XBT_log, \ref XBT_ex and \ref XBT_config.
XBT also encompass the following convenient C data structures:
-\ref XBT_dynar, \ref XBT_fifo, \ref XBT_dict, \ref XBT_heap, \ref XBT_set and
+\ref XBT_dynar, \ref XBT_dict, \ref XBT_heap, and
\ref XBT_swag. The code is being migrated in C++ so you should probably want
to use standard C++ containers instead of them if possible.
