==== What is SPKG ====
	SPKG, means Stupid PacKaGe tool.
	SPKG can package a directory to a single executable "*.sh" file.
Let us just call this "*.sh" file as "spkg file". The spkg file can 
unpackage it self by just execute it with "spkg-unpackage" option.
	Even more, if you just execute the spkg file without "spkg-package" 
either "spkg-unpackage" option, the files in it will be unpackage to /tmp, 
and the "spkg-entry.sh" script will be executed.
	NOTICE: After spkg-entry.sh exit, all of the files which be unpackage 
to /tmp will be deleted. So, keep you spkg-entry,sh running!

==== Usage ====
spkg.sh spkg-package <DIR>	The <DIR> will be package to DIR.sh.
spkg.sh spkg-unpackage		The files in spkg file will be unpackage.
spkg.sh [OPTIONS]		The [OPTIONS] is optional. All OPTIONS will be 
		passed to spkg-entry.sh when execute it.

PS1:
	When making a package, there has will be an editer such as vim, 
opening spkg-entry.sh. Don't panic, just input what you want to do after 
unpackage.
PS2:
	spkg file has self-reproduction. It means that if you got a package 
named "A.sh" using "spkg.sh", then you can get a package named "B.sh" using 
"A.sh", without "spkg.sh". After that, you can get a package named "C.sh" 
using "A.sh" or "B.sh"...

==== TO DO ====
	spkg-install OPTION.
	spkg-uninstall OPTION.
