Comment 1 for bug 2066262

Running lintian...
W: libdex source: newer-standards-version 4.7.0 (current is 4.6.2)
W: libdex-doc: stray-devhelp-documentation [usr/share/doc/libdex-1/libdex-1.devhelp2]
I: libdex-doc: possible-documentation-but-no-doc-base-registration
P: libdex source: package-does-not-install-examples [examples/]

All of these can be ignored. The latest Debian Policy is 4.7.0 but lintian has not been updated since that version was released. https://tracker.debian.org/pkg/debian-policy

The devhelp warning is a false warning. Many GNOME modules have switched to gi-docgen to build help and it does things differently that the older gtk-doc-tools. The devhelp app was updated to support devhelp2 files being located in this location.

doc-base is a Debianism that I believe to only barely be used.

The examples are built during the build but are intentionally not installed per upstream's meson.build
