 The fontloader backend can be selected by setting the value of
-``fontloader``. Other than the default, which selects the packaged
-``reference`` loader as shipped with Luaotfload, a file name accessible
-by kpathsea can be specified. Alternatively, the individual files that
-constitute the fontloader can be loaded directly. While less efficient,
-this greatly aids debugging since error messages will reference the
-actual line numbers of the source files and explanatory comments are
-not stripped. Currently, three distinct loading strategies are
-available: ``unpackaged`` will load the batch that is part of
-Luaotfload. These contain the identical source code that the reference
-fontloader has been compiled from. Another option, ``context`` will
-attempt to load the same files by their names in the Context format
-from the search path. Consequently this option allows to use the
-version of Context that comes with the TeX distribution. Distros tend
-to prefer the stable version (“current” in Context jargon) of those
-files so certain bugs encountered in the more bleeding edge Luaotfload
-can be avoided this way. A third option is to use ``context`` with a
-colon to specify a directory prefix where the *TEXMF* is located that
-the files should be loaded from, e. g. ``context:~/context/tex/texmf-context``.
-This can be used when referencing another distribution like the Context
-minimals that is installed under a different path not indexed by
