#
# 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.  java-vm.mk will:
#
#	* set PKG_JVM and PKG_JAVA_HOME to the name of the JVM used and
#	  to the directory in which the JVM is installed, respectively;
#
#	* add a full dependency on the JRE and possibly a build dependency
#	  on the JDK.
#
# There are four variables used to tweak the JVM selection:
#
# USE_JAVA is used to note whether a build-time dependency on the JDK is
#	added (the default).  If USE_JAVA is set to "run", then we _don't_
#	add the dependency on the JDK.  The default value is "yes".
#
# USE_JAVA2 is used to note that the package requires a Java2 implementation.
#	It's undefined by default, but may be set to "yes".
#
# PKG_JVM_DEFAULT is a user-settable variable whose value is the default
#	JVM to use.
#
# PKG_JVMS_ACCEPTED is a package-settable list of JVMs that may be used as
#	possible dependencies for the package.
