|

199 | =head1 DESCRIPTION
|
---|
200 |
|
---|
201 | This module is provided for backwards compatibility with modules that
|
---|
202 | depend on the interface provided by the C<URI::URL> class that used to
|
---|
203 | be distributed with the libwww-perl library.
|
---|
204 |
|
---|
205 | The following differences exist compared to the C<URI> class interface:
|
---|
206 |
|
---|
207 | =over 3
|
---|
208 |
|
---|
209 | =item *
|
---|
210 |
|
---|
211 | The URI::URL module exports the url() function as an alternate
|
---|
212 | constructor interface.
|
---|
213 |
|
---|
214 | =item *
|
---|
215 |
|
---|
216 | The constructor takes an optional $base argument. The C<URI::URL>
|
---|
217 | class is a subclass of C<URI::WithBase>.
|
---|
218 |
|
---|
219 | =item *
|
---|
220 |
|
---|
221 | The URI::URL->newlocal class method is the same as URI::file->new_abs.
