5# SYNOPSIS
6#
7#   AX_PROG_JAVADOC
8#
9# DESCRIPTION
10#
11#   AX_PROG_JAVADOC tests for an existing javadoc generator. It uses the
12#   environment variable JAVADOC then tests in sequence various common
13#   javadoc generator.
14#
15#   If you want to force a specific compiler:
16#
17#   - at the configure.in level, set JAVADOC=yourgenerator before calling
18#   AX_PROG_JAVADOC
19#
20#   - at the configure level, setenv JAVADOC
21#
22#   You can use the JAVADOC variable in your Makefile.in, with @JAVADOC@.
23#
24#   Note: This macro depends on the autoconf M4 macros for Java programs. It
25#   is VERY IMPORTANT that you download that whole set, some macros depend
26#   on other. Unfortunately, the autoconf archive does not support the
27#   concept of set of macros, so I had to break it for submission.
28#
29#   The general documentation of those macros, as well as the sample
30#   configure.in, is included in the AX_PROG_JAVA macro.
