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.ac, is included in the AC_PROG_JAVA macro.
