dnl @synopsis AC_PROG_JAVADOC

dnl

dnl AC_PROG_JAVADOC tests for an existing javadoc generator. It uses

dnl the environment variable JAVADOC then tests in sequence various

dnl common javadoc generator.

dnl

dnl If you want to force a specific compiler:

dnl

dnl - at the configure.in level, set JAVADOC=yourgenerator before

dnl calling AC_PROG_JAVADOC

dnl

dnl - at the configure level, setenv JAVADOC

dnl

dnl You can use the JAVADOC variable in your Makefile.in, with

dnl @JAVADOC@.

dnl

dnl Note: This macro depends on the autoconf M4 macros for Java

dnl programs. It is VERY IMPORTANT that you download that whole set,

dnl some macros depend on other. Unfortunately, the autoconf archive

dnl does not support the concept of set of macros, so I had to break it

dnl for submission.

dnl

dnl The general documentation of those macros, as well as the sample

dnl configure.in, is included in the AC_PROG_JAVA macro.
