I wish to add more python modules to my yocto/openembedded project but I am unsure how to?  I wish to add flask and its dependencies.
The OE layer index at layers.openembedded.org lists all known layers and the recipes they contain, so searching that should bring up the meta-python layer that you can add to your build and use recipes from.
How do I add more python modules to my yocto/openembedded project?
