I'm trying to understand how bitbake parses the poky directory tree a little better.

The best I can figure all .bb files are NOT included. Just some of them are. I'm guessing that the .bb in the meta/recipe-sato named is the one that is used to start the parsing if bitbake core-image-sato is executed.
I originally thought all subdirectories of a path included in BBLAYER were parsed looking for .bb files, but now I know that is not true, but not sure why.

For example, it does not appear that webkit is included in the core-image-sato even though the recipe-sato directory includes the webkit subdirectory with it's recipe. What would be the proper way of adding the webkit to core-image-sato??
The 'webkit' is just a library used to build tools such as a
web browser. You might want to start with an application that
actually uses webkit, such as web-webkit.

To build an image which includes web-webkit, add this line to
your local.conf file and rebuild the image:
IMAGE_INSTALL += "web-webkit"

You can also build packages which are not installed into your
image by default and use a package manager (e.g. zypper) to
install the package later onto a running system.
This was very helpful. Before I got your email, I had gotten the advice to
put the IMAGE_INSTALL += "web-webkit" into the file.
Both seem to work. Not sure which is the best approach. Maybe creating a .bbappend
in my BSP??

So how do I know which applications are installed in an image? is there a how file of IMAGE_INSTALL statements?
