dh-autoreconf provides a debhelper sequence addon named 'autoreconf' and twocommands, 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 allfiles 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 atthe right time.
