+ [Arnaud]
+ - Add an implementation of the contexts using pthread
+
+ [Martin]
+ (misc)
+ - Add xbt_procname(): returns the name of the current process.
+ Use it to show the current process's name in all logging.
+ (infrastructure)
+ - fix detection of older flex version and the reaction, since we do
+ depend on modern ones (we use lex_destroy)
+ - Better separation of SG and RL in the libs: remove all simulation code
+ from libgras. As a result, this lib is now only 200k when stripped.
+ Some of the xbt modules may also be duplicated (two sets and such) and
+ should be cleaned/killed before SG3.
+ (msg)
+ - Add MSG_task_get_name. The task names are mainly for debugging purpose,
+ but anyway.
