+2007-02-04  Bruno Haible  <bruno@clisp.org>
+
+	New module description section 'configure.ac-early'.
+	* gnulib-tool (sed_extract_prog): Recognize configure.ac-early.
+	(func_get_autoconf_early_snippet): New function.
+	(func_import, func_create_testdir): Use it. Remove special cases for
+	modules 'extensions' and 'lock'.
+
 2007-02-04  Bruno Haible  <bruno@clisp.org>
 
 	Make use of gcj-4.3's -fsource and -ftarget option.
