+WHAT IS Linux-libre?\
+\
+ Linux-libre is a Free version of the kernel Linux (see below),\
+ suitable for use with the GNU Operating System in 100% Free\
+ GNU/Linux-libre System Distributions.\
+ http://www.gnu.org/distros/\
+\
+ It removes non-Free components from Linux, that are disguised as\
+ source code or distributed in separate files. It also disables\
+ run-time requests for non-Free components, shipped separately or as\
+ part of Linux, and documentation pointing to them, so as to avoid\
+ (Free-)baiting users into the trap of non-Free Software.\
+ http://www.fsfla.org/anuncio/2010-11-Linux-2.6.36-libre-debait\
+\
+ Linux-libre started within the gNewSense GNU/Linux distribution.\
+ It was later adopted by Jeff Moe, who coined its name, and in 2008\
+ it became a project maintained by FSF Latin America.\
+\
+ The Linux-libre project takes a minimal-changes approach to cleaning\
+ up Linux, making no effort to substitute components that need to be\
+ removed with functionally equivalent Free ones. Nevertheless, we\
+ encourage and support efforts towards doing so.\

+\
+ Our mascot is Freedo, a light-blue penguin that has just come out\
+ of the the shower. Although we like penguins, GNU is a much\
+ greater contribution to the entire system, so its mascot deserves\
+ more promotion. See our web page for their images.\
