I only wish I had spent a little more time looking at existing tools before
writing those kludges.  Turns out that ogr2ogr has some feature-selecting
options that would have made it easier (you can select features both by
geographic region and by an SQL-like query on dbf records).

Rtree's intent is to allow big shapefiles to work out of the box.  If the
user's willing to spend the time and effort to make more efficient map
data, the payoff is bigger.
