## other differences verses pkg-config
As previously mentioned, pkgconf makes optimizations to the linker flags in both the
case of static and shared linking in order to avoid overlinking binaries and also
simplifies the `CFLAGS` and `LIBS` output of the pkgconf tool for improved readability.
This functionality depends on the pkg-config module properly declaring it's dependency
tree instead of using `Libs` and `Cflags` fields to directly link against other modules
which have pkg-config metadata files installed.
Doing so is discouraged by the [freedesktop tutorial][fd-tut] anyway.

Beyond that, we do not provide bug-level compatibility with pkg-config. What that means
is, if you feel that there is a legitimate regression verses pkg-config, do let us know,
but also make sure that the .pc files are valid and follow the rules of the
[pkg-config tutortial][fd-tut], as most likely fixing them to follow the specified
rules will solve the problem.
