WordPress plugins like objects

I’ve finished porting the wp-utils package to PHP 5.2 and added the tad_Plugin class while at it.
I’ve not done much more than refactoring previously posted and shared functions (check if a plugin is installed, generate a plugin activation link and generate a plugin installation link) in a class to allow for a more object-oriented approach to it.

$helloDolly = new tad_Plugin('Hello Dolly', 'hello-dolly.php', 'hello-dolly'); if ($helloDolly->isNotInstalled()){ $helloDolly->theInstallationLink(); } else if ($helloDolly->isInstalled()){ $helloDolly->theActivationLink(); } 

I appreciate your input
