Tucan manager

Tucan Manager is a free and open source and multiplatform software designed for automatic management of downloads and uploads at hosting sites like rapidshare or megaupload. It is released under GPLv2 license. What I really like on tucan is, that it checks all the links first before downloading. If you don't have premium account and you have to wait some time between downloads, tucan will check the time and start downloading files immediately after this period of time expired. For more info check the homepage http://tucaneando.com/index-en.html Deb install file is available from here: http://www.getdeb.net/app/Tucan
