 # This make fragment is included by the toplevel make to handle configure
 # and setup. It defines a target called startup that when run will init
-# the build directory, generate configure from configure.in, create aclocal
+# the build directory, generate configure from configure.ac, create aclocal
 # and has rules to run config.status should one of the .in files change.
 
 # Input
-#  BUILD - The build director
+#  BUILDDIR - The build directory
 #  CONVERTED - List of files output by configure $(BUILD) is prepended
 #              The caller must provide depends for these files
 # It would be a fairly good idea to run this after a cvs checkout.
