"""Reliable URL parser.
This parses URLs and provides attributes for the following
components:
<scheme>://<user>:<passwd>@<host>:<port>/<path>?<query>#<fragment>
Missing components are set to None. The only exception is
fragment, which is set to '' if present but empty.
If parsefragment is False, fragment is included in query. If
parsequery is False, query is included in path. If both are
False, both fragment and query are included in path.
See http://www.ietf.org/rfc/rfc2396.txt for more information.
Note that for backward compatibility reasons, bundle URLs do not
take host names. That means 'bundle://../' has a path of '../'.
Examples:
>>> url('http://www.ietf.org/rfc/rfc2396.txt')
<url scheme: 'http', host: 'www.ietf.org', path: 'rfc/rfc2396.txt'>
>>> url('ssh://[::1]:2200//home/joe/repo')
<url scheme: 'ssh', host: '[::1]', port: '2200', path: '/home/joe/repo'>
>>> url('file:///home/joe/repo')
<url scheme: 'file', path: '/home/joe/repo'>
>>> url('bundle:foo')
<url scheme: 'bundle', path: 'foo'>
>>> url('bundle://../foo')
<url scheme: 'bundle', path: '../foo'>
>>> url('c:\\\\foo\\\\bar')
<url path: 'c:\\\\foo\\\\bar'>
Authentication credentials:
>>> url('ssh://joe:xyz@x/repo')
<url scheme: 'ssh', user: 'joe', passwd: 'xyz', host: 'x', path: 'repo'>
>>> url('ssh://joe@x/repo')
<url scheme: 'ssh', user: 'joe', host: 'x', path: 'repo'>
Query strings and fragments:
>>> url('http://host/a?b#c')
<url scheme: 'http', host: 'host', path: 'a', query: 'b', fragment: 'c'>
>>> url('http://host/a?b#c', parsequery=False, parsefragment=False)
<url scheme: 'http', host: 'host', path: 'a?b#c'>
