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.
