# This Makefile fragment handles Java wrappers and is meant to be included
# by packages that provide a Java build-time and/or run-time environment.
#
# The following variables can be defined in package Makefiles to tune the
# behavior of this file:
#
#	JAVA_CLASSPATH	Classpath that will be prepended on all invocations
#			to this implementation.  Optional.
#
#	JAVA_LD_LIBRARY_PATH
#			Value to prepend to LD_LIBRARY_PATH before running
#			the real command.  Optional; use *only* if necessary.
#
#	JAVA_HOME	Path to the directory holding the Java implementation.
#			Required.
#
#	JAVA_NAME	Base name of the Java implementation.  This will be
#			used as part of wrappers' names.  Required.
#
#	JAVA_UNLIMIT	List of resources to be unlimited at runtime.
#			Can include any of cmdsize, datasize and stacksize.
#			Optional.
#
#	JAVA_WRAPPERS	List of wrappers to be created under ${PREFIX}/bin,
#			pointing to binaries under ${JAVA_HOME}/bin.  The
#			names must match files in the later directory.
#			Required (if empty, the inclusion of this file is
#			useless).
