+=item export_getsettings SVC_OBJECT SETTINGS_HASHREF DEFAUTS_HASHREF
+
+Adds a hashref of settings to SETTINGSREF specific to this export and
+SVC_OBJECT. The elements can be displayed in the UI on the service view.
+
+DEFAULTSREF is a hashref with the same keys where true values indicate the
+setting is a default (and thus can be displayed in the UI with less emphasis,
+or hidden by default).
+
+=item actions
+
+Adds one or more "action" links to the export's display in
+browse/part_export.cgi. Should return pairs of values. The first is
+the link label; the second is the Mason path to a document to load.
+The document will show in a popup.

+=item get_dids SELECTION
+
+Does several things, which is unfortunate. DID phone numbers are organized
+in a sort-of hierarchy: state, areacode, exchange, number. Or, for some
+vendors: state, region, number. But not always that, either.
+
+SELECTION is one or more field/value pairs specifying parts of the hierarchy
+that have already been selected. C<get_dids> will then return an arrayref of
+the possible values for the next selection level. Note that these are not
+actual DIDs except at the lowest level.
+
+Generally, 'state' alone will return an array of area codes or region names
+in the state.
+
+'state' and 'areacode' together will return an array of either:
+- exchange strings of the form "New York (212-555-XXXX)"
+- ratecenter names of the form "New York, NY"
+
+These strings are sent back to the UI and offered as options so that the user
+can choose the local calling area they like.
+
+'areacode' and 'exchange', or 'state' and 'ratecenter', or 'region' by itself
+will return an array of actual DID numbers.
+
+Passing 'tollfree' with a true value will override the whole hierarchy and
+return an array of tollfree numbers.
+
+C<get_dids> methods should report errors via die().

+# part_export/vitelity.pm for an example.
