+IMPORTANT NOTE FOR USERS OF FEBOOTSTRAP 2.x:
+ febootstrap 3.x is a complete rewrite. febootstrap 2.x could only

+ of Linux distros. 3.x only builds supermin appliances, it does not
+ build chroots. 3.x does not build cross-distro, cross-release or
+ cross-architecture systems. If you want febootstrap 2.x, please use
+ the 'febootstrap-2.x' branch from the git repository.
