The current official version of the yarrg screenscraper can browsed here: http://www.chiark.greenend.org.uk/~ijackson/ypp-sc-tools/master/ . See particularly the YARRG README.
To install the client, install the "git" version control system and the other dependencies listed in the "Installation requirements" section of the README and then run:
git-clone http://www.chiark.greenend.org.uk/~ijackson/ypp-sc-tools/master/.git ypp-sc-tools cd ypp-sc-tools cd yarrg makethis will download the code into the directory
ypp-sc-tools, and build the software. (If your Linux is very up to date you may find that it complains that it doesn't know the command git-clone. In that case, use git clone, with a space, instead.)
When new versions of the upload client are released, you can:
cd .../ypp-sc-tools git-pull cd yarrg maketo fetch the new version. (Again, you may need git pull instead of git-pull.)
The yarrg scraper would be almost impossible to port to Windows. In any case it is obsolete.
