+# SYNOPSIS
+#
+#   AX_CHECK_RQRD_CLASS
+#
+# DESCRIPTION
+#
+#   AX_CHECK_RQRD_CLASS tests the existence of a given Java class, either in
+#   a jar or in a '.class' file and fails if it doesn't exist. Its success
+#   or failure can depend on a proper setting of the CLASSPATH env.
+#   variable.
+#
+#   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.
