+# SYNOPSIS
+#
+#   Universally Linkable Weak Functions
+#
+# DESCRIPTION
+#
+#   This package contains no-op implementations for (1) synthetic
+#   compiler surprises and (2) mission-critical core functions, e.g.
+#   abort(). These functions are designed to work in all addressing
+#   modes, including real mode. Every package links this. It's at the
+#   base of the topological order of things.
