VOCAL software is available on the http://Vovida.org web site as a Linux source file, vocal-1.3.0.tar.gz. The tarball is more than 21 MB in size and, depending on your connection speed, downloading this file could require a few minutes, a few hours, or, hopefully not, a few days. To find this file on http://Vovida.org, go to the VOCAL home page and look for the link under Source Code.
While we were completing the final draft of this book, Version 1.4.0 of VOCAL was released on http://Vovida.org. Version 1.4.0 gives you the option of installing VOCAL without a Java requirement: using a simple HTTP Provisioning interface to add users instead of the GUI described in Chapter 4. There are also RPM files available that enable you to bypass the compiling stage of the installation.
Go to http://Vovida.org for more information about installing Version 1.4.0 along with more commentary about some of the other changes found in that release. The majority of the effort that went into Version 1.4.0 was directed towards simplifying the installation process. No significant changes were made to the servers.
