# Rebuilds a tree of directories containing a System.map, .config (renamed
# config), and kernel (vmlinux).  The input is a tree of directories
# beneath the current one with names matching the wildcard *.?
# (in Slackware, these will typically be *.s for IDE/SCSI kernels).  At the
# minimum, each directory must contain the file 'config', which is the
# .config to start with when building the kernel.
