The installation requires the PEAR installer, which keeps track of the rest.
git clone git://github.com/till/Services_Scrim.git
cd Services_Scrim
pear package
pear install -f Services_Scrim-0.1.0.tgz
phpunit tests/Services_ScrimTestCase.php
$service = new Services_Scrim;
$service->setEmail('your@email');
$scrim = $service->generate();
echo $scrim;
var_dump($scrim->getUrl(), $scrim->getEmail(), $scrim->isOld());
