-dnl Note: This is part of the set of autoconf M4 macros for Java
-dnl programs. It is VERY IMPORTANT that you download the whole set,
-dnl some macros depend on other. Unfortunately, the autoconf archive
-dnl does not support the concept of set of macros, so I had to break it
-dnl for submission. The general documentation, as well as the sample
-dnl configure.in, is included in the AC_PROG_JAVA macro.
