/**
 * \file btrack.c
 * \brief Bootstrap trackers
 *
 * Initializes and shuts down the specific bootstrap trackers.  These
 * trackers help the reporting of bootstrap progress by maintaining
 * state information about various subsystems within tor.  When the
 * correct state changes happen, these trackers emit controller
 * events.
 *
 * These trackers avoid referring directly to the internals of state
 * objects of other subsystems.
 *
 * btrack_circuit.c contains the tracker for origin circuits.
 *
 * btrack_orconn.c contains the tracker for OR connections.
 *
 * Eventually there will be a tracker for directory downloads as well.
