Pinto::Role::UserAgent - Something that makes network requests
=head1 VERSION
version 0.14
=head1 METHODS
=head2 mirror(RESOURCE => PATH)
Mirrors the resource located at C<from> to the file located at PATH, if the
RESOURCE is newer than the file at PATH.  If the intervening directories do
not exist, they will be created for you. Returns a true value if the file has
changed, returns false if it has not changed.  Throws an exception if anything
goes wrong.
The RESOURCE can be either a L<URI> or L<Path::Class::File> object, or a
string that represents either of those.  The PATH can be a
L<Path::Class::File> object or a string that represents one.
=head2 mirror_temporary(RESOURCE)
Mirrors RESOURCE to a file in a temporary directory.  The file will have the
same basename as the RESOURCE.  Returns a L<Path::Class::File> that points to
the new file.  Throws and exception if anything goes wrong.  Note the
temporary directory and all its contents will be deleted when the process
terminates.
