"GRUB 2 has been rewritten from scratch to clean up everything for"
"modularity and portability."
"Features are: Scripting support, Graphical interface, Rescue mode,"
"cross-platform and many more"
"Briefly, boot loader is the first software program that runs when a"
"computer starts. It is responsible for loading and transferring"
"control to the operating system kernel software (such as the Hurd or"
"the Linux). The kernel initializes the rest of the operating system."
"* gettextvar, eval, getdate commands added."
