt project
-sbt-dir <path> path to global settings/plugins directory (default: ~/.sbt/<version>)
-sbt-boot <path> path to shared boot directory (default: ~/.sbt/boot in 0.11+)
-ivy <path> path to local Ivy repository (default: ~/.ivy2)
-no-share use all local caches; no sharing
-offline put sbt in offline mode
-jvm-debug <port> Turn on JVM debugging, open at the given port.
-batch Disable interactive mode
-prompt <expr> Set the sbt prompt; in expr, 's' is the State and 'e' is Extracted
# sbt version (default: sbt.version from project/build.properties if present, otherwise 0.13.2)
-sbt-version <version> use the specified version of sbt (default: 0.13.2)
-sbt-jar <path> use the specified jar as the sbt launcher
-sbt-launch-dir <path> directory to hold sbt launchers (default: ~/.sbt/launchers)
-sbt-launch-repo <url> repo url for downloading sbt launcher jar (default: http://typesafe.artifactoryonline.com/typesafe/ivy-releases)
# scala version (default: as chosen by sbt)
-28 use 2.8.2
-29 use 2.9.3
-210 use 2.10.4
-211 use 2.11.0
-scala-home <path> use the scala build at the specified directory
-scala-version <version> use the specified version of scala
-binary-version <version> use the specified scala version when searching for dependencies
# java version (default: java from PATH, currently java version "1.8.0_05")
-java-home <path> alternate JAVA_HOME
# passing options to the jvm - note it does NOT use JAVA_OPTS due to pollution
# The default set is used if JVM_OPTS is unset and no -jvm-opts file is found
<default> -XX:MaxPermSize=384m -Xms512m -Xmx1536m -Xss2m -XX:ReservedCodeCacheSize=256m -XX:+TieredCompilation -XX:+CMSClassUnloadingEnabled -XX:+UseConcMarkSweepGC
JVM_OPTS environment variable holding either the jvm args directly, or
the reference to a file containing jvm args if given path is prepended by '@' (e.g. '@/etc/jvmopts')
Note: "@"-file is overridden by local '.jvmopts' or '-jvm-opts' argument.
-jvm-opts <path> file containing jvm args (if not given, .jvmopts in project root is used if present)
-Dkey=val pass -Dkey=val directly to the jvm
-J-X pass option -X directly to the jvm (-J is stripped)
# passing options to sbt, OR to this runner
SBT_OPTS environment variable holding either the sbt args directly, or
the reference to a file containing sbt args if given path is prepended by '@' (e.g. '@/etc/sbtopts')
Note: "@"-file is overridden by local '.sbtopts' or '-sbt-opts' argument.
-sbt-opts <path> file containing sbt args (if not given, .sbtopts in project root is used if present)
-S-X add -X to sbt's scalacOptions (-S is stripped)
