- <para>To be able to use ticky-ticky profiling, you will need to
- have built the ticky RTS. (This should be described in

+ You don't need to build GHC, the libraries, or the RTS a special
+ way in order to use ticky-ticky profiling. You can decide on a
+ module-by-module basis which parts of a program have the
+ counters compiled in, using the
+ compile-time <option>-ticky</option> option. Those modules that
+ were not compiled with <option>-ticky</option> won't contribute
+ to the ticky-ticky profiling results, and that will normally
+ include all the pre-compiled packages that your program links
+ with.
