+=item get_district LOCATION METHOD
+
+For the location hash in LOCATION, using lookup method METHOD, fetch
+tax district information. Currently the only available method is
+'wa_sales' (the Washington Department of Revenue sales tax lookup).
+
+Returns a hash reference containing the following fields:
+
+- district
+- tax (percentage)
+- taxname
+- exempt_amount (currently zero)
+- city, county, state, country (from
+
+The intent is that you can assign this to an L<FS::cust_main_county>
+object and insert it if there's not yet a tax rate defined for that
+district.
+
+get_district will die on error.
