-** Source tree organization
-**
-******************************************************
-
-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.
-
-**
-** 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
-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)
- - 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:
- 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.
-
-If you see any part of the code not following this convention, this is a
-bug. Please report it (or fix it yourself if you can).

-** Random bits about coding standards and portability
-**
-*****************************************************
-
-MALLOC:
- You must cast the result of malloc on AIX.
- It's even better to use gras_new when possible.
-
-SIZE_T
- If possible, avoid size_t and use unsigned long instead. If not,
-
- #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));
