-Luaotfload is an adaptation of the ConTeXt font loading system for the Plain
-and LaTeX formats. It allows OpenType fonts to be loaded with font features
-accessible using an extended font request syntax while providing compatibility
-with XeTeX. By indexing metadata in a database it facilitates loading fonts by
-their proper names instead of file names.
-
-Luaotfload may be loaded in Plain LuaTeX with "\input luaotfload.sty" and in
-LuaLaTeX with "\usepackage{luaotfload}". LuaLaTeX users may be interested in
-the fontspec package which provides a high-level interface to the functionality
-provided by this package.
-
-Please see the documentation luaotfload.pdf for more information.
-
-This package is developed by the LuaLaTeX dev team on
-<http://github.com/lualatex/luaotfload>. Please report bugs to the issue

-Installation
--------------------------------------------------------------------------------
-
-Here are the recommended installation methods (preferred first).
-
-1. If you are using TeX Live 2008 or later, use 'tlmgr install luaotfload'.
- Alternatively, try your (TeX or Linux) distribution's package management
- system.
-
-2. a. Download luaotfload.tds.zip from CTAN.
- b. Unzip it at the root of one or your TDS trees.
- c. You may need to update some filename database after, see your TeX
- distribution's manual for details.
-
-3. a. Grab the sources from CTAN or github.
- b. Run 'make install DESTDIR=/path/to/texmf'.
- c. See 2c.
-
-4. Try to figure it out by looking at the Makefile and comments in the sources.
-
-Prerequisites
--------------------------------------------------------------------------------
-
-You need GNU make to use the Makefile. The executable may be called "gmake" on
-your system.
-
-Typesetting the documentation requires LuaTeX and GraphViz. The Docutils are
-needed to generate the manpage.

+\section{DESCRIPTION%
+ \label{description}%
+}
+
+The file \texttt{luaotfload.conf} contains configuration options for
+\emph{Luaotfload}, a font loading and font management component for LuaTeX.
+
+
+\section{EXAMPLE%
+ \label{example}%
+}
+
+A small Luaotfload configuration file with few customizations could
+look as follows:
+
+\begin{quote}
+\begin{alltt}
+[db]
+ formats = afm,ttf
+ compress = false
+
+[misc]
+ termwidth = 60
+
+[run]
+ log-level = 6
+\end{alltt}
+\end{quote}
+
+This will make Luaotfload ignore all font files except for PostScript
+binary fonts with a matching AFM file, and Truetype fonts. Also, an
+uncompressed index file will be dumped which is going to be much larger
+than the default gzip’ed index. The terminal width
+is truncated to 60 characters which influences the verbose output
+during indexing. Finally, the verbosity is increased greatly: each font
+file being processed will be printed to the stdout on a separate line,
+along with lots of other information.
+
+To observe the difference in behavior, save above snippet to
+\texttt{./luaotfload.conf} and update the font index:
+
+\begin{quote}
+\begin{alltt}
+luaotfload-tool --update --force
+\end{alltt}
+\end{quote}
+
+The current configuration can be written to disk using
+\textbf{luaotfload-tool}:
+
+\begin{quote}
+\begin{alltt}
+luaotfload-tool --dumpconf > luaotfload.conf
+\end{alltt}
+\end{quote}
+
+The result can itself be used as a configuration file.
+
+
+\section{SYNTAX%
+ \label{syntax}%
+}
+
+The configuration file syntax follows the common INI format. For a more
+detailed description please refer to the section “CONFIGURATION FILE”
+of \textbf{git-config}(1). A brief list of rules is given below:
+
+\begin{quote}
+\begin{itemize}
+\item Blank lines and lines starting with a semicolon (\texttt{;}) are ignored.
+
+\item A configuration file is partitioned into sections that are declared
+by specifying the section title in brackets on a separate line:
+
+\begin{quote}
+\begin{alltt}
+[some-section]
+... section content ...
+\end{alltt}
+\end{quote}
+
+\item Sections consist of one or more variable assignments of the form
+\texttt{variable-name = value} E. g.:
+
+\begin{quote}
+\begin{alltt}
+[foo]
+ bar = baz
+ quux = xyzzy
+ ...
+\end{alltt}
+\end{quote}
+
+\item Section and variable names may contain only uppercase and lowercase
+letters as well as dashes (\texttt{-}).
+\end{itemize}
+\end{quote}
+
+
+\section{VARIABLES%
+ \label{variables}%
+}
+
+Variables in belong into a configuration section and their values must
+be of a certain type. Some of them have further constraints. For
+example, the “color callback” must be a string of one of the values
+\texttt{post\_linebreak\_filter}, \texttt{pre\_linebreak\_filter}, or
+\texttt{pre\_output\_filter}, defined in the section \emph{run} of the
+configuration file.
+
+Currently, the configuration is organized into four sections:
+
+\begin{description}
+\item[{db}] \leavevmode
+Options relating to the font index.
+
+\item[{misc}] \leavevmode
+Options without a clearly defined category.
+
+\item[{paths}] \leavevmode
+Path and file name settings.
+
+\item[{run}] \leavevmode
+Options controlling runtime behavior of Luaotfload.
+
+\end{description}
+
+The list of valid variables, the sections they are part of and their
+type is given below. Types represent Lua types that the values must be
+convertible to; they are abbreviated as follows: \texttt{s} for the \emph{string}
+type, \texttt{n} for \emph{number}, \texttt{b} for \emph{boolean}. A value of \texttt{nil} means
+the variable is unset.
+
+
+\subsection{Section \texttt{db}%
+ \label{section-db}%
+}
+
+\setlength{\DUtablewidth}{\linewidth}
+\begin{longtable*}[c]{|p{0.249\DUtablewidth}|p{0.110\DUtablewidth}|p{0.331\DUtablewidth}|}
+\hline

+ \\
+\hline
+

+\texttt{false}
+ \\
+\hline
+

+

+ &
+\texttt{true}
+ \\
+\hline
+
+update-live
+ &
+b
+ &
+\texttt{true}
+ \\
+\hline
+\end{longtable*}
+
+The flag \texttt{compress} determines whether the font index (usually
+\texttt{luaotfload-names.lua{[}.gz{]}} will be stored in compressed forms.
+If unset it is equivalent of passing \texttt{--no-compress} to
+\textbf{luaotfload-tool}. Since the file is only created for convenience
+and has no effect on the runtime behavior of Luaotfload, the flag
+should remain set. Most editors come with zlib support anyways.
+
+The setting \texttt{designsize-dimen} applies when looking up fonts from
+families with design sizes. In Opentype, these are specified as
+“decipoints” where one decipoint equals ten DTP style “big points”.
+When indexing fonts these values are converted to \texttt{sp}. In order to
+treat the values as though they were specified in TeX points or Didot
+points, set \texttt{designsize-dimen} to \texttt{pt} or \texttt{dd}.
+
+The list of \texttt{formats} must be a comma separated sequence of strings
+containing one or more of these elements:
+
+\begin{itemize}
+\item \texttt{otf} (OpenType format),
+
+\item \texttt{ttf} and \texttt{ttc} (TrueType format),
+
+\item \texttt{afm} (Adobe Font Metrics),
+\end{itemize}
+
+It corresponds loosely to the \texttt{--formats} option to
+\textbf{luaotfload-tool}. Invalid or duplicate members are ignored; if the
+list does not contain any useful identifiers, the default list
+\texttt{\textquotedbl{}otf,ttf,ttc\textquotedbl{}} will be used.
+
+The variable \texttt{max-fonts} determines after processing how many font
+files the font scanner will terminate the search. This is useful for
+debugging issues with the font index and has the same effect as the
+option \texttt{--max-fonts} to \textbf{luaotfload-tools}.
+
+The \texttt{scan-local} flag, if set, will incorporate the current working
+directory as a font search location. NB: This will potentially slow
+down document processing because a font index with local fonts will not
+be saved to disk, so these fonts will have to be re-indexed whenever
+the document is built.
+
+The \texttt{skip-read} flag is only useful for debugging: It makes
+Luaotfload skip reading fonts. The font information for rebuilding the
+index is taken from the presently existing one.
+
+Unsetting the \texttt{strip} flag prevents Luaotfload from removing data
+from the index that is only useful when processing font files. NB: this
+can increase the size of the index files significantly and has no
+effect on the runtime behavior.
+
+If \texttt{update-live} is set, Luaotfload will reload the database if it
+cannot find a requested font. Those who prefer to update manually using
+\textbf{luaotfload-tool} should unset this flag. This option does not affect
+rebuilds due to version mismatch.
+
+
+\subsection{Section \texttt{default-features}%
+ \label{section-default-features}%
+}
+
+By default Luaotfload enables \texttt{node} mode and picks the default font
+features that are prescribed in the OpenType standard. This behavior
+may be overridden in the \texttt{default-features} section. Global defaults
+that will be applied for all scripts can be set via the \texttt{global}
+option, others by the script they are to be applied to. For example,
+a setting of
+
+\begin{quote}
+\begin{alltt}
+[default-features]
+ global = mode=base,color=0000FF
+ dflt = smcp,onum
+\end{alltt}
+\end{quote}
+
+would force \emph{base} mode, tint all fonts blue and activate small
+capitals and text figures globally. Features are specified as a comma
+separated list of variables or variable-value pairs. Variables without
+an explicit value are set to \texttt{true}.
+
+
+\subsection{Section \texttt{misc}%
+ \label{section-misc}%
+}
+
+\setlength{\DUtablewidth}{\linewidth}
+\begin{longtable*}[c]{|p{0.191\DUtablewidth}|p{0.110\DUtablewidth}|p{0.307\DUtablewidth}|}

+\texttt{nil}
+ \\
+\hline
+
+version
+ &
+s
+ &
+<Luaotfload version>
+ \\
+\hline
+\end{longtable*}
+
+With \texttt{statistics} enabled, extra statistics will be collected during
+index creation and appended to the index file. It may then be queried
+at the Lua end or inspected by reading the file itself.
+
+The value of \texttt{termwidth}, if set, overrides the value retrieved by
+querying the properties of the terminal in which Luatex runs. This is
+useful if the engine runs with \texttt{shell\_escape} disabled and the actual
+terminal dimensions cannot be retrieved.
+
+The value of \texttt{version} is derived from the version string hard-coded
+in the Luaotfload source. Override at your own risk.
+
+
+\subsection{Section \texttt{paths}%
+ \label{section-paths}%
+}
+
+\setlength{\DUtablewidth}{\linewidth}
+\begin{longtable*}[c]{|p{0.226\DUtablewidth}|p{0.110\DUtablewidth}|p{0.435\DUtablewidth}|}

