@defproc[(preheat-series!) void?]{

Save info about each series in @racket[series-folder] to the cache.

}

@defparam[current-plain-title title-plain non-empty-string? #:value "void"]{

Contains (or sets) the “plain” title (i.e., with no HTML markup) for the current article based on
analysis done by @racket[parse-and-cache-article!]. If the article did not specify a title,
a default title is supplied. If the article contained a @racket[note] that used the
@code{#:disposition} attribute, the disposition-mark may be included in the title.

This is a weird parameter, and at some point I will probably get rid of it and have
@racket[parse-and-cache-article!] supply it as an extra return value instead.

@margin-note{Note that this needs to be called @emph{after} @racket[parse-and-cache-article!] in
order to get an up-to-date value.}

}

@section{Retrieving cached data}

Some of this looks a little wacky, but it’s a case of putting a little extra complextity into the
back end to make things simple on the front end. These functions are most commonly used inside the
@emph{body} of a Pollen document (i.e., series pages).
