#
# SYNOPSIS
#
# AC_PROG_JAVAC
#
# DESCRIPTION
#
# AC_PROG_JAVAC tests an existing Java compiler. It uses the
# environment variable JAVAC then tests in sequence various common
# Java compilers. For political reasons, it starts with the free
# ones.
#
# If you want to force a specific compiler:
#
# - at the configure.in level, set JAVAC=yourcompiler before calling
# AC_PROG_JAVAC
#
# - at the configure level, setenv JAVAC
#
# You can use the JAVAC variable in your Makefile.in, with @JAVAC@.
#
# *Warning*: its success or failure can depend on a proper setting of
# the CLASSPATH env. variable.
#
# TODO: allow to exclude compilers (rationale: most Java programs
# cannot compile with some compilers like guavac).
#
# 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.
