+ * @brief Describing data to be exchanged
*
* Since GRAS takes care of potential representation conversion when the platform is heterogeneous,
* any data which transits on the network must be described beforehand.
*
* There is several possible interfaces for this, ranging from the really completely automatic parsing to
- * completely manual. Let's study each of them from the simplest to the more advanced.
+ * completely manual. Let's study each of them from the simplest to the more advanced:
*
- * \warning At least, I would like to present those sections in the right order, but doxygen prevents me
- * from doing so. There is a weird bug I fail to circumvent here. The right order is naturally:
- * -# basic operations
- * -# Automatic parsing
- * -# Simple manual definitions
- * -# Callback Persistant State: Simple push/pop mechanism
- * -# Callback Persistant State: Full featured mechanism

-/** @name 1. basic operations
+ * - Section \ref GRAS_dd_basic presents how to retrieve and use an already described type.
+ * - Section \ref GRAS_dd_auto shows how to get GRAS parsing your type description automagically. This
+ * is unfortunately not always possible (only works for some structures), but if it is for your data,
+ * this is definitly the way to go.
+ * - Section \ref GRAS_dd_manual presents how to build a description manually. This is useful when you want
+ * to describe an array or a pointer of pre-defined structures.
+ * - You sometimes need to exchange informations between descriptions at send or receive time. This is
+ * for example useful when your structure contains an array which size is given by another field of the
+ * structure.
+ * - Section \ref GRAS_dd_cb_simple provides a simple interface to do so, allowing to share integers stored on a stack.
+ * - Section \ref GRAS_dd_cb_full provides a full featured interface to do so, but it may reveal somehow difficult to use.

* If you only want to send pre-existing types, simply retrieve the pre-defined description with
* the \ref gras_datadesc_by_name function. Existing types entail:
* Example:\verbatim gras_datadesc_type_t i = gras_datadesc_by_name("int");
gras_datadesc_type_t uc = gras_datadesc_by_name("unsigned char");
gras_datadesc_type_t str = gras_datadesc_by_name("string");\endverbatim

*
* If you need to declare a new datatype, this is the simplest way to describe it to GRAS. Simply
* enclose its type definition into a \ref GRAS_DEFINE_TYPE macro call, and you're set. Here is
gras_datadesc_type_t
gras_datadesc_parse(const char *name, const char *C_statement);

* Here are the functions to use if you want to declare your description manually.
* The function names should be self-explanatory in most cases.
