| 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. |
