-# SYNOPSIS
-#
-# AX_JNI_INCLUDE_DIR
-#
-# DESCRIPTION
-#
-# AX_JNI_INCLUDE_DIR finds include directories needed for compiling
-# programs using the JNI interface.
-#
-# JNI include directories are usually in the Java distribution. This is
-# deduced from the value of $JAVA_HOME, $JAVAC, or the path to "javac", in
-# that order. When this macro completes, a list of directories is left in
-# the variable JNI_INCLUDE_DIRS.
-#
-# Example usage follows:
-#
-# AX_JNI_INCLUDE_DIR
-#
-# for JNI_INCLUDE_DIR in $JNI_INCLUDE_DIRS
-# do
-# CPPFLAGS="$CPPFLAGS -I$JNI_INCLUDE_DIR"
-# done
-#
-# If you want to force a specific compiler:
-#
-# - at the configure.in level, set JAVAC=yourcompiler before calling
-# AX_JNI_INCLUDE_DIR
-#
-# - at the configure level, setenv JAVAC
-#
-# Note: This macro can work with the autoconf M4 macros for Java programs.
-# This particular macro is not part of the original set of macros.
