+# PACKAGING NOTES
+
+# 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 use llvm-utils.eclass directly due to chromium's inherent Googliness.
+
+# 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.
+
+# For binhost users, if USE=bindist is set, we configure Chromium in a way that it is able
+# to use proprietary codecs, and so that ffmpeg is an external component (libffmpeg.so),
+# then we remove ffmpeg from the image to ensure that the built package is distributable
+# (i.e. we don't owe royalties). A suitable libffmpeg.so is symlinked in its place;
+# as a result of this, ffmpeg[chromium] or ffmpeg-chromium must be installed on the system.
+
+# For non-binhost builds, we build the bundled ffmpeg and enable proprietary codecs because there's
+# no reason not to. Todo: Re-enable USE=system-ffmpeg.
