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