Thanks Ke,

As a style note I'll mention that the usual place to put the entries in 
a recipe is after the SRC_URI line. Example:

http://git.pokylinux.org/cgit/cgit.cgi/poky/tree/meta/recipes-extended/grep/grep_2.7.bb

I tend to put a blank line between the SRC_URI and SRC_URI[checksum] 
fields, but that's just my personal preference. I think it looks best 
especially when a SRC_URI includes several patches.
