Sorry code pasting isn't a good idea for this when you can easily get it from the package it self.
EDIT:
Oh yeah... if you deleted it and you can't get the package directly on your computer, like say you are on a windows machine, 7-zip should be able to extract the contents. If it doesn't like the file extension; change it to .tar.xz
