+# CAVEAT LECTOR: This PKGBUILD is highly opinionated. I give you
+#                enough rope to hang yourself, but by default it
+#                only enables the features I use.
+#
+#        TLDR: yaourt users, cry me a river.
+#
+#        Everyone else: do not update blindly this PKGBUILD. At least
+#        make sure to compare and understand the changes.

+# Take note that I don't expect you to track anything different to master
