EXERCISE STEPS

0 Get the newest os lab src codes/docs.(Insure you can connect to github in ubuntu running on VrtualBox)
0.1 If you try to get all codes
  $rm -rf ucore_lab
  $git clone git://github.com/chyyuu/ucore_os_lab.git
  $cd ucore_lab
0.2 If you gloned ucore_lab and only try to get the updated codes
  $cd ucore_os_lab
  $git pull
1 $cd labX  
2 read codes (specially the modified or added files)
3 add your code
4 compile your code
  $make
5 check your code
  $make qemu
OR
  $make grade

6 debug your code
  $make debug

7 handin your code
  $make handin

OPTION

Now, ucore suuport LLVM/Clang-3.5 + in step4: $ USELLVM=1 make then you will use clang to compile ucore