+\texttt{\textquotedbl{}luaotfload-lookup-cache.lua\textquotedbl{}}
+ \\
+\hline
+\end{longtable*}
+
+The paths \texttt{cache-dir} and \texttt{names-dir} determine the subdirectory
+inside the Luaotfload subtree of the \texttt{luatex-cache} directory where
+the font cache and the font index will be stored, respectively.
+
+Inside the index directory, the names of the index file and the font
+lookup cache will be derived from the respective values of
+\texttt{index-file} and \texttt{lookups-file}. This is the filename base for the
+bytecode compiled version as well as -- for the index -- the gzipped
+version.
+
+
+\subsection{Section \texttt{run}%
+ \label{section-run}%

+
+\setlength{\DUtablewidth}{\linewidth}

+\end{longtable*}
+
+Unqualified font lookups are treated with the flexible “anonymous”
+mechanism. This involves a chain of lookups applied successively until
+the first one yields a match. By default, the lookup will first search
+for TFM fonts using the Kpathsea library. If this wasn’t successful, an
+attempt is made at interpreting the request as an absolute path (like
+the \texttt{{[}/path/to/font/foo.ttf{]}} syntax) or a file name
+(\texttt{file:foo.ttf}). Finally, the request is interpreted as a font name
+and retrieved from the index (\texttt{name:Foo Regular}). This behavior can
+be configured by specifying a list as the value to \texttt{anon-sequence}.
+Available items are \texttt{tex}, \texttt{path}, \texttt{name} -- representing the
+lookups described above, respectively --, and \texttt{file} for searching a
+filename but not an absolute path. Also, \texttt{my} lookups are valid
+values but they should only be used from within TeX documents, because
+there is no means of customizing a \texttt{my} lookups on the command line.
+
+The \texttt{color-callback} option determines the stage at which fonts that
+defined with a \texttt{color=xxyyzz} feature will be colorized. By default
+this happens in a \texttt{post\_linebreak\_filter} but alternatively the
+\texttt{pre\_linebreak\_filter} or \texttt{pre\_output\_filter} may be chosen, which
+is faster but might produce inconsistent output. The
+\texttt{pre\_output\_filter} used to be the default in the 1.x series of
+Luaotfload, whilst later versions up to and including 2.5 hooked into
+the \texttt{pre\_linebreak\_filter} which naturally didn’t affect any glyphs
+inserting during hyphenation. Both are kept around as options to
+restore the previous behavior if necessary.
+
+The \texttt{definer} allows for switching the \texttt{define\_font} callback.
+Apart from the default \texttt{patch} one may also choose the \texttt{generic}
+one that comes with the vanilla fontloader. Beware that this might
+break tools like Fontspec that rely on the \texttt{patch\_font} callback
+provided by Luaotfload to perform important corrections on font data.
+
+The fontloader backend can be selected by setting the value of
+\texttt{fontloader}. The most important choices are \texttt{default}, which will
+load the dedicated Luaotfload fontloader, and \texttt{reference}, the
+upstream package as shipped with Luaotfload. Other than those, a file
+name accessible via 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: \texttt{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, \texttt{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 \texttt{context} with a colon to specify a directory prefix where
+the \emph{TEXMF} is located that the files should be loaded from, e. g.
+\texttt{context:\textasciitilde{}/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 kpathsea.
+
+The value of \texttt{log-level} sets the default verbosity of messages
+printed by Luaotfload. Only messages defined with a verbosity of less
+than or equal to the supplied value will be output on the terminal.
+At a log level of five Luaotfload can be very noisy. Also, printing too
+many messages will slow down the interpreter due to line buffering
+being disabled (see \textbf{setbuf}(3)).
+
+The \texttt{resolver} setting allows choosing the font name resolution
+function: With the default value \texttt{cached} Luaotfload saves the result
+of a successful font name request to a cache file to speed up
+subsequent lookups. The alternative, \texttt{normal} circumvents the cache
+and resolves every request individually. (Since to the restructuring of
+the font name index in Luaotfload 2.4 the performance difference
+between the cached and uncached lookups should be marginal.)
+
+
+\section{FILES%
+ \label{files}%
+}
+
+Luaotfload only processes the first configuration file it encounters at
+one of the search locations. The file name may be either
+\texttt{luaotfload.conf} or \texttt{luaotfloadrc}, except for the dotfile in the
+user’s home directory which is expected at \texttt{\textasciitilde{}/.luaotfloadrc}.
+
+Configuration files are located following a series of steps. The search
+terminates as soon as a suitable file is encountered. The sequence of
+locations that Luaotfload looks at is
+
+\begin{enumerate}
+\renewcommand{\labelenumi}{\roman{enumi}.}
+\item The current working directory of the LuaTeX process.
+
+\item The subdirectory \texttt{luaotfload/} inside the XDG configuration
+tree, e. g. \texttt{/home/oenothea/config/luaotfload/}.
+
+\item The dotfile.
+
+\item The \emph{TEXMF} (using kpathsea).

+\beginsection {New in version 2.9 (by Ulrike Fischer)}
+
+On the one side there is not very much new in this version: The native components of \identifier{Luaotfload} are nearly unchanged. A few bugs have been corrected, the various files lists which loads the components of the font loader have been cleaned up.
+
+On the other side there is a lot new:
+
+\begindescriptions
+
+ \beginaltitem {Fontloader} The fontloader files imported from \CONTEXT\ have been updated to the current version.
+ This was necessary to make \identifier{Luaotfload} compatible with the comimg \LUATEX 1.08. Compared to the previous version from february 2017 quite a number of things have changed. Most importantly the handling of arabic fonts has greatly improved. But this also means that changes in the output are possible.
+ \endaltitem
+
+ \beginaltitem {Lualibs} The update of the fontloader files also required an update of the \identifier{Lualibs} package. This \identifier{Luaotfload} versions needs version 2.6 of \identifier{Lualibs}.
+ \endaltitem
+
+ \beginaltitem {Maintenance} As the current maintainer wasn't available and it was urgent to get a \identifier{Luaotfload} compatible with \LUATEX 1.08 maintenance has been transfered to Ulrike Fischer and Marcel Krüger. The package is currently maintained and developed at \hyperlink{https://github.com/u-fischer/luaotfload.git}. Issues should be reported there.
+ \endaltitem
+
+ \beginaltitem {Documentation}
+ The core of documentation is nearly unchanged. I added this introduction. I recreated with the help of @marmot the graphic. I updated the file lists. I imported as appendix pdf versions of the two man files which are part of the \identifier{Luaotfload} documentation.

+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+\beginsection {Introduction}
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+
+Font management and installation has always been painful with \TEX. A
+lot of files are needed for one font (\abbrev{tfm}, \abbrev{pfb},
+\abbrev{map}, \abbrev{fd}, \abbrev{vf}), and due to the 8-Bit encoding
+each font is limited to 256 characters.
+
+But the font world has evolved since the original \TEX, and new
+typographic systems have appeared, most notably the so called
+\emphasis{smart font} technologies like \OpenType fonts (\abbrev{otf}).
+
+These fonts can contain many more characters than \TEX fonts, as well
+as additional functionality like ligatures, old-style numbers, small
+capitals, etc., and support more complex writing systems like Arabic
+and Indic\footnote{%
+ Unfortunately, \identifier{luaotfload} doesn‘t support many Indic
+ scripts right now.
+ Assistance in implementing the prerequisites is greatly
+ appreciated.
+}
+scripts.
+
+\OpenType fonts are widely deployed and available for all modern
+operating systems.
+
+As of 2013 they have become the de facto standard for advanced text
+layout.
+
+However, until recently the only way to use them directly in the \TEX
+world was with the \XETEX engine.
+
+Unlike \XETEX, \LUATEX has no built-in support for \OpenType or
+technologies other than the original \TEX fonts.
+
+Instead, it provides hooks for executing \LUA code during the \TEX run
+that allow implementing extensions for loading fonts and manipulating
+how input text is processed without modifying the underlying engine.
+
+This is where \identifier{luaotfload} comes into play:
+Based on code from \CONTEXT, it extends \LUATEX with functionality necessary
+for handling \OpenType fonts.
+
+Additionally, it provides means for accessing fonts known to the operating
+system conveniently by indexing the metadata.
+
+\endsection
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+\beginsection {Thanks}
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+
+\identifier{Luaotfload} is part of \LUALATEX, the community-driven
+project to provide a foundation for using the \LATEX format with the
+full capabilites of the \LUATEX engine.
+%
+As such, the distinction between end users, contributors, and project
+maintainers is intentionally kept less strict, lest we unduly
+personalize the common effort.
+
+Nevertheless, the current maintainers would like to express their
+gratitude to Khaled Hosny, Akira Kakuto, Hironori Kitagawa and Dohyun
+Kim.
+%
+Their contributions -- be it patches, advice, or systematic
+testing -- made the switch from version 1.x to 2.2 possible.
+%
+Also, Hans Hagen, the author of the font loader, made porting the
+code to \LATEX a breeze due to the extra effort he invested into
+isolating it from the rest of \CONTEXT, not to mention his assistance
+in the task and willingness to respond to our suggestions.
+

