-    GTK supports profiling with sysprof. It exports timing information
-    about frameclock phases and various characteristics of GskRenders
-    in a format that can be displayed by sysprof or GNOME Builder.

-  <para>
-    A simple way to capture data is to set the <envar>GTK_TRACE</envar>
-    environment variable. When it is set, GTK will write profiling
-    data to a file called
-    <filename>gtk.<replaceable>PID</replaceable>.syscap</filename>.
-  </para>
-  <para>
-    When launching the application from sysprof, it will set the
-    <envar>SYSPROF_TRACE_FD</envar> environment variable to point
-    GTK at a file descriptor to write profiling data to.
-  </para>
-  <para>
-    When GtkApplication registers with D-Bus, it exports the
-    <literal>org.gnome.Sysprof2.Profiler</literal> interface
-    that lets sysprof request profiling data at runtime.
