2002-04-04  Kasper Peeters  <K.Peeters@damtp.cam.ac.uk>	* Fix related to stringstream (Evan Jones) and some minor cleanups	and removal of old email addresses.2002-04-02  Kasper Peeters  <K.Peeters@damtp.cam.ac.uk>	* Several fixes by Evan Jones:	1. liburl does not compile with a standards compliant	compiler. I had to include <stdexcept> and use string::erase()	instead of string::clear().		2. Calling .get_url() on a relative URL created from a base URL	without a scheme would cause an infinite loop.		3. Calling .get_url() on a relative URL created from a relative	URL did not have all the information required.