+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+\beginsection {Loading Fonts}
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+
+\identifier{luaotfload} supports an extended font request syntax:
+
+\beginnarrower
+ \nonproportional{\string\font\string\foo\space= \string{}%
+ \meta{prefix}\nonproportional{:}%
+ \meta{font name}\nonproportional{:}%
+ \meta{font features}\nonproportional{\string}}%
+ \meta{\TEX font features}
+\endnarrower
+
+\noindent
+The curly brackets are optional and escape the spaces in the enclosed
+font name.
+%
+Alternatively, double quotes serve the same purpose.
+%
+A selection of individual parts of the syntax are discussed below;
+for a more formal description see figure \ref{font-syntax}.
+
+\beginsyntaxfloat
+ {font-syntax}
+ {Font request syntax.
+ Braces or double quotes around the
+ \emphasis{specification} rule will
+ preserve whitespace in file names.
+ In addition to the font style modifiers
+ (\emphasis{slash-notation}) given above, there
+ are others that are recognized but will be silently
+ ignored: \nonproportional{aat},
+ \nonproportional{icu}, and
+ \nonproportional{gr}.
+ The special terminals are:
+ \smallcaps {feature\textunderscore id} for a valid font
+ feature name and
+ \smallcaps {feature\textunderscore value} for the corresponding
+ value.
+ \smallcaps {tfmname} is the name of a \abbrev{tfm} file.
+ \smallcaps {digit} again refers to bytes 48--57, and
+ \smallcaps {all\textunderscore characters} to all byte values.
+ \smallcaps {csname} and \smallcaps {dimension} are the \TEX concepts.}

+ A \inlinecode {kpse} lookup is restricted to files that can be found by
+ \identifier{kpathsea} and will not attempt to locate system fonts.
+ %
+ This behavior can be of value when an extra degree of encapsulation is
+ needed, for instance when supplying a customized tex distribution.
+
+ The \inlinecode {my} lookup takes this a step further: it lets you define
+ a custom resolver function and hook it into the \luaident{resolve_font}
+ callback.
+ %
+ This ensures full control over how a file is located.
+ %
+ For a working example see the
+ \hyperlink [test repo]{https://bitbucket.org/phg/lua-la-tex-tests/src/5f6a535d/pln-lookup-callback-1.tex}.
+}
+%
+It determines whether the font loader should interpret the request as
+a \emphasis{file name} or
+ \emphasis{font name}, respectively,
+which again influences how it will attempt to locate the font.
+%
+Examples for font names are
+ “Latin Modern Italic”,
+ “GFS Bodoni Rg”, and
+ “PT Serif Caption”
+-- they are the human readable identifiers
+usually listed in drop-down menus and the like.\footnote{%
+ Font names may appear like a great choice at first because they
+ offer seemingly more intuitive identifiers in comparison to arguably
+ cryptic file names:
+ %
+ “PT Sans Bold” is a lot more descriptive than \fileent{PTS75F.ttf}.
+ On the other hand, font names are quite arbitrary and there is no
+ universal method to determine their meaning.
+ %
+ While \identifier{luaotfload} provides fairly sophisticated heuristic
+ to figure out a matching font style, weight, and optical size, it
+ cannot be relied upon to work satisfactorily for all font files.
+ %
+ For an in-depth analysis of the situation and how broken font names
+ are, please refer to
+ \hyperlink [this post]{http://www.ntg.nl/pipermail/ntg-context/2013/073889.html}
+ by Hans Hagen, the author of the font loader.
+ %
+ If in doubt, use filenames.
+ %
+ \fileent{luaotfload-tool} can perform the matching for you with the
+ option \inlinecode {--find=<name>}, and you can use the file name it returns
+ in your font definition.
+}
+%
+In order for fonts installed both in system locations and in your
+\fileent{texmf} to be accessible by font name, \identifier{luaotfload} must
+first collect the metadata included in the files.
+%
+Please refer to section~\ref{sec:fontdb} below for instructions on how to
+create the database.
+
+File names are whatever your file system allows them to be, except
+that that they may not contain the characters
+ \inlinecode {(},
+ \inlinecode {:}, and
+ \inlinecode {/}.
+%
+As is obvious from the last exception, the \inlinecode {file:} lookup will
+not process paths to the font location -- only those
+files found when generating the database are addressable this way.
+%
+Continue below in the \XETEX section if you need to load your fonts
+by path.
+%
+The file names corresponding to the example font names above are
+ \fileent{lmroman12-italic.otf},
+ \fileent{GFSBodoni.otf}, and
+ \fileent{PTZ56F.ttf}.
+
+\endsubsection
+
+\beginsubsection {Bracketed Lookups}
+\label{sec:bracket}
+Bracketed lookups allow for arbitrary character content to be used in a
+definition.
+%
+A simple bracketed request looks follows the scheme
+
+\beginnarrower
+ \nonproportional{\string\font\string\fontname\space = [}%
+ \meta{/path/to/file}%
+ \nonproportional{]}
+\endnarrower
+
+\noindent
+Inside the square brackets, every character except for a closing bracket is
+permitted, allowing for arbitrary paths to a font file -- including Windows
+style paths with UNC or drive letter prepended -- to be specified.
+%
+The \identifier{Luaotfload} syntax differs from \XETEX in that the subfont
+selector goes \emphasis{after} the closing bracket:
+
+\beginnarrower
+ \nonproportional{\string\font\string\fontname\space = [}%
+ \meta{/path/to/file}%
+ \nonproportional{]}
+ \nonproportional{(}n\nonproportional{)}
+\endnarrower
+
+Naturally, path-less file names are equally valid and processed the
+same way as an ordinary \inlinecode {file:} lookup.
+
+\beginsubsection {Compatibility}
+
+In addition to the regular prefixed requests, \identifier{luaotfload}
+accepts loading fonts the \XETEX way.
+%
+There are again two modes: bracketed and unbracketed.
+For the bracketed variety, see above, \ref{sec:bracket}.
+
+Unbracketed (or, for lack of a better word: \emphasis{anonymous})
+font requests resemble the conventional \TEX syntax.
+
+\beginnarrower
+ \nonproportional{\string\font\string\fontname\space= }%
+ \meta{font name}
+ \dots
+\endnarrower
+\endsubsection
+
+However, they have a broader spectrum of possible interpretations:
+before anything else, \identifier{luaotfload} attempts to load a
+traditional \TEX Font Metric (\abbrev{tfm} or \abbrev{ofm}).
+%
+If this fails, it performs a \inlinecode {path:} lookup, which itself will
+fall back to a \inlinecode {file:} lookup.
+%
+Lastly, if none of the above succeeded, attempt to resolve the request as a
+\inlinecode {name:} lookup by searching the font index for \meta{font name}.
+%
+The behavior of this “anonymous” lookup is configurable, see the configuation
+manpage for details.
+
+Furthermore, \identifier{luaotfload} supports the slashed (shorthand)
+font style notation from \XETEX.
+
+\beginnarrower
+ \nonproportional{\string\font\string\fontname\space= }%
+ \meta{font name}%
+ \nonproportional{/}%
+ \meta{modifier}
+ \dots
+\endnarrower
+
+\noindent
+Currently, four style modifiers are supported:
+ \inlinecode {I} for italic shape,
+ \inlinecode {B} for bold weight,
+ \inlinecode {BI} or \inlinecode {IB} for the combination of both.
+%
+Other “slashed” modifiers are too specific to the \XETEX engine and
+have no meaning in \LUATEX.
+
+\endsubsection
+
+\beginsubsection{Examples}
+
+\beginsubsubsection{Loading by File Name}
+
+For example, conventional \TeX\ font can be loaded with a
+\inlinecode {file:} request like so:
+
+\beginlisting
+ \font \lmromanten = {file:ec-lmr10} at 10pt
+\endlisting
+
+The \OpenType version of Janusz Nowacki’s font \emphasis{Antykwa
+Półtawskiego}\footnote{%
+ \hyperlink {http://jmn.pl/antykwa-poltawskiego/}, also available in
+ in \TEX Live.
+}
+in its condensed variant can be loaded as follows:
+
+\beginlisting
+ \font \apcregular = file:antpoltltcond-regular.otf at 42pt
+\endlisting
+
+The next example shows how to load the \emphasis{Porson} font digitized by
+the Greek Font Society using \XETEX-style syntax and an absolute path from a
+non-standard directory:
+
+\beginlisting
+ \font \gfsporson = "[/tmp/GFSPorson.otf]" at 12pt
+\endlisting
+
+\identifier{TrueType} collection files (the extension is usually
+\inlinecode{.ttc}) contain more than a single font. In order to refer to these
+subfonts, the respective index may be added in parentheses after the file
+name.\footnote{%
+ Incidentally, this syntactical detail also prevents one from loading files
+ that end in balanced parentheses.
+}
+
+\beginlisting
+ \font \cambriamain = "file:cambria.ttc(0)" at 10pt
+ \font \cambriamath = "file:cambria.ttc(1)" at 10pt
+\endlisting
+
+and likewise, requesting subfont inside a TTC container by path:
+
+\beginlisting
+ \font \asanamain = "[/home/typesetter/.fonts/math/asana.ttc](0):mode=node;+tlig" at 10pt
+ \font \asanamath = "[/home/typesetter/.fonts/math/asana.ttc](1):mode=base" at 10pt
+\endlisting
+
+\endsubsubsection
+
+\beginsubsubsection{Loading by Font Name}
+
+The \inlinecode {name:} lookup does not depend on cryptic filenames:
+
+\beginlisting
+ \font \pagellaregular = {name:TeX Gyre Pagella} at 9pt
+\endlisting
+
+A bit more specific but essentially the same lookup would be:
+
+\beginlisting
+ \font \pagellaregular = {name:TeX Gyre Pagella Regular} at 9pt
+\endlisting
+
+\noindent
+Which fits nicely with the whole set:
+
+\beginlisting
+ \font\pagellaregular = {name:TeX Gyre Pagella Regular} at 9pt
+ \font\pagellaitalic = {name:TeX Gyre Pagella Italic} at 9pt
+ \font\pagellabold = {name:TeX Gyre Pagella Bold} at 9pt
+ \font\pagellabolditalic = {name:TeX Gyre Pagella Bolditalic} at 9pt
+
+ {\pagellaregular foo bar baz\endgraf}
+ {\pagellaitalic foo bar baz\endgraf}
+ {\pagellabold foo bar baz\endgraf}
+ {\pagellabolditalic foo bar baz\endgraf}
+
+ ...
+\endlisting
+
+\endsubsubsection
+
+\beginsubsubsection{Modifiers}
+
+If the entire \emphasis{Iwona} family\footnote{%
+ \hyperlink {http://jmn.pl/kurier-i-iwona/},
+ also in \TEX Live.
+}
+is installed in some location accessible by \identifier{luaotfload},
+the regular shape can be loaded as follows:
+
+\beginlisting
+ \font \iwona = Iwona at 20pt
+\endlisting
+
+\noindent
+To load the most common of the other styles, the slash notation can
+be employed as shorthand:
+
+\beginlisting
+ \font \iwonaitalic = Iwona/I at 20pt
+ \font \iwonabold = Iwona/B at 20pt
+ \font \iwonabolditalic = Iwona/BI at 20pt
+\endlisting
+
+\noindent
+which is equivalent to these full names:
+
+\beginlisting
+ \font \iwonaitalic = "Iwona Italic" at 20pt
+ \font \iwonabold = "Iwona Bold" at 20pt
+ \font \iwonabolditalic = "Iwona BoldItalic" at 20pt
+\endlisting
+

