# This Makefile fragment handles Java dependencies and make variables,
# and is meant to be included by packages that require Java either at
# build-time or at run-time.
#
# User-settable variables:
#
# PKG_JVM_DEFAULT
#	The JVM that should be used if nothing particular is specified.
#
#	Possible values: kaffe openjdk7 openjdk7-bin
#		sun-jdk6 jdk15 jdk16
#	Default value: (platform-dependent)
#
# Package-settable variables:
#
# USE_JAVA
#	When set to "yes", a build-time dependency on the JDK and
#	                   a run-time dependency on the JRE are added.
#	When set to "run", a run-time dependency on the JRE is added.
#	When set to "build", a build-time dependency on the JRE is added.
#
#	Possible values: yes run build
#	Default value: yes
#
# USE_JAVA2
#	When the package needs a Java 2 implementation, this variable
#	should be set to "yes". It can also be set to "1.4", "1.5",
#	or "6" require an even more recent implementation.
#
#	Possible values: yes no 1.4 1.5 6
#	Default value: no
#
# PKG_JVMS_ACCEPTED
#	The list of JVMs that may be used as possible implementations.
#
# Variables set by this file:
#
# JAVA_BINPREFIX
#	The prefix for the Java binaries. The path to the real binaries
#	is constructed by appending -${program} to it.
#
#	Examples:
#	* ${JAVA_BINPREFIX}-java is the path to the Java interpreter.
#	* ${JAVA_BINPREFIX}-javac is the path to the Java compiler.
#
# PKG_JVM
#	The name of the selected Java implementation.
#
# PKG_JAVA_HOME
#	The directory where the JVM is installed.
