create_distro_packages_list() in meta/lib/oe/distro_check.py is the only 
existing code that reads those values that I'm aware of, but that may not be 
in the form that you need it.

One thing you'll definitely need to do is to actually include the file in your 
configuration i.e.:

require conf/distro/include/distro_alias.inc

After that you should just be able to access DISTRO_PN_ALIAS like any other 
recipe-specific variable provided you're doing so in the context of a recipe 
(e.g. within a task for the recipe you wish to query the value for).

Cheers,
Paul
