# 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.
