Usage:
     make --generate a kernel floppy Image with a fs on hda1
     make start -- start the kernel in vm (qemu/bochs)
     make start-fd -- start the kernel with fs in floppy
     make start-hd -- start the kernel with fs in hard disk
     make debug -- debug the kernel in qemu/bochs & gdb at port 1234
     make debug-fd -- debug the kernel with fs in floppy
     make debug-hd -- debug the kernel with fs in hard disk
     make disk  -- generate a kernel Image & copy it to floppy
     make cscope -- genereate the cscope index databases
     make tags -- generate the tag file
     make cg -- generate callgraph of the default main entry
     make cg f=func d=dir|file b=browser -- generate callgraph of func in file/directory
     make clean -- clean the object files
     make distclean -- only keep the source code files

Note!:
     * You need to install the following basic tools:
          ubuntu|debian, qemu|bochs, ctags, cscope, calltree, cflow, graphviz 
          vim-full, build-essential, hex, dd, gcc 4.3.2...
     * Becarefull to change the compiling options, which will heavily
     influence the compiling procedure and running result.

Author:
     * 1991, linus write and release the original linux 0.95(linux 0.11).
     * 2005, jiong.zhao<gohigh@sh163.net> release a new version

     features for experimenting. such as this help info, boot/bootsect.s and
     boot/setup.s with AT&T rewritting, porting to gcc 4.3.2 :-)
     * 2011, tigercn<moonlight.yang@gmail.com> port to new system and gcc.
     * 2012, yuanxinyu<yuanxinyu.hangzhou@gmail.com> add Mac OS X support.
     * 2015, falcon <wuzhangjin@gmail.com> back reorganize and maintain it.
