cryp.to ac-archive's Java Support (released)

Internal use ONLY.

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