# rule into a (series of) rake tasks. For example if we're looking at a file
# in subdirectory "subdir" contains the line:
#
# java_library(:name => "example", :srcs => ["foo.java"])
#
# we would generate a rake target of "//subdir:example" which would generate
# a Java JAR at "build/subdir/example.jar".
#
# If crazy fun doesn't know how to handle a particular output type ("java_library"
# in the example above) then it will throw an exception, stopping the build
