I'm having a hard time double-guessing how my package's .appdata.xml is
processed at the distro level (I presume, by appstream-builder).
I validated it with fedpkg already, but there are lots of undetected
issues, such as restricted icon search path, same-package constraints, etc.
Is there a log of how the AppStream Collection Metadata for Fedora is
generated, so I can look for errors?
(alternatively is there an easy way to pre-test this locally?)
