# Use javah to build the libdb_java/com_*.h header files.
#
# To run this, you will need a javac and javah in your PATH.
# If possible, install tools with a recent vintage, JDK 1.3 or higher is good.
# Using Sun's JDK rather than some other installation ensures
# that the header files will not be constantly changed.
