+
+This configuration option sets a breakpoint: when the simulated clock reaches
+the given time, a SIGTRAP is raised. This can be used to stop the execution and
+get a backtrace with a debugger.
+
+It is also possible to set the breakpoint from inside the debugger, by writing
+in global variable simgrid::simix::breakpoint. For example, with gdb:
+
+\verbatim
+set variable simgrid::simix::breakpoint = 3.1416
