NAME

       qb-blackbox - Display "flight data" from the "blackbox".

SYNOPSIS

       qb-blackbox [blackbox-file...]

DESCRIPTION

       qb-blackbox  prints  out  the logs (including debug logs) that were recorded using libqb's
       blackbox mechanism.

   Portability notes
       Due to variations amongst platforms, some of which directly impact  the  libqb's  blackbox
       format  handling  (e.g. page size), there's currently only the commitment that qb-blackbox
       shall decode the blackbox files recorded at the same platform (plus the  same  page  size)
       while   using   libqb   compiled   with  the  same  relevant  compile-time  options  (e.g.
       USE_CACHE_LINE_ALIGNMENT) as linked to this decoder.  Otherwise, your mileage may vary.
