We try to keep an (almost) updated gzipped tar file (textbook.tar.gz or textbook.tgz) of the TextBook content in our server for convenient downloading (remember the terms of our copyright!):
If you are using a PC, the easiest way to unpack the file is to use the latest WinZip versions. Also separate gzip/gunzip and tar programs are available.Mac users may find gzip and tar utilities in ftp://ftp.funet.fi/pub/mac/info-mac/ or any other info Mac site (look for directories about compression). Check the 00cmp-abstracts.txt at the beginning of the list for more info. For example, mac-gzip-10.hqx helps with the unzipping. Look programs with 'tar' in their name, also. Note also that Stuffit program can be enhanced to get it read also gzip files!
