 122
 123   --destdir=DESTDIR
 124     Root directory to install into (like DESTDIR with auto*).
 125

 146     Directory containing linux source tarballs.

 157     Specifies a special option (such as smp, bigsmp, bigmem, or BOOT)
 158     to use when choosing a kernel config file.  This also modifies the
 159     kernel version and modules directory.
