produce good platform and some choices you can make in order to have
faster simulations. Here's some hints and tips, then.
+@subsection Finding the platform example that you need
+
+Most platform files that we ship are in the @c examples/platforms
+folder. The good old @c grep tool can find the examples you need when
+wondering on a specific XML tag. Here is an example session searching
+for @ref pf_trace "trace_connect":
+
+@verbatim
+% cd examples/platforms
+% grep -R -i -n --include="*.xml" "trace_connect" .
+./two_hosts_platform_with_availability_included.xml:26:<trace_connect kind="SPEED" trace="A" element="Cpu A"/>
+./two_hosts_platform_with_availability_included.xml:27:<trace_connect kind="HOST_AVAIL" trace="A_failure" element="Cpu A"/>
+./two_hosts_platform_with_availability_included.xml:28:<trace_connect kind="SPEED" trace="B" element="Cpu B"/>
+./two_hosts.xml:17: <trace_connect trace="Tremblay_power" element="Tremblay" kind="SPEED"/>

\subsection pf_as_h AS Hierarchy
The AS design allows SimGrid to go fast, because computing route is
done only for the set of resources defined in this AS. If you're using
