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 - this module is simpler.
