# Copy and Paste the text of this script into a text editor and save 
# it as the file sakc in your home area bin folder (~/bin/sakc).
# This script must be marked executable to be used.  Please run 
# the following Terminal command: chmod +x ~/bin/sakc
# To use sakc, download the latest kernel source files from ...
# http://www.kernel.org/ into your download(s) folder.
# Open up a terminal session, change to your download(s) folder
# and run the command: sakc kernel_name
#

# Make Sure the Following Folder/File names are correct and exist!!!

# Where do you Keep/Download Your Kernel Source Files? This Folder Name Must Exist!
