+# Gentoo defaults for rubygems 3.x
+#
+# Gentoo policy is to install all manually installed code into
+# /usr/local and to keep /usr managed by Gentoo. This policy file
+# ensures that all manually installed gems using "gem install" as root
+# are installed in /usr/local. Gentoo gems are installed in /usr.
+
+# TODO: We used to manipulate the default_dir, but this no longer
+# works since this is now the base for the new "default" gems that
+# ruby 2.6 uses with irb. So default_dir should refer to the system
+# default now. rubygems also provides various hooks so we may be able
+# to use those to install gems in /usr/local by default in a less
+# intrusive way.
