#   $1 - kernel version (ie. 2.6.32-zen2)
#   $2 - kernel image file (bzImage)
#   $3 - kernel map file (System.map)
#   $4 - default install path (usually /boot)

# instead of $4 we change the path here. i couldn't figure out how to change it in 'make install'.
# if you just want to use $4 as the path, uncomment the line below and comment the other _path line below.
