+# Note that this file must exist, even though it is empty (there is no
+# "base" directory for the common framework).  autogen.pl and
+# opal_mca.m4 assume that every framework has a top-level Makefile.am.
+# We *could* adjust the framework glue code to exclude "common" from
+# this requirement, but it's just a lot easier to have an empty
+# Makefile.am here.
