-# 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.
