dnl
dnl AC_PROG_JAVADOC tests for an existing javadoc generator. It uses the environment
dnl variable JAVADOC then tests in sequence various common javadoc generator.
dnl
dnl If you want to force a specific compiler:
dnl
dnl - at the configure.in level, set JAVADOC=yourgenerator before calling
dnl AC_PROG_JAVADOC
dnl
dnl - at the configure level, setenv JAVADOC
dnl
dnl You can use the JAVADOC variable in your Makefile.in, with @JAVADOC@.
dnl
dnl Note: This macro depends on the autoconf M4 macros for Java programs.
dnl It is VERY IMPORTANT that you download that whole set, some
dnl macros depend on other. Unfortunately, the autoconf archive does not
dnl support the concept of set of macros, so I had to break it for
dnl 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.
