##### http://autoconf-archive.cryp.to/ac_prog_javadoc.html
#
# SYNOPSIS
#
# AC_PROG_JAVADOC
#
# DESCRIPTION
#
# AC_PROG_JAVADOC tests for an existing javadoc generator. It uses
# the environment variable JAVADOC then tests in sequence various
# common javadoc generator.
#
# If you want to force a specific compiler:
#
# - at the configure.in level, set JAVADOC=yourgenerator before
# calling AC_PROG_JAVADOC
#
# - at the configure level, setenv JAVADOC
#
# You can use the JAVADOC variable in your Makefile.in, with
# @JAVADOC@.
#
# Note: This macro depends on the autoconf M4 macros for Java
# programs. It is VERY IMPORTANT that you download that 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 of those macros, as well as the sample
# configure.in, is included in the AC_PROG_JAVA macro.
