+%description
+dh-autoreconf provides a debhelper sequence addon named 'autoreconf' and two
+commands, dh_autoreconf and dh_autoreconf_clean.
+ * The dh_autoreconf command creates a list of the files and their checksums,
+   calls autoreconf and then creates a second list for the new files.
+ * The dh_autoreconf_clean command compares these two lists and removes all
+   files which have been added or changed (files may be excluded if needed).
+For CDBS users, a rule is provided to call the dh-autoreconf programs at the
+right time.
