artifacts:
- Hide the examples into examples/deprecated. New users should use S4U.
- MSG_process_create and MSG_process_attach now crash if the host used
to run this process is off.
+ - Fix the protype of MSG_process_on_exit()
+ Now use (int,void*) callbacks instead of (void*,void*) ones.
+ The implementation was ways too messy to actually work, I guess.
XBT:
- Drop sg_cmdline. Please use xbt_cmdline instead.
- In <host> and <peer>, availability_file is now speed_file.
XML file version remains 4.2 since old files are still compatible.
+Internal:
+ - Many cleanups in the kernel::activity namespace. This was long
+ overdue, and shall open the path to many future endeavors.
+
Fixed bugs:
- #132: Java : a process can not shut down its own host
- #261: Document the parameters of parallel execution's constructor

-As @ref starting_components "explained in the introduction," any
-SimGrid study must entail the description of the platform on which you
-want to simulate your application. You have to describe **each element
-of your platform**, such as computing hosts, clusters, each disks,
-links, etc. You must also define the **routing on your platform**, ie
-which path is taken between two hosts. Finally, you may also describe
-an **experimental scenario**, with qualitative changes (e.g.,
-bandwidth changes representing an external load) and qualitative
-changes (representing how some elements fail and restart over time).
-
-You should really separate your application from the platform
-description, as it will ease your experimental campain afterward.
-Mixing them is seen as a really bad experimental practice. The easiest
-to enforce this split is to put the platform description in a XML
-file. Many example platforms are provided in the archive, and this
-page gives all needed details to write such files, as well as some
-hints and tricks about describing your platform.
-
-On the other side, XML is sometimes not expressive enough for some
-platforms, in particular large platforms exhibiting repetitive
-patterns that are not simply expressed in XML. In practice, many
-users end up generating their XML platform files from some sort of
-scripts. It is probably preferable to rewrite your XML @ref
-platform_lua "platform using the lua scripting language" instead.
-In the future, it should be possible to describe the platform directly
-in C++, but this is not possible yet.
+
As usual, SimGrid is a versatile framework, and you should find the
way of describing your platform that best fits your experimental
practice.
-@section pf_overview Describing the platform with XML
-
-Your platform description should follow the specification presented in
-the [simgrid.dtd](https://simgrid.org/simgrid.dtd)
-DTD file. The same DTD is used for both the platform and deployment
-files.
-
-From time to time, this DTD evolves to introduce possibly
-backward-incompatible changes. That is why each platform desciption is
-enclosed within a @c platform tag, that have a @c version attribute.
-The current version is <b>4.1</b>. The @c simgrid_update_xml program can
-upgrade most of the past platform files to the recent formalism.
-
@section pf_first_example First Platform Example
Here is a very simple platform file, containing 3 resources (two hosts
</platform>
@endcode
-As we said, the englobing @ref pf_overview "<platform>" tag is
-used to specify the dtd version used for this file.
Then, every resource (specified with @ref pf_tag_host, @ref
pf_tag_link or others) must be located within a given **networking
list.

Defining Basic Elements
***********************
+These are the components of your platform.
+
+
There is not much to say about the definition of basic elements. Just
use the appropriate tags: :ref:`pf_tag_host`, :ref:`pf_tag_link` and
:ref:`pf_tag_storage`.
:``state_file``: File containing the state profile.
See the full description in :ref:`pf_tag_host`
+.. _pf_tag_platform:
-
+------------------------------------------------------------------
+<platform>
+------------------------------------------------------------------
+
+**Parent tags:** none (this is the root tag of every file) |br|
+**Children tags:** :ref:`pf_tag_config` (must come first),
+:ref:`pf_tag_cluster`, :ref:`pf_tag_cabinet`, :ref:`pf_tag_peer`,
+:ref:`pf_tag_zone`, :ref:`pf_tag_trace`, :ref:`pf_tag_trace_connect` |br|
+**Attributes:**
+
+:``version``: Version of the DTD, describing the whole XML format.
+ This versionning allow future evolutions, even if we
+ avoid backward-incompatible changes. The current version
+ is **4.1**. The ``simgrid_update_xml`` program can
+ upgrade most of the past platform files to the recent
+ formalism.
