URI::Query provides simple URI query string manipulation, allowing you
to create and manipulate URI query strings from GET and POST requests in
web applications. This is primarily useful for creating links where you
wish to preserve some subset of the parameters to the current request,
and potentially add or replace others. Given a query string this is
doable with regexes, of course, but making sure you get the anchoring
and escaping right is tedious and error-prone - using this module is
much simpler.
