       | That's a lot of Perl.

       | Shame that it can't be used much commercially in many cases due
       | to GPLv3 license. This could improve so many embedded systems
       | currently using SquashFS.

         | avoid GPLv3 in any commercial product. Anything GPLv3 will be
         | off my check-out list for anything immediately because I
         | honestly don't know what GPLv3 really means to me. I use GPLv2
         | cautiously wherever it fits as I feel at least I know what it
         | implies.
