+dnl
+dnl Test for the presence of a JDK, and (optionally) specific classes.
+dnl
+dnl If "JAVA" is defined in the environment, that will be the only
+dnl java command tested.  Otherwise, a hard-coded list will be used.
+dnl Similarly for "JAVAC".
+dnl
+dnl AX_JAVAC_AND_JAVA does not currenly support testing for a particular
+dnl Java version, testing for only one of "java" and "javac", or
+dnl compiling or running user-provided Java code.
+dnl
+dnl After AX_JAVAC_AND_JAVA runs, the shell variables "success" and
+dnl "ax_javac_and_java" are set to "yes" or "no", and "JAVAC" and
+dnl "JAVA" are set to the appropriate commands.
+dnl
+dnl AX_CHECK_JAVA_CLASS must be run after AX_JAVAC_AND_JAVA.
+dnl It tests for the presence of a class based on a fully-qualified name.
+dnl It sets the shell variable "success" to "yes" or "no".
