I just know from [http://cheat.errtheblog.com/s/rcov](http://cheat.errtheblog.com/s/rcov) how to do spec’ing  
that excludes ruby libraries we have under vendor directory. So that I  
can use it happily ever after.

rake spec:rcov SHOW\_ONLY=“app”

I can explore rake tasks by typing `rake -T` under ruby project  
directory, but for this rake spec:rcov option, how would I know other  
options that are available besides SHOW\_ONLY ?

Thanks!
