Inside Twitter, './pants goal markdown' fails trying to load the page.mustache resource file.
But './pants goal builddict' works, and I know that uses resources.
I see that when TDesai fixed some resource-breakage, she edited this section.
And I see that this section mentions templates/builddictionary but not templates/markdown, so I'm hopeful; even though I'm vague about some (most?) parts of the pants->internal pants ritual.
