# If `prev` already contains `sdbus-cpp_2`, do not modify the package set.
# If the previous fixpoint does not contain the attribute,
# create a new package attribute, `sdbus-cpp_2` by overriding `sdbus-cpp`
# from `final` with the new version of `src`.
#
# This matches the naming/versioning scheme used in `nixos-unstable` as of writing (10-27-2024).
#
# This overlay can be applied to either a stable release of Nixpkgs, or any of the unstable branches.
# If you're using an unstable branch (or a release one) which already has `sdbus-cpp_2`,
# this overlay is effectively a wrapper of an identity function.
#
# TODO: Remove this overlay after the next stable Nixpkgs release.
