      5 dnl *Warning*: its success or failure can depend on a proper setting of the
      6 dnl CLASSPATH env. variable.
      7 dnl
      8 dnl Note: This is part of the set of autoconf M4 macros for Java programs.
      9 dnl It is VERY IMPORTANT that you download the whole set, some
     10 dnl macros depend on other. Unfortunately, the autoconf archive does not
     11 dnl support the concept of set of macros, so I had to break it for
     12 dnl submission.
     13 dnl The general documentation, as well as the sample configure.in, is
     14 dnl included in the AC_PROG_JAVA macro.
