   • The download is about 81kb and will only take a few seconds over a modem, and a lot less over a broadband connection.
   • If you are using a download accelerator program, it will save the file to your default download directory.
2. Download the Gettext source code from www.gnu.org/directory/gettext.html.
   • Visit www.gnu.org/directory/gettext.html and click on the "Source tarball" link.
   • Click on the link for the source code of the latest version of Gettext. You will need the source code in .tar.gz format.
     • At the time of writing the latest version of Gettext was version 0.11.5, so the file downloaded was gettext-0.11.5.tar.gz.
   • You will be asked to where you wish to save the file. Chose a safe place and make a note of it.
   • The download is about 3.5Mb and will take about half an over a modem, but a lot less over a broadband connection.
   • If you are using a download accelerator program, it will save the file to your default download directory.
3. Download the Linux_logo compatible Core Linux Logo from here.
   • You will be asked to where you wish to save the file. Chose a safe place and make a note of it.
   • The download is about 2kb and will only take a second or two over a modem, and a lot less over a broadband connection.
   • If you are using a download accelerator program, it will save the file to your default download directory.
4. Burn the files linux_logo-4.05.tar.gz, gettext-0.11.5.tar.gz and core.logo to a CD. This page assumes that the subdirectory /apps is used for the files. The CD-ROM can be a multi-session disk.
   • Use your CD burning software to create an ISO9660 disc image with the files linux_logo-4.05.tar.gz, gettext-0.11.5.tar.gz and core.logo in the /apps directory.
   • Burn the CD and verify the data stored on it.
