2.5 Extract the Daisy download
Extract the Daisy download. On Linux/Unix you can extract the .tar.gz file as follows:
tar xvzf daisy-<version>.tar.gz
On non-Linux unixes (Solaris notably), use the GNU tar version if you experience problems extracting.
On Windows, use the .zip download, which you can extract using a tool like WinZip.
After extraction, you will get a directory called daisy-<version>. This directory is what we will call from now on the DAISY_HOME directory. You may set a global environment variable pointing to that location, or you can do it each time in the command prompt when needed.
