* Files for Mac should download properly as .tgz files on a Mac operating system. However, Windows may automatically rename the files to .gz if downloaded on a Windows machine.
** Files for Linux should download properly, without any extension, on a Linux-based system. However, Windows may automatically add .txt to the files, as there is no extension, and Windows associates these as text files. On Windows, you may also need to right-click the link, and select “Save Target As…”, depending upon your Windows web browser.
