+Adding configuration flags into the platform file is particularly
+useful when the described platform is best used with specific
+flags. For example, you could finely tune SMPI in your platform file
+directly. Almost all :ref:`command-line configuration items <options_list>`
+can be configured this way.

- At time t=4, the bandwidth is of 40 MBps.
- At time t=8, it raises to 60MBps.
From your code, you can interact with these properties using the
following functions:
+
+- Actor: :cpp:func:`simgrid::s4u::Actor::get_property` or :cpp:func:`MSG_process_get_property_value`
+- Cluster: this is a zone, see below.
- Host: :cpp:func:`simgrid::s4u::Host::get_property` or :cpp:func:`MSG_host_get_property_value`
+- Link: :cpp:func:`simgrid::s4u::Link::get_property`
+- Storage: :cpp:func:`simgrid::s4u::Storage::get_property` or :cpp:func:`MSG_storage_get_property_value`
+- Zone: :cpp:func:`simgrid::s4u::Zone::get_property` of :cpp:func:`MSG_zone_get_property_value`