+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+\beginsection {Font features}
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+
+\emphasis{Font features} are the second to last component in the
+general scheme for font requests:
+
+\beginnarrower
+ \nonproportional{\string\font\string\foo\space= "}%
+ \meta{prefix}%
+ \nonproportional{:}%
+ \meta{font name}%
+ \nonproportional{:}%
+ \meta{font features}%
+ \meta{\TEX font features}%
+ \nonproportional{"}
+\endnarrower
+
+\noindent
+If style modifiers are present (\XETEX style), they must precede
+\meta{font features}.
+
+The element \meta{font features} is a semicolon-separated list of feature
+tags\footnote{%
+ Cf. \hyperlink {http://www.microsoft.com/typography/otspec/featurelist.htm}.
+}
+and font options.
+%
+Prepending a font feature with a \inlinecode{+} (plus sign) enables it,
+whereas a \inlinecode{-} (minus) disables it. For instance, the request
+
+\beginlisting
+ \font \test = LatinModernRoman:+clig;-kern
+\endlisting
+
+\noindent activates contextual ligatures (\inlinecode{clig}) and
+disables kerning (\inlinecode{kern}).
+%
+Alternatively the options \inlinecode{true} or \inlinecode{false} can
+be passed to the feature in a key/value expression.
+%
+The following request has the same meaning as the last one:
+
+\beginlisting
+ \font \test = LatinModernRoman:clig=true;kern=false
+\endlisting
+
+\noindent
+Furthermore, this second syntax is required should a font feature
+accept other options besides a true/false switch.
+%
+For example, \emphasis{stylistic alternates} (\inlinecode{salt}) are
+variants of given glyphs.
+%
+They can be selected either explicitly by supplying the variant
+index (starting from one), or randomly by setting the value to,
+obviously, \inlinecode{random}.
+
+%% TODO verify that this actually works with a font that supports
+%% the salt/random feature!\fi
+\beginlisting
+ \font \librmsaltfirst = LatinModernRoman:salt=1
+\endlisting
+
+\beginsubsection {Basic font features}
+
+\begindescriptions
+
+ \beginaltitem {mode}
+ \identifier{luaotfload} has two \OpenType processing
+ \emphasis{modes}:
+ \identifier{base} and \identifier{node}.
+
+ \identifier{base} mode works by mapping \OpenType
+ features to traditional \TEX ligature and kerning mechanisms.
+ %
+ Supporting only non-contextual substitutions and kerning
+ pairs, it is the slightly faster, albeit somewhat limited, variant.
+ %
+ \identifier{node} mode works by processing \TeX’s internal
+ node list directly at the \LUA end and supports
+ a wider range of \OpenType features.
+ %
+ The downside is that the intricate operations required for
+ \identifier{node} mode may slow down typesetting especially
+ with complex fonts and it does not work in math mode.
+
+ By default \identifier{luaotfload} is in \identifier{node}
+ mode, and \identifier{base} mode has to be requested where needed,
+ e.~g. for math fonts.
+ \endaltitem
+
+ \beginaltitem {script} \label{script-tag}
+ An \OpenType script tag;\footnote{%
+ See \hyperlink {http://www.microsoft.com/typography/otspec/scripttags.htm}
+ for a list of valid values.
+ %
+ For scripts derived from the Latin alphabet the value
+ \inlinecode{latn} is good choice.
+ }
+ the default value is \inlinecode{dflt}.
+ %
+ Some fonts, including very popular ones by foundries like Adobe,
+ do not assign features to the \inlinecode{dflt} script, in
+ which case the script needs to be set explicitly.
+ \endaltitem
+
+ \beginaltitem {language}
+ An \OpenType language system identifier,\footnote{%
+ Cf. \hyperlink {http://www.microsoft.com/typography/otspec/languagetags.htm}.
+ }
+ defaulting to \inlinecode{dflt}.
+ \endaltitem
+
+ \beginaltitem {color}
+ A font color, defined as a triplet of two-digit hexadecimal
+ \abbrev{rgb} values, with an optional fourth value for
+ transparency
+ (where \inlinecode{00} is completely transparent and
+ \inlinecode{FF} is opaque).
+
+ For example, in order to set text in semitransparent red:
+
+ \beginlisting
+ \font \test = "Latin Modern Roman:color=FF0000BB"
+ \endlisting
+ \endaltitem
+
+ \beginaltitem {kernfactor \& letterspace}
+ Define a font with letterspacing (tracking) enabled.
+ %
+ In \identifier{luaotfload}, letterspacing is implemented by
+ inserting additional kerning between glyphs.
+
+ This approach is derived from and still quite similar to the
+ \emphasis{character kerning} (\texmacro{setcharacterkerning} /
+ \texmacro{definecharacterkerning} \& al.) functionality of
+ Context, see the file \fileent{typo-krn.lua} there.
+ %
+ The main difference is that \identifier{luaotfload} does not
+ use \LUATEX attributes to assign letterspacing to regions,
+ but defines virtual letterspaced versions of a font.
+
+ The option \identifier{kernfactor} accepts a numeric value that
+ determines the letterspacing factor to be applied to the font
+ size.
+ %
+ E.~g. a kern factor of $0.42$ applied to a $10$ pt font
+ results in $4.2$ pt of additional kerning applied to each
+ pair of glyphs.
+ %
+ Ligatures are split into their component glyphs unless
+ explicitly ignored (see below).
+
+ For compatibility with \XETEX an alternative
+ \identifier{letterspace} option is supplied that interprets the
+ supplied value as a \emphasis{percentage} of the font size but
+ is otherwise identical to \identifier{kernfactor}.
+ %
+ Consequently, both definitions in below snippet yield the same
+ letterspacing width:
+
+ \beginlisting
+ \font \iwonakernedA = "file:Iwona-Regular.otf:kernfactor=0.125"
+ \font \iwonakernedB = "file:Iwona-Regular.otf:letterspace=12.5"
+ \endlisting
+
+ Specific pairs of letters and ligatures may be exempt from
+ letterspacing by defining the \LUA functions
+ \luaident{keeptogether} and \luaident{keepligature},
+ respectively, inside the namespace \inlinecode {luaotfload.letterspace}.
+ %
+ Both functions are called whenever the letterspacing callback
+ encounters an appropriate node or set of nodes.
+ %
+ If they return a true-ish value, no extra kern is inserted at
+ the current position.
+ %
+ \luaident{keeptogether} receives a pair of consecutive
+ glyph nodes in order of their appearance in the node list.
+ %
+ \luaident{keepligature} receives a single node which can be
+ analyzed into components.
+ %
+ (For details refer to the \emphasis{glyph nodes} section in the
+ \LUATEX reference manual.)
+ %
+ The implementation of both functions is left entirely to the
+ user.
+ \endaltitem

+ \directlua{inspect(fonts.protrusions.setups.default)
+ inspect(fonts.expansions.setups.default)}
+ \stopbuffer
+\fi
+
+ \beginaltitem {protrusion \& expansion}
+ These keys control microtypographic features of the font,
+ namely \emphasis{character protrusion} and \emphasis{font
+ expansion}.
+ %
+ Their arguments are names of \LUA tables that contain
+ values for the respective features.\footnote{%
+ For examples of the table layout please refer to the
+ section of the file \fileent{luaotfload-fonts-ext.lua} where the

+ %
+ For both, only the set \identifier{default} is predefined.

+ For example, to define a font with the default
+ protrusion vector applied\footnote{%

+ \inlinecode {pdfadjustspacing=2}
+ to activate protrusion and expansion, respectively.

+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+\beginsection {Combining fonts}
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+
+Version 2.7 and later support combining characters from multiple fonts into a
+single virtualized one. This requires that the affected fonts be loaded in
+advance as well as a special \emphasis{request syntax}. Furthermore, this
+allows to define \emphasis{fallback fonts} to supplement fonts that may lack
+certain required glyphs.
+
+Combinations are created by defining a font using the \luaident{combo:} prefix.
+
+\beginsubsection {Fallbacks}
+
+For example, the \identifier{Latin Modern} family of fonts does, as indicated
+in the name, not provide Cyrillic glyphs. If Latin script dominates in the copy
+with interspersed Cyrillic, a fallback can be created from a similiar looking
+font like \identifier{Computer Modern Unicode}, taking advantage of the fact
+that it too derives from Knuth’s original \identifier{Computer Modern} series:
+
+\beginlisting
+ \input luaotfload.sty
+ \font \lm = file:lmroman10-regular.otf:mode=base
+ \font \cmu = file:cmunrm.otf:mode=base
+ \font \lmu = "combo: 1->\fontid\lm; 2->\fontid\cmu,fallback"
+ \lmu Eh bien, mon prince. Gênes et Lueques ne sont plus que des
+ apanages, des поместья, de la famille Buonaparte.
+ \bye
+\endlisting
+
+As simple as this may look on the first glance, this approach is entirely
+inappropriate if more than a couple letters are required from a different font.
+Because the combination pulls nothing except the glyph data, all of the
+important other information that constitute a proper font -- kerning, styles,
+features, and suchlike -- will be missing.
+
+\endsubsection %% Fallbacks
+
+\beginsubsection {Combinations}
+
+Generalizing the idea of a \emphasis{fallback font}, it is also possible to
+pick definite sets of glyphs from multiple fonts. On a bad day, for instance,
+it may be the sanest choice to start out with \identifier{EB Garamond} italics,
+typeset all decimal digits in the bold italics of \identifier{GNU Freefont},
+and tone down the punctuation with extra thin glyphs from \identifier{Source
+Sans}:
+
+\beginlisting
+ \def \feats {-tlig;-liga;mode=base;-kern}
+ \def \fileone {EBGaramond12-Italic.otf}
+ \def \filetwo {FreeMonoBoldOblique.otf}
+ \def \filethree {SourceSansPro-ExtraLight.otf}
+
+ \input luaotfload.sty
+
+ \font \one = file:\fileone :\feats
+ \font \two = file:\filetwo :\feats
+ \font \three = file:\filethree:\feats
+
+ \font \onetwothree = "combo: 1 -> \fontid\one;
+ 2 -> \fontid\two, 0x30-0x39;
+ 3 -> \fontid\three, 0x21*0x3f; "
+
+ {\onetwothree \TeX—0123456789—?!}
+ \bye
+\endlisting
+
+\noindent Despite the atrocious result, the example demonstrates well the
+syntax that is used to specify ranges and fonts. Fonts are being referred to by
+their internal index which can be obtained by passing the font command into the
+\texmacro{fontid} macro, e. g. \inlinecode{\fontid\one}, after a font has been
+defined. The first component of the combination is the base font which will be
+extended by the others. It is specified by the index alone.
+
+All further fonts require either the literal \inlinecode{fallback} or a list of
+codepoint definitions to be appended after a comma. The elements of this list
+again denote either single codepoints like \inlinecode{0x21} (referring to the
+exclamation point character) or ranges of codepoints (\inlinecode{0x30-0x39}).
+Elements are separated by the \identifier{ASCII} asterisk character
+(\inlinecode{*}). The characters referenced in the list will be imported from
+the respective font, if available.

