# Project: OGR Python samples
# Purpose: This little script is basically curl or wget, with the added
# benefit of dumping the contents of the url right out to the
# filesystem. This is useful if you want to roll curl-like
# functionality your python script using the ZipURL class.

# New. Little utility tool to add some curl-like functionality to
# get a zip file from a URL and extract it to a given directory.
# Useful for the ZipURL class which can be added to your own Python
# scripts to do the same thing.
