+# At that point, we import the two PostGIS files, postgis.sql and
+# spatial_ref_sys.sql. The postgis.sql file contains the geometry
+# functions, while spatial_ref_sys.sql contains a table of SRIDs, and
+# their associated properties. PostGIS requires both.
+#
+# Then, we import the Tiger data using shp2pgsql. The shapefiles
+# should exist, since this task depends on the "data" task, which
+# downloads said shapefiles.

+# Finally, we create the table for the demographic data (obtained from
+# the geographic header records), and populate that table with the output
+# of the sf1blocks2sql script.
