cat << EOF
WARNING:
The kmerge script merges the ALSA driver into the kernel by
creating symbolic links to files in the alsa-driver source
tree.
DO NOT delete this source tree, as this will upset the kernel
and other things such as /usr/include/sound/ which the library
et al looks for.
Experienced users: If you want to delete this, make sure
to copy all the needed includes et al into the proper areas
of $KDIR FIRST.
If you want to delete your kernel sources, make sure to copy
the includes to /usr/include/sound, otherwise alsa-lib and
other programs will scream at you :)
