 By the way, the reason I included @racket[get-date] in this tutorial is to illustrate that not every function in a multi-output project necessarily needs to branch. (Static variables probably wouldn't either, though they could.) It produces a string, which is usable in either HTML or plain text. We just need to add branching to the tag functions that need context-specific behavior.

+I know that only the serious nerds are still with me, but let's review what's happening here.
 
 First, we use @filepath{template.pdf.p} rather than @filepath{template.pdf} for our template name. This is the @seclink["Null___p_extension_"] in use. Operating systems assume that files with a @racket[pdf] extension contain binary data, not text. The @racket[p] extension just shields the file from this assumption. It will simply be converted to @filepath{template.pdf} on render.
