#-------------------------------------------------------------------------------
# Variables that each port can define:
#
# USE_JAVA			Should be defined to the remaining variables to have any
#					effect
#
# JAVA_VERSION		List of space-separated suitable java versions for the
#					port. An optional "+" allows you to specify a range of
#					versions. (allowed values: 1.3[+] 1.4[+] 1.5[+] 1.6[+]
#					1.7[+])
#
# JAVA_OS			List of space-separated suitable JDK port operating systems
#					for the port. (allowed values: native linux)
#
# JAVA_VENDOR		List of space-separated suitable JDK port vendors for the
#					port. (allowed values: freebsd bsdjava sun blackdown)
#
# JAVA_BUILD		When set, it means that the selected JDK port should be
#					added to build dependencies for the port.
#
# JAVA_RUN			This variable works exactly the same as JAVA_BUILD but
#					regarding run dependencies.
#
# USE_JIKES			Whether the port should or should not use jikes(1) to build.
#					See Stage 6 header for further detail.
#
# USE_ANT			Should be defined when the port uses Apache Ant. Ant is thus
#					considered to be the sub-make command. When no 'do-build'
#					target is defined by the port, a default one will be set
#					that simply runs Ant according to MAKE_ENV, MAKE_ARGS and
#					ALL_TARGET. Read the documentation in bsd.port.mk for more
#					information.
#
#-------------------------------------------------------------------------------
# Variables defined for the port:
#
# JAVA_PORT			The name of the JDK port. (e.g. 'java/jdk14')
#
# JAVA_PORT_VERSION	The version of the JDK port. (e.g. '1.4')
#
# JAVA_PORT_OS		The operating system used by the JDK port. (e.g. 'linux')
#
# JAVA_PORT_VENDOR	The vendor of the JDK port. (e.g. 'sun')
#
# JAVA_PORT_OS_DESCRIPTION		Description of the operating system used by the
#								JDK port. (e.g. 'Linux')
#
# JAVA_PORT_VENDOR_DESCRIPTION	Description of the vendor of the JDK port.
#								(e.g. 'FreeBSD Foundation')
#
# JAVA_HOME			Path to the installation directory of the JDK. (e.g.
#					'/usr/local/jdk1.3.1')
#
# JAVAC				Path to the Java compiler to use. (e.g.
#					'/usr/local/jdk1.5.0/bin/javac' or '/usr/local/bin/jikes')
#
# JAR				Path to the JAR tool to use. (e.g.
#					'/usr/local/jdk1.5.0/bin/jar' or '/usr/local/bin/fastjar')
#
# APPLETVIEWER		Path to the appletviewer utility. (e.g.
#					'/usr/local/linux-jdk1.3.1/bin/appletviewer')
#
# JAVA				Path to the java executable. Use this for executing Java
#					programs. (e.g. '/usr/local/jdk1.3.1/bin/java')
#
# JAVADOC			Path to the javadoc utility program.
#
# JAVAH				Path to the javah program.
#
# JAVAP				Path to the javap program.
#
# JAVA_KEYTOOL		Path to the keytool utility program.
#
# JAVA_N2A			Path to the native2ascii tool.
#
# JAVA_POLICYTOOL	Path to the policytool program.
#
# JAVA_SERIALVER	Path to the serialver utility program.
#
# RMIC				Path to the RMI stub/skeleton generator, rmic.
#
# RMIREGISTRY		Path to the RMI registry program, rmiregistry.
#
# RMID				Path to the RMI daemon program.
#
# JAVA_CLASSES		Path to the archive that contains the JDK class files. On
#					most JDKs, this is ${JAVA_HOME}/jre/lib/rt.jar.
#
# JAVASHAREDIR		The base directory for all shared Java resources.
#
# JAVAJARDIR		The directory where a port should install JAR files.
#
# JAVALIBDIR		The directory where JAR files installed by other ports
#					are located.
#
# HAVE_JIKES		Defined and set to "yes" whenever the port will effectively
#					use Jikes. See stage 6 header for further detail.
