"""Creates a simple script to run a java "binary".

jar. This includes correctly setting the classpath and the main class.

# The java command must be executed in the current directory because there may
# be user-supplied paths in the args. The script receives the classpath relative
# to the directory that the script is written in and then, when run, must
