# 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: jdk sun-jdk13 blackdown-jdk13 kaffe
#		sun-jdk14 jdk14 sun-jdk15 scsl-jdk15
#	Default value: (platform-dependent)
#
# Package-settable variables:
#
# USE_JAVA
#	When set to "yes", a build-time dependency on the JDK is added.
#	When set to "run", a run-time dependency on the JRE is added.
#
#	Possible values: yes run
#	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" or "1.5" to
#	require an even more recent implementation.
#
#	Possible values: yes no 1.4 1.5
#	Default value: no
#
# PKG_JVMS_ACCEPTED
#	The list of JVMs that may be used as possible implementations.
#
# Variables set by this file:
#
# PKG_JVM
#	The name of the selected Java implementation.
#
# PKG_JAVA_HOME
#	The directory where the JVM is installed.
