How can i know the meaning of options when I configure the Fiasco kernel

[chenggh]

Hi:
	Now I could boot the fiasco, l4linux and l4dope. In other words I could start 
to use drops system. But I want to know deep about the system especially the 
meanings of configuration options. 
	In the menuconfig of fiasco kernel the help command says I could input the 
symbol of "?" to get the description of options. But it seems that it can't 
work well.
	Thank you.
