# Invoke javap with latest Scala 2.9.1 and Akka 2.0 jars
# Does not use SBT or scala scripts, so this actually works on all platforms that have bash, including Cygwin.
# Invoke javap as usual with all options except classpath:
# javap scala.None
# You can add to the classpath with -cp, if that option is provided first:
# javap -cp org.apache.httpcomponents/httpclient/jars/ scala.None
# The additions to the classpath are assumed to exist in the ~.ivy2/cache and must end with /jars/
# The latest jar in that directory will be used
