This tag is used to change the default limits of script execution.
The maximum recursion depth is 256 by default. Any value, except zero (0) is valid.
The f_timeout_seconds parameter specifies the number of seconds before the players opens a dialog box saying that the SWF animation is stuck.
This can be very useful if you have some heavy initialization which takes more resources than a few seconds (~15 seconds by default), and/or has a lot of recursivity (or just calls? to be tested...). You can then set large limits for the initialization to run fine, and then put some much lower limits afterward so as to ensure that the other scripts don't use too much resources.