+\beginsection {Font names database}
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+
+\label{sec:fontdb}
+
+As mentioned above, \identifier{luaotfload} keeps track of which
+fonts are available to \LUATEX by means of a \emphasis{database}.
+%
+This allows referring to fonts not only by explicit filenames but
+also by the proper names contained in the metadata which is often
+more accessible to humans.\footnote{%
+ The tool \hyperlink[\fileent{otfinfo}]{http://www.lcdf.org/type/}
+ (comes with \TEX Live), when invoked on a font file with the
+ \inlinecode {-i} option, lists the variety of name fields defined for
+ it.
+}
+
+When \identifier{luaotfload} is asked to load a font by a font name,
+it will check if the database exists and load it, or else generate a
+fresh one.
+%
+Should it then fail to locate the font, an update to the database is
+performed in case the font has been added to the system only
+recently.
+%
+As soon as the database is updated, the resolver will try
+and look up the font again, all without user intervention.
+%
+The goal is for \identifier{luaotfload} to act in the background and
+behave as unobtrusively as possible, while providing a convenient
+interface to the fonts installed on the system.
+
+Generating the database for the first time may take a while since it
+inspects every font file on your computer.
+%
+This is particularly noticeable if it occurs during a typesetting run.
+In any case, subsequent updates to the database will be quite fast.
+
+\beginsubsection[luaotfload-tool]
+ {\fileent{luaotfload-tool}}
+
+It can still be desirable at times to do some of these steps
+manually, and without having to compile a document.
+%
+To this end, \identifier{luaotfload} comes with the utility
+\fileent{luaotfload-tool} that offers an interface to the database
+functionality.
+%
+Being a \LUA script, there are two ways to run it:
+either make it executable (\inlinecode {chmod +x} on unixoid systems) or
+pass it as an argument to \fileent{texlua}.\footnote{%
+ Tests by the maintainer show only marginal performance gain by
+ running with Luigi Scarso’s
+ \hyperlink [\identifier{Luajit\kern-.25ex\TEX}]{https://foundry.supelec.fr/projects/luajittex/},
+ which is probably due to the fact that most of the time is spent
+ on file system operations.
+
+ \emphasis{Note}:
+ On \abbrev{MS} \identifier{Windows} systems, the script can be run
+ either by calling the wrapper application
+ \fileent{luaotfload-tool.exe} or as
+ \inlinecode {texlua.exe luaotfload-tool.lua}.
+}
+%
+Invoked with the argument \inlinecode {--update} it will perform a database
+update, scanning for fonts not indexed.
+
+\beginlisting
+ luaotfload-tool --update
+\endlisting
+
+Adding the \inlinecode {--force} switch will initiate a complete
+rebuild of the database.
+
+\beginlisting
+ luaotfload-tool --update --force
+\endlisting
+
+\endsubsection
+
+\beginsubsection{Search Paths}
+
+\identifier{luaotfload} scans those directories where fonts are
+expected to be located on a given system.
+%
+On a Linux machine it follows the paths listed in the
+\identifier{Fontconfig} configuration files;
+consult \inlinecode {man 5 fonts.conf} for further information.
+%
+On \identifier{Windows} systems, the standard location is
+\inlinecode {Windows\\Fonts},
+%
+while \identifier{Mac OS~X} requires a multitude of paths to
+be examined.
+%
+The complete list is is given in table \ref{table-searchpaths}.
+Other paths can be specified by setting the environment variable
+\inlinecode {OSFONTDIR}.
+%
+If it is non-empty, then search will be extended to the included
+directories.

+
+\beginsubsection{Querying from Outside}
+
+\fileent{luaotfload-tool} also provides rudimentary means of
+accessing the information collected in the font database.
+%
+If the option \inlinecode {--find=}\emphasis{name} is given, the script will
+try and search the fonts indexed by \identifier{luaotfload} for a
+matching name.
+%
+For instance, the invocation
+
+\beginlisting
+ luaotfload-tool --find="Iwona Regular"
+\endlisting
+
+\noindent
+will verify if “Iwona Regular” is found in the database and can be
+readily requested in a document.
+
+If you are unsure about the actual font name, then add the
+\inlinecode {-F} (or \inlinecode {--fuzzy}) switch to the command line to enable
+approximate matching.
+%
+Suppose you cannot precisely remember if the variant of
+\identifier{Iwona} you are looking for was “Bright” or “Light”.
+The query
+
+\beginlisting
+ luaotfload-tool -F --find="Iwona Bright"
+\endlisting
+
+\noindent
+will tell you that indeed the latter name is correct.
+
+Basic information about fonts in the database can be displayed
+using the \inlinecode {-i} option (\inlinecode {--info}).
+%
+\beginlisting
+ luaotfload-tool -i --find="Iwona Light Italic"
+\endlisting
+%
+\noindent
+The meaning of the printed values is described in section 4.4 of the
+\LUATEX reference manual.\footnote{%
+ In \TEX Live: \fileent{texmf-dist/doc/luatex/base/luatexref-t.pdf}.
+}
+
+For a much more detailed report about a given font try the
+\inlinecode {-I} option instead (\inlinecode {--inspect}).
+\beginlisting
+ luaotfload-tool -I --find="Iwona Light Italic"
+\endlisting
+
+\inlinecode {luaotfload-tool --help} will list the available command line
+switches, including some not discussed in detail here.
+%
+For a full documentation of \identifier{luaotfload-tool} and its
+capabilities refer to the manpage
+(\inlinecode {man 1 luaotfload-tool}).\footnote{%
+ Or see \inlinecode {luaotfload-tool.rst} in the source directory.
+}
+
+\endsubsection
+
+\beginsubsection {Blacklisting Fonts}
+\label{font-blacklist}
+
+Some fonts are problematic in general, or just in \LUATEX.
+%
+If you find that compiling your document takes far too long or eats
+away all your system’s memory, you can track down the culprit by
+running \inlinecode {luaotfload-tool -v} to increase verbosity.
+%
+Take a note of the \emphasis{filename} of the font that database
+creation fails with and append it to the file
+\fileent{luaotfload-blacklist.cnf}.
+
+A blacklist file is a list of font filenames, one per line.
+Specifying the full path to where the file is located is optional, the
+plain filename should suffice.
+%
+File extensions (\fileent{.otf}, \fileent{.ttf}, etc.) may be omitted.
+%
+Anything after a percent (\inlinecode {\%}) character until the end of the line
+is ignored, so use this to add comments.
+%
+Place this file to some location where the \identifier{kpse}
+library can find it, e.~g.
+\fileent{texmf-local/tex/luatex/luaotfload} if you are running
+\identifier{\TEX Live},\footnote{%
+ You may have to run \inlinecode {mktexlsr} if you created a new file in
+ your \fileent{texmf} tree.
+}
+or just leave it in the working directory of your document.
+%
+\identifier{luaotfload} reads all files named
+\fileent{luaotfload-blacklist.cnf} it finds, so the fonts in
+\fileent{./luaotfload-blacklist.cnf} extend the global blacklist.
+
+Furthermore, a filename prepended with a dash character (\inlinecode{-}) is
+removed from the blacklist, causing it to be temporarily whitelisted
+without modifying the global file.
+%
+An example with explicit paths:
+
+\beginlisting
+% example otf-blacklist.cnf
+/Library/Fonts/GillSans.ttc % Luaotfload ignores this font.
+-/Library/Fonts/Optima.ttc % This one is usable again, even if
+ % blacklisted somewhere else.

