Well then you should be glad to hear that the current design does not have any 'built in' routines. It has some default checks, held in a seperate module that comes with the main verification package, but it is very easy to include checks from other places. Basically anything that returns true on sucess and false on failure can be used, via the 'custom' test declaration (which accepts coderef's and regex's.)
My code doesn't have bugs, it just develops random features.
