ClientCookie is a Python module for handling HTTP cookies on the
client side, useful for accessing web sites that require cookies
to be set and then returned later.  It also provides some other
(optional) useful stuff: HTTP-EQUIV and Refresh handling, automatic
adding of the Referer [sic] header and lazily-seek()able responses.
These extras are implemented using an extension that makes it easier to
add new functionality to urllib2.  It has developed from a port of
Gisle Aas' Perl module HTTP::Cookies, from the libwww-perl library.
