@defproc[(series-pagetree) pagetree?])]
These are project-wide pagetrees: @racket[articles-pagetree] contains a pagenode for every Pollen
document contained in @racket[articles-path], and @racket[series-pagetree] contains a pagenode for
every Pollen document in @racket[series-path]. The pagenodes themselves point to the rendered
@tt{.html} targets of the source documents.
@section{Metas and @code{txexpr}s}
@defproc[(maybe-attr [key symbol?] [attrs txexpr-attrs?] [missing-expr any/c ""]) any/c]
Find the value of @racket[_key] in the supplied list of attributes, returning the value of
@racket[_missing-expr] if it’s not there.

@defproc[(here-output-path) path?]
Returns the path to the current output file, relative to @racket[current-project-root]. If no metas
are available, raises an error. This is like what you can get from the @tt{here} variable that Pollen
provides, except it is available outside templates.
@section{Metas and @code{txexpr}s}
@defproc[(maybe-attr [key symbol?] [attrs txexpr-attrs?] [missing-expr any/c ""]) any/c]
Find the value of @racket[_key] in the supplied list of attributes, returning the value of
@racket[_missing-expr] if it’s not there.
