+%% USAGE:
+%
+% \vpagelineref{<label>} expands to
+%
+% a) \ref{<label>}
+% -- if on same page as \linelabel{<label>}
+%
+% b) \LineWithPage{<label>} -- otherwise.
+%
+% \LineWithPage{<label>} expands -- by default -- to
+%
+% \pageref{<label>}.\ref{<label>}
+%
+% This can be customized by editing
+%
+% \renewcommand*{\LineWithPage}[1]{\pageref{#1}.\ref{#1}}
+%
+% in your document preamble, after vplref.sty has been loaded
+% (which may have happened through lineno.sty with option
+% `addpageno').

+%% IMPLEMENTATION:

+\ProvidesPackage{vplref}[\filedate\space v\fileversion]

+\AtBeginDocument{\RequirePackage{lineno,varioref}}

+%% <- Looks somewhat stupid, but varioref.sty has its merits
+%% as compared with the mechanism in ednotes.sty.
+ \vpageref[\ref{#1}][]{#1}%% The robust alternative.
+%% Here and with \LineWithPage, \lineref seems more appropriate
+%% than \ref, but it produces errors when labels have not been
+%% defined. This seems to be an incompatibility with lineno.sty.

+%% Customizable format for different page:
