#
# This module finds if Java is installed and determines where the
# include files and libraries are. This code sets the following
# variables:
#
#  JAVA_RUNTIME        = the full path to the Java runtime
#  JAVA_COMPILE        = the full path to the Java compiler
#  JAVA_ARCHIVE        = the full path to the Java archiver
