commit 2bb96d275930fd7d1efcdc02803f28dc6ccecb6a

    Lzip's output piped into Tar in book's quick start
    
    Antonio Diaz Diaz kindly noted that for systems where Tar doesn't recognize
    `.tar.lz', we can use a pipe instead of two commands. So a footnote was
    added to the "Quick start" section of the book to remind the users of this
    method. In the main text, the two command format is kept because it is more
    clear to the un-experienced eyes.
    
    An experienced person in the Unix-way will never even open this section of
    the book, they will have their own methods to uncompress and un-pack a
    tarball. But the footnote can be a good reminder for a person who is
    reading the manual a second time (and has gained some prior experience in
    Unix).
