+# Google roll their bundled Clang every two weeks, and the bundled Rust
+# is rolled regularly and depends on that. While we do our best to build
+# with system Clang, we will eventually hit the point where we need to use
+# the bundled Clang due to the use of prerelease features. We've been lucky
+# enough so far that this hasn't been an issue.
+
+# We try and avoid forcing the use of libcxx, but sometimes it is unavoidable.
+# Remember to force the use of Clang when this is forced.
+
+# GCC is _not_ supported upstream, though patches are welcome. We do our
+# best to enable builds with GCC but reserve the right to force Clang
+# builds if we can't keep up with upstream's changes. Please comment
+# when forcing Clang builds so we can track the need for it.
+
+# GN is bundled with Chromium, but we always use the system version. Remember to
+# check for upstream changes to GN and update ebuild (and version below) as required.
+
+# These variables let us easily bound supported major dependency versions in one place.
