+# SYNOPSIS
+#
+# AX_CHECK_CLASS
+#
+# DESCRIPTION
+#
+# AX_CHECK_CLASS tests the existence of a given Java class, either in a
+# jar or in a '.class' file.
+#
+# *Warning*: 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.
