NAME
     mmkkeexxttuunnppaacckk - extracts the contents of a multikext (mkext) archive

SYNOPSIS
     mmkkeexxttuunnppaacckk [-vv] [-aa arch] [-dd outputdirectory] mkextfile

DESCRIPTION
     The mmkkeexxttuunnppaacckk program list the contents of a multikext file,
     mkextfile, or unarchives the contents into outputdirectory (which must
     exist).  The -vv option causes mmkkeexxttuunnppaacckk to print the name if each kext
     as it finds them.

DIAGNOSTICS     mmkkeexxttuunnppaacckk exits with a zero status upon success.  Upon failure, it
     prints an error message and exits with a nonzero status.

     With a nonsegreated mkext file, wherein each kext may contain a universal
     binary, mmkkeexxttuunnppaacckk simply unpacks the contents.  With an mkext file seg-
     regated by architecture (that is, with distinct internal archives of
     architecture-specific kexts), mmkkeexxttuunnppaacckk attempts by default to unpack
     or list kexts for the current machine's architecture.  To choose a par-
     ticular architecture to extract or list, use the -aa option.

     There is no simple way to unpack a segregated mkext file into a set of
     kexts with universal binaries, but you can unpack each of its component
     architectures to separate directories for examination.

BUGS
     The mkext file format doesn't record the original filenames of the kexts,
     so mmkkeexxttuunnppaacckk has to guess at what they are.  It does this by using the
     value of the CFBundleExecutable property of the kext's info dictionary
     (Project Builder sets this to the base name of the kext bundle by
     default, but the developer can change it).  If that property doesn't
     exist, the last component of the CFBundleIdentifier is used.  Duplicates
     have an incrementing index appended to the name.  Kexts that have no
     CFBundleExecutable or CFBundleIdentifier property are named
     ``NameUnknown-n.kext'', where n is a number.
