+@section msg_ex_process Acting on Processes
+
+ - <b>Suspend and Resume processes</b>.
+ @ref examples/msg/process-suspend/process-suspend.c \n
+ Processes can be suspended and resumed during their executions
+ thanks to the @ref MSG_process_suspend and @ref MSG_process_resume functions.
+
+ - <b>Kill processes</b>.
+ @ref examples/msg/process-kill/process-kill.c \n
+ Processes can forcefully stop other processes with the @ref MSG_process_kill function.
+
+ - <b>Migrating processes</b>.
+ @ref examples/msg/process-migration/process-migration.c \n
+ Processes can move or be moved from a host to another with the @ref MSG_process_migrate function.
+
+ - <b>Controling the process life cycle from the XML</b>.
+ @ref examples/msg/process-startkilltime/process-startkilltime.c \n
+ You can specify a start time and a kill time in the deployment
+ file. See all *_d.xml files in this directory.
+
+@section msg_ex_tracing Tracing and visualization features
+
+Tracing can be activated by various configuration options which
+are illustrated in these example. See also the
+@ref tracing_tracing_options "full list of options related to tracing".
+
+ - <b>Basic example</b>. @ref examples/msg/trace-simple/trace-simple.c \n
+ In this very simple program, each process creates, executes,
+ and destroy a task. Recommanded options:
+ @verbatim --cfg=tracing:yes --cfg=tracing/uncategorized:yes @endverbatim
+
+ - <b>Platform tracing</b>.
+ @ref examples/msg/trace-platform/trace-platform.c \n
+ This program is a toy example just loading the platform, so that
+ you can play with the platform visualization. Recommanded options:
+ @verbatim --cfg=tracing:yes --cfg=tracing/categorized:yes
+ @endverbatim
+
+ - <b>Setting Categories</b>.
+ @ref examples/msg/trace-categories/trace-categories.c \n
+ This example declares several tracing categories
+ to that are used to classify its tasks. When the program is executed,
+ the tracing mechanism registers the resource utilization of hosts
+ and links according to these categories. Recommanded options:
+ @verbatim --cfg=tracing:yes --cfg=tracing/categorized:yes --cfg=tracing/uncategorized:yes --cfg=viva/categorized:viva_cat.plist --cfg=viva/uncategorized:viva_uncat.plist
+ @endverbatim
+
+ - <b>Master Workers tracing</b>.
+ @ref examples/msg/trace-masterworker/trace-masterworker.c \n
+ This is an augmented version of our basic master/worker example
+ using several tracing features. It traces resource usage, sorted
+ out in several categories; Trace marks and user variables are also
+ used. Recommanded options:
+ @verbatim --cfg=tracing/categorized:yes --cfg=tracing/uncategorized:yes --cfg=viva/categorized:viva_cat.plist --cfg=viva/uncategorized:viva_uncat.plist
+ @endverbatim
+
+ - <b>Process migration tracing</b>.
+ @ref examples/msg/trace-process-migration/trace-process-migration.c \n
+ This version is enhanced so that the process migrations can be
+ displayed as arrows in a Gantt-chart visualization. Recommanded
+ options to that extend:
+ @verbatim -cfg=tracing:yes --cfg=tracing/msg/process:yes
+ @endverbatim
+
+@subsection msg_ex_tracing_user_variables Tracing user variables
+
+You can also attach your own variables to a any resource described in
+the platform file. The following examples illustrate this feature.
+They have to be run with the following options:
+@verbatim --cfg=tracing:yes --cfg=tracing/platform:yes
+@endverbatim
+
+ - <b>Attaching variables to Hosts</b>.
+ @ref examples/msg/trace-user-variables/trace-user-variables.c
+
+ - <b>Attaching variables to Links</b>.
+ @ref examples/msg/trace-link-user-variables/trace-link-user-variables.c \n
+ The tricky part is that you have to know the name of the link you
+ want to enhance with a variable.
+
+ - <b>Attaching variables to network Routes</b>
+ @ref examples/msg/trace-link-srcdst-user-variables/trace-link-srcdst-user-variables.c \n
+ It is often easier to update a given variable for all links of a
+ given network path (identified by its source and destination
+ hosts) instead of knowing the name of each specific link.
