%% This work consists of the file luatex.def.
%%
%% Usage
%% =====
%%
%% It may be used by specifying the luatex option to any of the
%% supported packages, for example:
%%
%% \usepackage[luatex]{graphicx}
%%
%% * luatex determines the bounding box of the images itself
%%   Therefore the bounding box options should not be used.
%%   In this cases a warning is issued and viewport is used instead.
%% * Option "page" (graphicx) for selecting a page of a multipage
%%   PDF document.
%% * \pagecolor is supported. \nopagecolor disables the page color.
%% * Option "quiet" (graphicx/experimental): log messages are suppressed.
%% * Option "resolution" (graphicx/experimental): this sets
%%   \pdfvariable imageresolution, see luaTeX documentation.
%% * Option "print" (graphicx/experimental): specifies an alternate
%%   print image (bitmaps only), see PDF specification.
%% * luatex.def can be used under plain-TeX with miniltx support.
%%
%% "Experimental" means that these features can change or vanish
%% in later versions.
