is a considerably slower and less efficient design. Efforts have been made recently
to improve this behaviour.
As of the 1.1 series, pkgconf also fully implements support for `Provides` rules,
while pkg-config does not. pkg-config only provides the `--print-provides` functionality

resolver verses pkg-config's dependency resolver in terms of completeness and correctness,
such as, for example, how `Conflicts` rules are processed.
