-\subsection{Preparing the Font Loader}
-We treat the fontloader as a black box so behavior is consistent
-between formats.
-The wrapper file is \fileent{otfl-fonts.lua} which we imported from
-\href{http://standalone.contextgarden.net/current/context/experimental/tex/generic/context/luatex/}{\LUATEX-Plain}.
-It has roughly two purposes:
-
-\begin{enumerate}
-
-   \item insert the functionality required for fontloader; and
-
-   \item put it in place via the respective callbacks.
-
-\end{enumerate}
-
-How the first step is executed depends on the presence on the
-\emphasis{merged font loader code}.
-In \identifier{luaotfload} this is contained in the file
-\fileent{otfl-fonts-merged.lua}.
-If this file cannot be found,  the original libraries from \CONTEXT of
-which the merged code was composed are loaded instead.
-
-Hans provides two global tables to control the font loader:
-
-  \begin{itemize}
-    \item  \luafunction{generic_context}:
-           encapsulation mechanism, callback functions
-    \item  \luafunction{non generic_context}:
-           customized code insertion
-  \end{itemize}
-
-
-With \luafunction{non_generic_context} we can tailor the font loader
-insertion to our file naming habits (key \luafunction{load_before}).
-Additionally, \luafunction{skip_loading} can be unset to force loading
-of the original libraries as though the merged code was absent.
-Another key, \luafunction{load_after} is called at the time when the
-font loader is actually inserted.
-In combination with the option \luafunction{no_callbacks_yet} in
-\luafunction{generic_context}, we can insert our own,
-\identifier{luatexbase}-style callback handling here.
---doc]]--
-if not _G.    generic_context then _G.    generic_context = { } end
-if not _G.non_generic_context then _G.non_generic_context = { } end
-
-local     generic_context =    generic_context
-local non_generic_context =non_generic_context

-generic_context.no_callbacks_yet = true

-_G.non_generic_context = { luatex_fonts = {
-        load_before     = "otfl-fonts-merged.lua",
-        -- load_after      = nil, --- TODO, this is meant for callbacks
-        skip_loading    = true,
-}}

-The imported font loader will call \luafunction{callback.register} once
-while reading \fileent{font-def.lua}.
-This is unavoidable unless we modify the imported files, but harmless
-if we make it call a dummy instead.
---doc]]--
-
-local trapped_register = callback.register
-callback.register      = dummy_function

-By default, the fontloader requires a number of \emphasis{private
-attributes} for internal use.
-These must be kept consistent with the attribute handling methods as
-provided by \identifier{luatexbase}.
-Our strategy is to override the function that allocates new attributes
-before we initialize the font loader, making it a wrapper around
-\luafunction{luatexbase.new_attribute}.\footnote{%
-    Many thanks, again, to Hans Hagen for making this part
-    configurable!
-}
-The attribute identifiers are prefixed “\fileent{otfl@}” to
-avoid name clashes.
