 Slackware @LIVEDE@ Live Edition has been installed to your hard drive!
 We installed the ${ACT_MODS} active modules (out of ${TOT_MODS} available).
 If present, the following files were copied from the Live OS to your harddisk:
   /etc/profile.d/lang.sh

 After finishing system configuration and before rebooting, you can add any further Live modules from /@LIVEMAIN@/addons/ and /@LIVEMAIN@/optional/ to your hard drive, using a command similar to this:
