+dnl AC_PROG_JAVAC tests an existing Java compiler. It uses the
+dnl environment variable JAVAC then tests in sequence various common
+dnl Java compilers. For political reasons, it starts with the free
+dnl ones.
+dnl
+dnl If you want to force a specific compiler:
+dnl
+dnl - at the configure.in level, set JAVAC=yourcompiler before calling
+dnl AC_PROG_JAVAC
+dnl
+dnl - at the configure level, setenv JAVAC
+dnl
+dnl You can use the JAVAC variable in your Makefile.in, with @JAVAC@.
+dnl
+dnl *Warning*: its success or failure can depend on a proper setting of
+dnl the CLASSPATH env. variable.
+dnl
+dnl TODO: allow to exclude compilers (rationale: most Java programs
+dnl cannot compile with some compilers like guavac).
+dnl
+dnl Note: This is part of the set of autoconf M4 macros for Java
+dnl programs. It is VERY IMPORTANT that you download the 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. The general documentation, as well as the sample
+dnl configure.in, is included in the AC_PROG_JAVA macro.

+dnl Here is a summary of the main macros:
+dnl
+dnl AC_PROG_JAVAC: finds a Java compiler.
+dnl
+dnl AC_PROG_JAVA: finds a Java virtual machine.
+dnl
+dnl AC_CHECK_CLASS: finds if we have the given class (beware of
+dnl CLASSPATH!).
+dnl
+dnl AC_CHECK_RQRD_CLASS: finds if we have the given class and stops
+dnl otherwise.
+dnl
+dnl AC_TRY_COMPILE_JAVA: attempt to compile user given source.
+dnl
+dnl AC_TRY_RUN_JAVA: attempt to compile and run user given source.
+dnl
+dnl AC_JAVA_OPTIONS: adds Java configure options.
+dnl
+dnl AC_PROG_JAVA tests an existing Java virtual machine. It uses the
+dnl environment variable JAVA then tests in sequence various common
+dnl Java virtual machines. For political reasons, it starts with the
+dnl free ones. You *must* call [AC_PROG_JAVAC] before.
+dnl
+dnl If you want to force a specific VM:
+dnl
+dnl - at the configure.in level, set JAVA=yourvm before calling
+dnl AC_PROG_JAVA
+dnl
+dnl   (but after AC_INIT)
+dnl
+dnl - at the configure level, setenv JAVA
+dnl
+dnl You can use the JAVA variable in your Makefile.in, with @JAVA@.
+dnl
+dnl *Warning*: its success or failure can depend on a proper setting of
+dnl the CLASSPATH env. variable.
+dnl
+dnl TODO: allow to exclude virtual machines (rationale: most Java
+dnl programs cannot run with some VM like kaffe).
