+@code{TextMapPropagator} creation function.  The @code{OpenTelemetry}
+specification states that the default @code{TextMapPropagator} needs to be a
+no-operation implementation.  The opentelemetry-go project adheres to this
+requirement.  However, for systems that perform propagation this default is
+not ideal.  This package provides a @code{TextMapPropagator} with useful
+defaults (a combined @code{TraceContext} and Baggage
+@code{TextMapPropagator}), and supports environment overrides using the
+OTEL_PROPAGATORS environment variable.")
