+# SYNOPSIS
+#
+#   AX_SPEC_FILE [(rpmspecfile [,subdirpath])]
+#
+# DESCRIPTION
+#
+#   set the specfile - if no argument has been given then check whether
+#   the ac_unique_file looks like a .spec file and use it. This macro
+#   is ac_REQUIRED by many AX_SPEC_ routines.
+#
+#   the AX_SPEC_EXTRACT macro is a helper used by many AX_SPEC_
+#   routines and therefore placed here to be automatically included in
+#   the macro set of (older) aclocal/acinclude.
+#
+#   AX_SPEC_EXTRACT(shellvar [,specvar [,defaultvalue]])