+\beginsection {The Fontloader}
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+
+\beginsubsection {Overview}
+
+To a large extent, \identifier{luaotfload} relies on code originally
+written by Hans Hagen for the
+\hyperlink[\identifier{\CONTEXT}]{http://wiki.contextgarden.net}
+format.
+%
+It integrates the font loader, written entirely in \LUA, as distributed
+in the \identifier{\LUATEX-Fonts} package.
+%
+The original \LUA source files have been combined using the \CONTEXT
+packaging library into a single, self-contained blob. In
+this form the font loader depends only on the \identifier{lualibs}
+package and requires only minor adaptions to integrate into
+\identifier{luaotfload}.
+
+The guiding principle is to let \CONTEXT/\LUATEX-Fonts take care of the
+implementation, and update the imported code as frequently as
+necessary.
+%
+As maintainers, we aim at importing files from upstream essentially
+\emphasis{unmodified}, except for renaming them to prevent name
+clashes.
+%
+This job has been greatly alleviated since the advent of
+\LUATEX-Fonts, prior to which the individual dependencies had to be
+manually spotted and extracted from the \CONTEXT source code in a
+complicated and error-prone fashion.
+
+\endsubsection
+
+\beginsubsection {Contents and Dependencies}
+
+Below is a commented list of the files distributed with
+\identifier{luaotfload} in one way or the other.
+%
+See see the figure on page \pageref{file-graph} for a
+graphical representation of the dependencies.
+%
+\label{package}%
+Through the script \fileent{mkimport} a \CONTEXT library
+is invoked to create the \identifier{luaotfload} fontloader as a merged
+(amalgamated) source file.\footnote{%
+ In \CONTEXT, this facility can be accessed by means of a
+ \hyperlink[script]{https://bitbucket.org/phg/context-mirror/src/beta/scripts/context/lua/mtx-package.lua?at=beta}
+ which is integrated into \fileent{mtxrun} as a subcommand.
+ Run \inlinecode {mtxrun --script package --help} to display further
+ information.
+ For the actual merging code see the file
+ \fileent{util-mrg.lua} that is part of \CONTEXT.
+}
+%
+This file constitutes the “default fontloader” and is part of the
+\identifier{luaotfload} package as \fileent{fontloader-YY-MM-DD.lua},
+where the uppercase letters are placeholders for the build date.
+%
+A companion to it, \fileent{luatex-basics-gen.lua} (renamed to \fileent{fontloader-basics-gen.lua} in \identifier{luaotfload})
+must be loaded beforehand to set up parts of the environment required by the \CONTEXT
+libraries.
+%
+During a \TEX\ run, the fontloader initialization and injection happens
+in the module \fileent{luaotfload-init.lua}.
+%
+Additionally, the “reference fontloader” as imported from \LUATEX-Fonts
+is provided as the file \fileent{fontloader-reference.lua}.
+%
+This file is self-contained in that it packages all the auxiliary \LUA
+libraries too, as Luaotfload did up to the 2.5 series; since that job
+has been offloaded to the \identifier{Lualibs} package, loading this
+fontloader introduces a certain code duplication.
+
+A number of \emphasis{\LUA utility libraries} are not part of the
+\identifier{luaotfload} fontloader, contrary to its equivalent in
+\LUATEX-Fonts. These are already provided by the \identifier{lualibs}
+and have thus been omitted from the merge.\footnote{%
+ Faithful listeners will remember the pre-2.6 era when the fontloader
+ used to be integrated as-is which caused all kinds of code
+ duplication with the pervasive \identifier{lualibs} package.
+ This conceptual glitch has since been amended by tightening the
+ coupling with the excellent \CONTEXT\ toolchain.
+}
+
+\begindoublecolumns
+ \begindefinitions
+ \directlua{ printctxlibslist ()}
+ \enddefinitions
+\enddoublecolumns
+
+The reference fontloader is home to several \LUA files that can be
+grouped twofold as below:
+
+\begindefinitions
+ \beginnormalitem
+ The \emphasis{font loader} itself.
+ These files have been written for \LUATEX-Fonts and they are
+ distributed along with \identifier{luaotfload} so as to resemble
+ the state of the code when it was imported. Their purpose is either
+ to give a slightly aged version of a file if upstream considers
+ latest developments for not yet ready for use outside Context; or,
+ to install placeholders or minimalist versions of APIs relied upon
+ but usually provided by parts of Context not included in the
+ fontloader.
+ \begindoublecolumns
+ \begindefinitions
+ \directlua{printctxallgenericlist ()}
+ \enddefinitions
+ \enddoublecolumns
+ \endnormalitem
+
+ \beginnormalitem
+ Code related to \emphasis{font handling and node processing}, taken
+ directly from \CONTEXT.
+ \begindoublecolumns
+ \begindefinitions
+ \directlua{printctxfontlist ()}
+ \enddefinitions
+ \enddoublecolumns
+ \endnormalitem
+\enddefinitions
+
+As an alternative to the merged file, \identifier {Luaotfload} may load
+individual unpackaged \LUA libraries that come with the source, or even
+use the files from Context directly.
+%
+Thus if you prefer running bleeding edge code from the \CONTEXT beta,
+choose the \inlinecode {context} fontloader via the configuration file
+(see sections \ref{sec:conf} and \ref{sec:pkg} below).
+
+Also, the merged file at some point loads the Adobe Glyph List from a
+\LUA table that is contained in \fileent{luaotfload-glyphlist.lua},
+which is automatically generated by the script
+\fileent{mkglyphlist}.\footnote{%
+ See \fileent{luaotfload-font-enc.lua}.
+ The hard-coded file name is why we have to replace the procedure
+ that loads the file in \fileent{luaotfload-init.lua}.
+}
+%
+There is a make target \identifier{glyphs} that will create a fresh
+glyph list so we don’t need to import it from \CONTEXT any longer.
+
+In addition to these, \identifier{luaotfload} requires a number of
+files not contained in the merge. Some of these have no equivalent in
+\LUATEX-Fonts or \CONTEXT, some were taken unmodified from the latter.

+\endsubsection
+
+\beginsubsection {Packaging}
+
+\label{sec:pkg}%
+The fontloader code is integrated as an isolated component that can be
+switched out on demand.
+%
+To specify the fontloader you wish to use, the configuration file
+(described in section \ref{sec:conf}) provides the option
+\inlinecode{fontloader}.
+%
+Its value can be one of the identifiers \inlinecode{default} or
+\inlinecode{reference} (see above, section \ref{package}) or the name
+of a file somewhere in the search path of \LUATEX.
+%
+This will make \identifier {Luaotfload} locate the \CONTEXT source by
+means of \identifier{kpathsea} lookups and use those instead of the
+merged package.
+%
+The parameter may be extended with a path to the \CONTEXT
+\fileent{texmf}, separated with a colon:
+
+\beginlisting
+[run]
+ fontloader = context:~/context/tex/texmf-context
+\endlisting
+
+\noindent This setting allows accessing an installation -- e. g. the
+standalone distribution or a source repository -- outside the current
+\TEX distribution.
+
+Like the \identifier{Lualibs} package, the fontloader is deployed as a
+\emphasis{merged package} containing a series of \LUA files joined
+together in their expected order and stripped of non-significant parts.
+%
+The \fileent{mkimport} utility assists in pulling the files from a
+\CONTEXT tree and packaging them for use with \identifier{Luaotfload}.%
+%
+The state of the files currently in \identifier{Luaotfload}’s
+repository can be queried:
+\beginlisting
+./scripts/mkimport news
+\endlisting
+%
+The subcommand for importing takes the prefix of the desired \CONTEXT
+\identifier{texmf} as an optional argument:
+\beginlisting
+./scripts/mkimport import ~/context/tex/texmf-context
+\endlisting
+%
+Whereas the command for packaging requires a path to the
+\emphasis{package description file} and the output name to be passed.
+\beginlisting
+./scripts/mkimport package fontloader-custom.lua
+\endlisting
+
+From the toplevel makefile, the targets \inlinecode{import} and
+\inlinecode{package} provide easy access to the commands as invoked during
+the \identifier{Luaotfload} build process.\footnote{%
+ \emphasis{Hint for those interested in the packaging process}: issue
+ \inlinecode{make show} for a list of available build routines.
+}
+These will call \inlinecode{mkimport} script with the correct
+parameters to generate a datestamped package.
+%
+Whether files have been updated in the upstream distribution can be
+queried by \inlinecode{./scripts/mkimport news}.
+%
+This will compare the imported files with their counterparts in the
+\CONTEXT distribution and report changes.
+

+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+\beginsection {Configuration Files}
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+
+\beginnarrower
+ \emphasis{Caution}: For the authoritative documentation, consult the
+ manpage for \fileent{luaotfload.conf(5)}.
+\endnarrower
+
+\label{sec:conf}
+The runtime behavior of \identifier{Luaotfload} can be customized by
+means of a configuration file.
+% location
+At startup, it attempts to locate a file called \fileent
+{luaotfload.conf} or \fileent {luaotfloadrc} at a number of candidate
+locations:
+
+\begincentered
+ \begindefinitions
+ \beginnormalitem \fileent{./luaotfload.conf} \endnormalitem
+ \beginnormalitem \fileent{./luaotfloadrc} \endnormalitem
+ \beginnormalitem \fileent{\$XDG_CONFIG_HOME/luaotfload/luaotfload.conf} \endnormalitem
+ \beginnormalitem \fileent{\$XDG_CONFIG_HOME/luaotfload/luaotfload.rc} \endnormalitem
+ \beginnormalitem \fileent{~/.luaotfloadrc} \endnormalitem
+ \enddefinitions
+\endcentered
+
+\beginnarrower
+ \emphasis{Caution}: The configuration potentially modifies the final
+ document. A project-local file belongs under version control along
+ with the rest of the document. This is to ensure that everybody who
+ builds the project also receives the same customizations as the
+ author.
+\endnarrower
+
+% syntax
+The syntax is fairly close to the format used by
+\fileent{git-config(1)} which in turn was derived from the popular
+\identifier{.INI} format: Lines of key-value pairs are grouped under
+different configuration “sections”.\footnote{%
+ The configuration parser in \fileent {luoatfload-parsers.lua} might
+ be employed by other packages for similar purposes.
+}
+% example settings
+An example for customization via \fileent {luaotfload.conf} might look
+as below:
+
+\beginlisting
+; Example luaotfload.conf containing a rudimentary configuration
+[db]
+ update-live = false
+[run]
+ color-callback = pre_linebreak_filter
+ definer = info_patch
+ log-level = 5
+[default-features]
+ global = mode=base
+\endlisting
+
+This specifies that for the given project, \identifier{Luaotfload}
+shall not attempt to automatically scan for fonts if it can’t resolve a
+request. The font-based colorization will happen during \LUATEX’s
+pre-linebreak filter. The fontloader will output verbose information
+about the fonts at definition time along with globally increased
+verbosity. Lastly, the fontloader defaults to the less expensive
+\luaident{base} mode like it does in \CONTEXT.
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+\beginsection {Auxiliary Functions}
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+
+With release version 2.2, \identifier{Luaotfload} received
+additional functions for package authors to call from outside
+(see the file \fileent{luaotfload-auxiliary.lua} for details).
+%
+The purpose of this addition twofold.
+%
+Firstly, \identifier{luaotfload} failed to provide a stable interface
+to internals in the past which resulted in an unmanageable situation
+of different packages abusing the raw access to font objects by means
+of the \luaident{patch_font} callback.
+%
+When the structure of the font object changed due to an update, all
+of these imploded and several packages had to be fixed while
+simultaneously providing fallbacks for earlier versions.
+%
+Now the patching is done on the \identifier{luaotfload} side and can
+be adapted with future modifications to font objects without touching
+the packages that depend on it.
+%
+Second, some the capabilities of the font loader and the names
+database are not immediately relevant in \identifier{luaotfload}
+itself but might nevertheless be of great value to package authors or
+end users.
+
+Note that the current interface is not yet set in stone and the
+development team is open to suggestions for improvements or
+additions.
+
+\beginsubsection {Callback Functions}
+
+The \luaident{patch_font} callback is inserted in the wrapper
+\identifier{luaotfload} provides for the font definition callback.
+%
+At this place it allows manipulating the font object immediately after
+the font loader is done creating it.
+%
+For a short demonstration of its usefulness, here is a snippet that
+writes an entire font object to the file \fileent{fontdump.lua}:
+
+\beginlisting
+ \input luaotfload.sty
+ \directlua{
+ local dumpfile = "fontdump.lua"
+ local dump_font = function (tfmdata)
+ local data = table.serialize(tfmdata)
+ io.savedata(dumpfile, data)
+ end
+
+ luatexbase.add_to_callback(
+ "luaotfload.patch_font",
+ dump_font,
+ "my_private_callbacks.dump_font"
+ )
+ }
+ \font \dumpme = name:Iwona
+ \bye
+\endlisting
+
+\emphasis{Beware}: this creates a Lua file of around 150,000 lines of
+code, taking up 3~\abbrev{mb} of disk space.
+%
+By inspecting the output you can get a first impression of how a font
+is structured in \LUATEX’s memory, what elements it is composed of,
+and in what ways it can be rearranged.
+
+\beginsubsubsection {Compatibility with Earlier Versions}
+
+As has been touched on in the preface to this section, the structure
+of the object as returned by the fontloader underwent rather drastic
+changes during different stages of its development, and not all
+packages that made use of font patching have kept up with every one
+of it.
+%
+To ensure compatibility with these as well as older versions of
+some packages, \identifier{luaotfload} sets up copies of or references
+to data in the font table where it used to be located.
+%
+For instance, important parameters like the requested point size, the
+units factor, and the font name have again been made accessible from
+the toplevel of the table even though they were migrated to different
+subtables in the meantime.
+
+\endsubsubsection
+
+\beginsubsubsection{Patches}
+
+These are mostly concerned with establishing compatibility with \XETEX.
+
+\beginfunctionlist
+
+ \beginaltitem {set_sscale_dimens}

