standard for internal-only tests?

[Jonathan Swartz]

There are certain tests in my distribution that I don't want end users  
to run. I want to run them during development, and I also want anyone  
else contributing to the distribution to run them. These are typically  
related to static analysis of the code, e.g. perl critic, perl tidy  
and pod checking - it makes no sense to risk having these fail for end  
users.

Is there a standard for signifying internal-only tests, and for make  
test to figure out when they should run?
