******************************************************
-There is 4 projects in the tree:
-
- - GROS: no fancy name yet (low-level toolbox: logging, datatypes).
- - GRAS: Grid Reality And Simulation (message passing API with two
- implementations allowing to compile programs on top of the
- simulator or for the real life without code modification)
- - SURF: Server for the Use of Resource Fictions (the simulator used
- in GRAS and more)
- - AMOK: Advanced Metacomputing Overlay Kit (high level toolbox; Grid
- application elements such as distributed database, topology
- discovery service, and so on)
-
-They are all in the same tree because GRAS depends on SURF which depends on
-GRAS (that's the only cycle here, we're not *that* vicious).
-
-The tree is not splited on projects, but on file finality:
- include/ -> all *public* headers
- include/gros/*.h -> one file per module
- include/gros.h -> file including all modules headers
- (same for gras, surf and amok instead of gros)
-
- src/Makefile.am -> main makefile. All projects should fit in only one
- library (I mean 2, RL+SG), which is compiled here.
-
- Since all object.o files are placed here, you should
- choose the name of c files carfully to avoid
- conflict.
-
- src/gras/DataDesc -> typical project module
- src/gras/DataDesc/datadesc_interface.h -> visible to any GRAS modules;
- masked to the user and GROS/AMOK/SURF
- src/gras/DataDesc/datadesc_private.h -> visible only from this module
-
- So, the modules have 3 levels of publicity for their interface.
- Private, internal to GRAS, public. Of course, I try to keep as much stuff
- private as possible.
-
- testsuite/ -> The more test the better.
- Same organization than src/ and include/
- Tests are allowed to load some headers of the module they test.
- All tests should be listed in run_test.in so that they get
- run on 'make check'.
- They are not listed directly in the check_PROGRAMS part of
- the makefile because run_test knows about the gras logging
- features and relaunch with full details the failed tests.
-
examples/ -> Supposed to be copy/pastable by the user, so keep it clear and
avoid any kind of trick. In particular, do only include the
public headers here.
+ teshsuite/ -> The more test the better. Put in there any strange test
+ doing things that the users are not supposed to do,
+ just to see if our framework is robust to incorrect and
+ unusual behaviors. All tests written in this section
+ should leverage our tesh(1) utility.

** Type naming standard
**
*****************************************************
It may sound strange, but the type naming convention was source of intense
-discution between da GRAS posse members. The convention we came to may not
+discussion between da SimGrid posse members. The convention we came to may not
be the best solution, but it has the merit to exist and leave everyone work.
So please stick to it.
- - ???_t is a valid type (builded with typedef)
+ - ???_t is a valid type (built with typedef)
- s_toto_t is a structure (access to fields with .)
- s_toto is a structure needing 'struct' keyword to be used
- e_toto_t is an enum
- u_toto_t is an union
- u_toto is an union needing 'union' keyword to be used
- toto_t is an 'object' (struct*)
-
+
Please to not call toto_t something else than an 'object' (ie, something you
have to call _new and _free on it).
-Exemple:
+Example:
typedef struct s_toto {} s_toto_t, *toto_t;
typedef enum {} e_toto_t;
-
+
Moreover, only toto_t (and e_toto_t) are public. The rest (mainly s_toto_t)
is private.

-*****************************************************
+****************************************************
+
+The global structure of the documentation is in doc/modules.doc
+
+The structure of each module (xbt, msg, etc) is in doc/module-<module>.doc
+
+The structure of a module is in its public header. This way, you're sure to
+see all the public interface (and only it). The different parts of the
+interface are grouped using the @name construct, even if it's buggy. Since
+parts often get reordered, it's better to add numbers to the parts (so that
+users can see the intended order).
+
+The documentation of each type and macro are also in the public header since
+this is were they live.
-MALLOC:
- You must cast the result of malloc on AIX.
- It's even better to use gras_new when possible.
+The documentation of each function must be in the C file were it lives.
-SIZE_T
- If possible, avoid size_t and use unsigned long instead. If not,
+Any public element (function, type and macro) must have a @brief part.
- #include <sys/types.h> in all files manipulating size_t
- do cast it to unsigned long before printing (and use %lu)
-
-PRINTF pointer difference
- printf ("diff = %ld\n", (long) (pointer2 - pointer1));
