liburi-perl 1.35.dfsg.1-1 (lpia binary) in ubuntu jaunty

 From the README:
 .
 This package contains the URI.pm module with friends. The module
 implements the URI class. Objects of this class represent Uniform
 Resource Identifier (URI) references as specified in RFC 2396.
 .
 URI objects can be used to access and manipulate the various
 components that make up these strings. There are also methods to
 combine URIs in various ways.
 .
 The URI class replace the URI::URL class that used to be distributed
 with libwww-perl. This package contains an emulation of the old
 URI::URL interface. The emulated URI::URL implement both the old and
 the new interface.