+\beginsection {Troubleshooting}
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+
+\beginsubsection {Database Generation}
+
+If you encounter problems with some fonts, please first update to the
+latest version of this package before reporting a bug, as
+\identifier{luaotfload} is under active development and still a moving
+target.
+%
+The development takes place on \identifier{github} at
+\hyperlink {https://github.com/lualatex/luaotfload} where there is an issue
+tracker for submitting bug reports, feature requests and the likes.
+
+Bug reports are more likely to be addressed if they contain the output
+of
+
+\beginlisting
+ luaotfload-tool --diagnose=environment,files,permissions
+\endlisting
+
+\noindent Consult the man page for a description of these options.
+
+Errors during database generation can be traced by increasing the
+verbosity level and redirecting log output to \fileent{stdout}:
+
+\beginlisting
+ luaotfload-tool -fuvvv --log=stdout
+\endlisting
+
+\noindent or to a file in \fileent{/tmp}:
+
+\beginlisting
+ luaotfload-tool -fuvvv --log=file
+\endlisting
+
+\noindent In the latter case, invoke the \inlinecode {tail(1)} utility on the
+file for live monitoring of the progress.
+
+If database generation fails, the font last printed to the terminal or
+log file is likely to be the culprit.
+%
+Please specify it when reporting a bug, and blacklist it for the time
+being (see above, page \pageref{font-blacklist}).
+
+\endsubsection
+
+\beginsubsection {Font Features}
+
+A common problem is the lack of features for some
+\OpenType fonts even when specified.
+%
+This can be related to the fact that some fonts do not provide features
+for the \inlinecode {dflt} script (see above on page \pageref{script-tag}),
+which is the default one in this package.
+%
+If this happens, assigning a noth script when the font is defined should
+fix it.
+%
+For example with \inlinecode {latn}:
+
+\beginlisting
+ \font \test = file:MyFont.otf:script=latn;+liga;
+\endlisting
+
+You can get a list of features that a font defines for scripts and
+languages by querying it in \fileent{luaotfload-tool}:
+
+\beginlisting
+ luaotfload-tool --find="Iwona" --inspect
+\endlisting
+
+\endsubsection
+
+\beginsubsection {\LUATEX Programming}
+
+Another strategy that helps avoiding problems is to not access raw
+\LUATEX internals directly.
+%
+Some of them, even though they are dangerous to access, have not been
+overridden or disabled.
+%
+Thus, whenever possible prefer the functions in the \luaident{aux}
+namespace over direct manipulation of font objects. For example, raw
+access to the \luaident{font.fonts} table like:
+
+\beginlisting
+ local somefont = font.fonts[2]
+\endlisting
+
+\noindent can render already defined fonts unusable.
+%
+Instead, the function \luaident{font.getfont()} should be used
+because it has been replaced by a safe variant.
+
+However, \luaident{font.getfont()} only covers fonts handled by the
+font loader, e.~g. \identifier{OpenType} and \identifier{TrueType}
+fonts, but not \abbrev{tfm} or \abbrev{ofm}.
+%
+Should you absolutely require access to all fonts known to \LUATEX,
+including the virtual and autogenerated ones, then you need to query
+both \luaident{font.getfont()} and \luaident{font.fonts}.
+%
+In this case, best define you own accessor:
+
+\beginlisting
+ local unsafe_getfont = function (id)
+ local tfmdata = font.getfont (id)
+ if not tfmdata then
+ tfmdata = font.fonts[id]
+ end
+ return tfmdata
+ end
+
+ --- use like getfont()
+ local somefont = unsafe_getfont (2)
+\endlisting
+

