#-------------------------------------------------------------------------------
# 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: 1.6[+] 1.7[+] 1.8[+])
#
# 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: openjdk oracle sun)
#
# JAVA_BUILD        When set, it means that the selected JDK port should be
#                   added to build dependencies for the port.
#
# JAVA_EXTRACT      This variable works exactly the same as JAVA_BUILD but
#                   regarding extract dependencies.
#
# JAVA_RUN          This variable works exactly the same as JAVA_BUILD but
#                   regarding run dependencies.
#
# 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/openjdk6')
#
# JAVA_PORT_VERSION The version of the JDK port. (e.g. '1.6')
#
# 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. 'OpenJDK BSD Porting Team')
#
# JAVA_HOME         Path to the installation directory of the JDK. (e.g.
#                   '/usr/local/openjdk6')
#
# JAVAC             Path to the Java compiler to use. (e.g.
#                   '/usr/local/openjdk6/bin/javac' or '/usr/local/bin/javac')
#
# JAR               Path to the JAR tool to use. (e.g.
#                   '/usr/local/openjdk6/bin/jar' or '/usr/local/bin/fastjar')
#
# APPLETVIEWER      Path to the appletviewer utility. (e.g.
#                   '/usr/local/linux-jdk1.7.0/bin/appletviewer')
#
# JAVA              Path to the java executable. Use this for executing Java
#                   programs. (e.g. '/usr/local/openjdk6/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.

# Stage 1: Define constants
# Stage 2: Determine which JDK ports are installed and which JDK ports are

# Stage 3: Decide the exact JDK to use (or install)
# Stage 4: Add any dependencies if necessary
# Stage 5: Define all settings for the port to use
