# This script runs Processing, using the JDK in the Processing
# installation directory if possible.
# If no JDK was installed with Processing then the script tries to use
# the preferred Java version of the machine, i.e. what is executed
# by the "java" console command. This must be a Sun JDK (for details, see
# http://processing.org/reference/environment/platforms.html#java).
# In order to run Processing with an already installed JDK that is *not*
# the preferred Java version of the machine, create a symlink named "java"
# in the Processing installation directory that points to the JDK home
# directory.
# Thanks to Ferdinand Kasper for this build script. [fry]
