-@deffn Command fast (@option{enable}|@option{disable})
-Default disabled.
-Set default behaviour of OpenOCD to be "fast and dangerous".
-
-At this writing, this only affects the defaults for two ARM7/ARM9 parameters:
-fast memory access, and DCC downloads.  Those parameters may still be
-individually overridden.
-
-The target specific "dangerous" optimisation tweaking options may come and go
-as more robust and user friendly ways are found to ensure maximum throughput
-and robustness with a minimum of configuration.
-
-Typically the "fast enable" is specified first on the command line:
-
-@example
-openocd -c "fast enable" -c "interface dummy" -f target/str710.cfg
-@end example
-@end deffn

 @deffn Command echo message
