Description: kernel modules for kernel @@KERNELVERSION@@
  This package contains almost all of the kernel modules that might be
  useful within familiar. Eventually I would like to split many of
  these modules off into their own packages that would have dependency
  links from the programs that need them. For example, e2fsprogs could
  depend on e2fs-kernel-modules or something like that. I have already
  split off cpu-scale and the pcmcia modules into their own packages.
