In some temporary directory, unpack the distribution with tar. On most systems you can type "tar -zxvpf mailman_blahblah.tar.gz" and your system will expand the file into all of the MailMan components. (Don't forget to replace the "blahblah" in the above with the version number and other information from your filename. You can also just type "mailman_" and then hit tab in most shells if you're lazy.) You should now have a subdirectory under your current directory called "mailman" that contains all of the files that we talked about in the installation overview. On systems where that doesn't work, try "gnutar zxvpf mailman_blahblah.tar.gz" If that doesn't work, you will have to manually unzip the file with "gunzip mailman_blahblah.tar.gz" and then untar the file with "tar -xvpf mailman_blahblah.tar". If all else fails, fetch the Windows distribution and unzip it on a Windows machine and then FTP them in "text/ASCII" mode to your server. The files are basically the same except for the line endings.
