+* Recursive targets:

+ The user can now define his own recursive targets that recurse
+ in the directories specified in $(SUBDIRS). This can be done by
+ specifying the name of such targets in invocations of the new

built after everything else since they are meant to test what has
been constructed.
+In addition to the built-in recursive targets defined by Automake
+(@code{all}, @code{check}, etc.), the developer can also define his
+own recursive targets. That is done by passing the names of such
+targets as arguments to the m4 macro @code{AM_EXTRA_RECURSIVE_TARGETS}
+in @file{configure.ac}. Automake generates rules to handle the
+recursion for such targets; and the developer can define real actions
+for them by defining corresponding @code{-local} targets.
