+ * is stored as an M4 file  (atomlist.m4) where each Atom is stored as
+ * a variable defined in the header.
+ *
+ * Replies of requests generating a  list of pointers (such as list of
+ * windows, atoms and UTF-8 strings)  are simply stored as a structure
+ * holding  the XCB  reply which  should (usually)  never  be accessed
+ * directly and has  to be wipe afterwards. This  structure provides a
+ * convenient access to the list given in the reply itself.
+ *
+ * \todo Add  missing prototypes but  asks for advices on  XCB mailing
+ *       list before.
