This script will download the newest version of MiniMyth and update your tftp directory.

It first downloads the version file and compares that version number to the current install version of MiniMyth install.  If it determines that the version dose not match it will then download the current release, untar it and move the files to their current locations. It dose not delete any older versions on your server.

• The TFTPDIR variable is the location on your tftp server where the MiniMyth files are stored.
• The URL variable is the MiniMyth directory that the install of MiniMyth you wish to use lives.

You may also download the full directory structure with this script from my github repository or from my server.
