30  * This tests the comet spell. My main motivation for writing this
31  * was to have a consistent test I could use for performance testing.
32  * But I also wanted to make sure that the results were close before and
33  * after the performance changes - make the spell use less cpu time
34  * but having drastically different results probably isn't a good thing
35  * either.
36  * To really be useful, everything needs to be compiled with profiling
37  * (-pg). This can be done like 'setenv CFLAGS -pg; ./configure;
38  * make clean; make'. The make clean is necessary because it won't
39  * recompile the objects based just on changes the the CFLAGS.
40  *
41  * Note that this test, even after performance changes are done, still
42  * isn't bad - it checks several things - map creation, spell casting,
43  * etc. It wouldn't be hard to use this as a template to test things
44  * like resistance code, etc.
