Overview
The Launchpad strategy identifies versions of software at launchpad.net by checking the main page for a project.
Launchpad URLs take a variety of formats but all the current formats contain the project name as the first part of the URL path:
https://launchpad.net/example/1.2/1.2.3/+download/example-1.2.3.tar.gz
https://launchpad.net/example/trunk/1.2.3/+download/example-1.2.3.tar.gz
https://code.launchpad.net/example/1.2/1.2.3/+download/example-1.2.3.tar.gz
The default regex identifies the latest version within an HTML element found on the main page for a project:
<div class="version">
Latest version is 1.2.3
</div>
