Should a directory path variable end with a trailing slash?

Question

When defining a path to a directory as a variable or constant, should it end with a trailing slash? What is the convention?

I know this is an old thread but I thought I'd share what I do. If possible, I'd normally allow for both and do something like this (if it was PHP):

$fullPath = rtrim($directory, '/') . '/filename.txt');

That way, if the directory is defined in a config file, it doesn't matter whether the next person to change it includes the trailing slash or not.
