# installation directory if possible.

# 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.
