[oe] Where does the package name is defined?

[aaa]

Hi OE,


I am a newbie to OE, trying to reading the UserManual of the OE.
There are a set of bitbake targets named as PAKAGE-image,which has a "image" suffix,  like helloworld-image, bootstrap-image, but there is only "helloworld" under the ${OEBASE}/openembedded/recipes/, my question is where is the helloworld-image(which has a image suffix) defined?


Thanks in advance!
Biao
