-# SYNOPSIS
-#
-# AX_PROG_JAVADOC
-#
-# DESCRIPTION
-#
-# AX_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
-# AX_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 AX_PROG_JAVA macro.
