Initial addition.

This file provides a framework to easily create wrappers to run Java
environments (either compilers or virtual machines) installed under
${PREFIX}/java/<implementation>.  These wrappers hide the complexity
of having to modify the path, unlimit resources or to set a correct
CLASSPATH for the program to run.

+# 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_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).
