#
# SYNOPSIS
#
# AC_PROG_JAVA
#
# DESCRIPTION
#
# Here is a summary of the main macros:
#
# AC_PROG_JAVAC: finds a Java compiler.
#
# AC_PROG_JAVA: finds a Java virtual machine.
#
# AC_CHECK_CLASS: finds if we have the given class (beware of
# CLASSPATH!).
#
# AC_CHECK_RQRD_CLASS: finds if we have the given class and stops
# otherwise.
#
# AC_TRY_COMPILE_JAVA: attempt to compile user given source.
#
# AC_TRY_RUN_JAVA: attempt to compile and run user given source.
#
# AC_JAVA_OPTIONS: adds Java configure options.
#
# AC_PROG_JAVA tests an existing Java virtual machine. It uses the
# environment variable JAVA then tests in sequence various common
# Java virtual machines. For political reasons, it starts with the
# free ones. You *must* call [AC_PROG_JAVAC] before.
#
# If you want to force a specific VM:
#
# - at the configure.in level, set JAVA=yourvm before calling
# AC_PROG_JAVA
#
# (but after AC_INIT)
#
# - at the configure level, setenv JAVA
#
# You can use the JAVA variable in your Makefile.in, with @JAVA@.
#
# *Warning*: its success or failure can depend on a proper setting of
# the CLASSPATH env. variable.
#
# TODO: allow to exclude virtual machines (rationale: most Java
# programs cannot run with some VM like kaffe).
#
# 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.
#
# A Web page, with a link to the latest CVS snapshot is at
# <http://www.internatif.org/bortzmeyer/autoconf-Java/>.
#
# This is a sample configure.in Process this file with autoconf to
# produce a configure script.
