#
# 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.
