[yocto] The difference of & and | in LICENSE definition

[Kumita Bruce]

Hi,

I don't know whether this is the right place to ask the question. Hope to
get some help from here.

I see below two types definition of LICENSE in Yocto recipe:
LICENSE = "license-1 & license-2"
LICENSE = "license-1 | license-2"

Can somebody help to give some explanation for the difference of those two
formats? And how to determinate which format should be used for a package.


Cheers,

Bruce
