Minor English rephrasings

As I'm reading the Gradle tutorial (which is great, by the way), I'm running into a few language usage things that I think could be improved. For example, for some reason, "the above example", "the preceding example" and "the following example" all sound fine in American English, but "the below example" sounds really weird. No idea why. (And "the example preceding" and "the example following", while not strictly correct, sound archaic, so I left those alone.)  But I ran it by a couple of people, and they agreed, giggled, and shook their heads. English is odd, what can I say.
