sql2data fetches DNS information from an SQL database and dumps then in tinydns-data format into the file 'data'. Additional static DNS data from the text file static_data are copied into 'data'. sql2data optionally executes 'make' upon successful export/dump. Backups can be made to the files old_data and good_data.cdb. Optionally, DNS NOTIFY packets may be sent to the different nameservers referenced for the different zones.
