You can extract tarballs (.tar, .tar.gz, .tar.bz2 and so on) using the tar command. tar only archives files - puts several files and/or directories together in a single file - so if compression is needed you have to use gzip or bzip2 to compress the tar file - hence the .tar.gz and .tar.bz2 file extensions.
tar extracts to the current directory by default and you can't extract to the CD, so we'll create a temporary directory in our home directory: mkdir ~/abs-files, then hop into that directory: cd ~/abs-files. Now let's extract the files, starting with the bzipped file: tar xfvj /whatever/the/path/is/abs-guide-2.3.tar.bz2
Some prefer using a hyphen before the options to tar but I recommend you do not since you then have to keep in mind in what order to put them. Here I used xfvj: x for extract, f for file, v for verbous (lists the files and directories as they are extracted), and j for bzip2 compression. You will most probably find a directory with the extracted files.
To extract the .tar.gz simply type tar xfvz /wherever/the/file/is/abs-guide.html.tar.gz (here the z indicates gzip compression).