+DESCRIPTION
+=======================================================================
+
+luaotfload-tool accesses the font names database that is required by
+the *Luaotfload* package. There are two general modes: **update** and
+**query**.
+
++ **update**: update the database or rebuild it entirely;
++ **query**: resolve a font name or display close matches.
+
+OPTIONS
+=======================================================================
+
+update mode
+-----------------------------------------------------------------------
+--update, -u Update the database; indexes new fonts.
+--force, -f Force rebuilding of the database; re-indexes
+ all fonts.
+--local, -L Include font files in ``$PWD``. This option
+ will cause large parts of the database to be
+ rebuilt. Thus it is quite inefficient.
+ Additionally, if local font files are found,
+ the database is prevented from being saved
+ to disk, so the local fonts need to be parsed
+ with every invocation of ``luaotfload-tool``.
+--no-reload, -n Suppress auto-updates to the database (e.g.
+ when ``--find`` is passed an unknown name).
+--no-compress, -c Do not filter the plain text version of the
+ font index through gzip. Useful for debugging
+ if your editor is built without zlib.
+
+--prefer-texmf, -p Organize the file name database in a way so
+ that it prefer fonts in the *TEXMF* tree over
+ system fonts if they are installed in both.
+--formats=EXTENSIONS Extensions of the font files to index.
+ Where *EXTENSIONS* is a comma-separated list of
+ supported file extensions (otf, ttf, ttc).
+ If the list is prefixed
+ with a ``+`` sign, the given list is added to
+ the currently active one; ``-`` subtracts.
+ Default: *otf,ttf,ttc*.
+ Examples:
+
+ 1) ``--formats=-ttc,ttf`` would skip
+ TrueType fonts and font collections;
+ 2) ``--formats=otf`` would scan only OpenType
+ files;
+ 3) ``--formats=+afm`` includes binary
+ Postscript files accompanied by an AFM file.
+
+query mode
+-----------------------------------------------------------------------
+--find=NAME Resolve a font name; this looks up <name> in
+ the database and prints the file name it is
+ mapped to.
+ ``--find`` also understands request syntax,
+ i.e. ``--find=file:foo.otf`` checks whether
+ ``foo.otf`` is indexed.
+--fuzzy, -F Show approximate matches to the file name if
+ the lookup was unsuccessful (requires
+ ``--find``).
+
+--info, -i Display basic information to a resolved font
+ file (requires ``--find``).
+--inspect, -I Display detailed information by loading the
+ font and analyzing the font table; very slow!
+ For the meaning of the returned fields see
+ the LuaTeX documentation.
+ (requires ``--find``).
+
+--list=CRITERION Show entries, where *CRITERION* is one of the
+ following:
+
+ 1) the character ``*``, selecting all entries;
+ 2) a field of a database entry, for instance
+ *version* or *format**, according to which
+ the output will be sorted.
+ Information in an unstripped database (see
+ the option ``--no-strip`` above) is nested:
+ Subfields of a record can be addressed using
+ the ``->`` separator, e. g.
+ ``file->location``, ``style->units_per_em``,
+ or
+ ``names->sanitized->english->prefmodifiers``.
+ NB: shell syntax requires that arguments
+ containing ``->`` be properly quoted!
+ 3) an expression of the form ``field:value`` to
+ limit the output to entries whose ``field``
+ matches ``value``.
+
+ For example, in order to output file names and
+ corresponding versions, sorted by the font
+ format::
+
+ ./luaotfload-tool.lua --list="format" --fields="file->base,version"
+
+ This prints::
+
+ otf latinmodern-math.otf Version 1.958
+ otf lmromancaps10-oblique.otf 2.004
+ otf lmmono8-regular.otf 2.004
+ otf lmmonoproplt10-bold.otf 2.004
+ otf lmsans10-oblique.otf 2.004
+ otf lmromanslant8-regular.otf 2.004
+ otf lmroman12-italic.otf 2.004
+ otf lmsansdemicond10-oblique.otf 2.004
+ ...
+
+--fields=FIELDS Comma-separated list of fields that should be
+ printed.
+ Information in an unstripped database (see the
+ option ``--no-strip`` above) is nested:
+ Subfields of a record can be addressed using
+ the ``->`` separator, e. g.
+ ``file->location``, ``style->units_per_em``,
+ or ``names->sanitized->english->subfamily``.
+ The default is plainname,version*.
+ (Only meaningful with ``--list``.)
+
+font and lookup caches
+-----------------------------------------------------------------------
+--flush-lookups Clear font name lookup cache (experimental).
+
+--cache=DIRECTIVE Cache control, where *DIRECTIVE* is one of the
+ following:
+
+ 1) ``purge`` -> delete Lua files from cache;
+ 2) ``erase`` -> delete Lua and Luc files from
+ cache;
+ 3) ``show`` -> print stats.
+
+debugging methods
+-----------------------------------------------------------------------
+--show-blacklist, -b Show blacklisted files (not directories).
+--dry-run, -D Don’t load fonts when updating the database;
+ scan directories only.
+ (For debugging file system related issues.)
+--no-strip Do not strip redundant information after
+ building the database. Warning: this will
+ inflate the index to about two to three times
+ the normal size.
+--max-fonts=N Process at most *N* font files, including fonts
+ already indexed in the count.
+--bisect=DIRECTIVE Bisection of the font database.
+ This mode is intended as assistance in
+ debugging the Luatex engine, especially when
+ tracking memleaks or buggy fonts.
+
+ *DIRECTIVE* can be one of the following:
+
+ 1) ``run`` -> Make ``luaotfload-tool`` respect
+ the bisection progress when running.
+ Combined with ``--update`` and possibly
+ ``--force`` this will only process the files
+ from the start up until the pivot and ignore
+ the rest.
+ 2) ``start`` -> Start bisection: create a
+ bisection state file and initialize the low,
+ high, and pivot indices.
+ 3) ``stop`` -> Terminate the current bisection
+ session by deleting the state file.
+ 4) ``good`` | ``bad`` -> Mark the section
+ processed last as “good” or “bad”,
+ respectively. The next bisection step will
+ continue with the bad section.
+ 5) ``status`` -> Print status information about
+ the current bisection session. Hint: Use
+ with higher verbosity settings for more
+ output.
+
+ A bisection session is initiated by issuing the
+ ``start`` directive. This sets the pivot to the
+ middle of the list of available font files.
+ Now run *luaotfload-tool* with the ``--update``
+ flag set as well as ``--bisect=run``: only the
+ fonts up to the pivot will be considered. If
+ that task exhibited the issue you are tracking,
+ then tell Luaotfload using ``--bisect=bad``.
+ The next step of ``--bisect=run`` will continue
+ bisection with the part of the files below the
+ pivot.
+ Likewise, issue ``--bisect=good`` in order to
+ continue with the fonts above the pivot,
+ assuming the tested part of the list did not
+ trigger the bug.
+
+ Once the culprit font is tracked down, ``good``
+ or ``bad`` will have no effect anymore. ``run``
+ will always end up processing the single font
+ file that was left.
+ Use ``--bisect=stop`` to clear the bisection
+ state.
+
+miscellaneous
+-----------------------------------------------------------------------
+--verbose=N, -v Set verbosity level to *n* or the number of
+ repetitions of ``-v``.
+--quiet No verbose output (log level set to zero).
+--log=CHANNEL Redirect log output (for database
+ troubleshooting), where *CHANNEL* can be
+
+ 1) ``stdout`` -> all output will be
+ dumped to the terminal (default); or
+ 2) ``file`` -> write to a file to the temporary
+ directory (the name will be chosen
+ automatically.
+
+--version, -V Show version numbers of components as well as
+ some basic information and exit.
+--help, -h Show help message and exit.
+
+--diagnose=CHECK Run the diagnostic procedure *CHECK*. Available
+ procedures are:
+
+ 1) ``files`` -> check *Luaotfload* files for
+ modifications;
+ 2) ``permissions`` -> check permissions of
+ cache directories and files;
+ 3) ``environment`` -> print relevant
+ environment and kpse variables;
+ 4) ``repository`` -> check the git repository
+ for new releases,
+ 5) ``index`` -> check database, display
+ information about it.
+
+ Procedures can be chained by concatenating with
+ commas, e.g. ``--diagnose=files,permissions``.
+ Specify ``thorough`` to run all checks.
+
+--conf=FILE Read the configuration from *FILE*. See
+ **luaotfload.conf**\(%) for documentation
+ concerning the format and available options.
+--dumpconf Print the currently active configuration; the
+ output can be saved to a file and used for
+ bootstrapping a custom configuration files.
+
+FILES
+=======================================================================
+
+The font name database is usually located in the directory
+``texmf-var/luatex-cache/generic/names/`` (``$TEXMFCACHE`` as set in
+``texmf.cnf``) of your *TeX Live* distribution as a zlib-compressed
+file ``luaotfload-names.lua.gz``.
+The experimental lookup cache will be created as
+``luaotfload-lookup-cache.lua`` in the same directory.
+These Lua tables are not used directly by Luaotfload, though.
+Instead, they are compiled to Lua bytecode which is written to
+corresponding files with the extension ``.luc`` in the same directory.
+When modifying the files by hand keep in mind that only if the bytecode
+files are missing will Luaotfload use the plain version instead.
+Both kinds of files are safe to delete, at the cost of regenerating
+them with the next run of *LuaTeX*.

+\section{DESCRIPTION%
+ \label{description}%
+}
+
+luaotfload-tool accesses the font names database that is required by
+the \emph{Luaotfload} package. There are two general modes: \textbf{update} and
+\textbf{query}.
+
+\begin{itemize}
+\item \textbf{update}: update the database or rebuild it entirely;
+
+\item \textbf{query}: resolve a font name or display close matches.
+\end{itemize}
+
+
+\section{OPTIONS%
+ \label{options}%
+}
+
+
+\subsection{update mode%
+ \label{update-mode}%
+}
+
+\begin{DUoptionlist}
+\item[--update, -u] Update the database; indexes new fonts.
+
+\item[--force, -f] Force rebuilding of the database; re-indexes
+all fonts.
+
+\item[--local, -L] Include font files in \texttt{\$PWD}. This option
+will cause large parts of the database to be
+rebuilt. Thus it is quite inefficient.
+Additionally, if local font files are found,
+the database is prevented from being saved
+to disk, so the local fonts need to be parsed
+with every invocation of \texttt{luaotfload-tool}.
+
+\item[--no-reload, -n] Suppress auto-updates to the database (e.g.
+when \texttt{--find} is passed an unknown name).
+
+\item[--no-compress, -c] Do not filter the plain text version of the
+font index through gzip. Useful for debugging
+if your editor is built without zlib.
+
+\item[--prefer-texmf, -p] Organize the file name database in a way so
+that it prefer fonts in the \emph{TEXMF} tree over
+system fonts if they are installed in both.
+
+\item[--formats=EXTENSIONS] Extensions of the font files to index.
+Where \emph{EXTENSIONS} is a comma-separated list of
+supported file extensions (otf, ttf, ttc).
+If the list is prefixed
+with a \texttt{+} sign, the given list is added to
+the currently active one; \texttt{-} subtracts.
+Default: \emph{otf,ttf,ttc}.
+Examples:
+
+\begin{enumerate}
+\renewcommand{\labelenumi}{\arabic{enumi})}
+\item \texttt{--formats=-ttc,ttf} would skip
+TrueType fonts and font collections;
+
+\item \texttt{--formats=otf} would scan only OpenType
+files;
+
+\item \texttt{--formats=+afm} includes binary
+Postscript files accompanied by an AFM file.
+\end{enumerate}
+\end{DUoptionlist}
+
+
+\subsection{query mode%
+ \label{query-mode}%
+}
+
+\begin{DUoptionlist}
+\item[--find=NAME] Resolve a font name; this looks up <name> in
+the database and prints the file name it is
+mapped to.
+\texttt{--find} also understands request syntax,
+i.e. \texttt{--find=file:foo.otf} checks whether
+\texttt{foo.otf} is indexed.
+
+\item[--fuzzy, -F] Show approximate matches to the file name if
+the lookup was unsuccessful (requires
+\texttt{--find}).
+
+\item[--info, -i] Display basic information to a resolved font
+file (requires \texttt{--find}).
+
+\item[--inspect, -I] Display detailed information by loading the
+font and analyzing the font table; very slow!
+For the meaning of the returned fields see
+the LuaTeX documentation.
+(requires \texttt{--find}).
+
+\item[--list=CRITERION] Show entries, where \emph{CRITERION} is one of the
+following:
+
+\begin{enumerate}
+\renewcommand{\labelenumi}{\arabic{enumi})}
+\item the character \texttt{*}, selecting all entries;
+
+\item a field of a database entry, for instance
+\emph{version} or \emph{format*}, according to which
+the output will be sorted.
+Information in an unstripped database (see
+the option \texttt{--no-strip} above) is nested:

+
+\begin{DUoptionlist}
+\item[--show-blacklist, -b] Show blacklisted files (not directories).
+
+\item[--dry-run, -D] Don’t load fonts when updating the database;
+scan directories only.
+(For debugging file system related issues.)
+
+\item[--no-strip] Do not strip redundant information after
+building the database. Warning: this will
+inflate the index to about two to three times
+the normal size.
+
+\item[--max-fonts=N] Process at most \emph{N} font files, including fonts
+already indexed in the count.
+
+\item[--bisect=DIRECTIVE] Bisection of the font database.
+This mode is intended as assistance in
+debugging the Luatex engine, especially when
+tracking memleaks or buggy fonts.
+
+\emph{DIRECTIVE} can be one of the following:
+
+\begin{enumerate}
+\renewcommand{\labelenumi}{\arabic{enumi})}
+\item \texttt{run} -> Make \texttt{luaotfload-tool} respect
+the bisection progress when running.
+Combined with \texttt{--update} and possibly
+\texttt{--force} this will only process the files
+from the start up until the pivot and ignore
+the rest.
+
+\item \texttt{start} -> Start bisection: create a
+bisection state file and initialize the low,
+high, and pivot indices.
+
+\item \texttt{stop} -> Terminate the current bisection
+session by deleting the state file.
+
+\item \texttt{good} | \texttt{bad} -> Mark the section
+processed last as “good” or “bad”,
+respectively. The next bisection step will
+continue with the bad section.
+
+\item \texttt{status} -> Print status information about
+the current bisection session. Hint: Use
+with higher verbosity settings for more
+output.
+\end{enumerate}
+
+A bisection session is initiated by issuing the
+\texttt{start} directive. This sets the pivot to the
+middle of the list of available font files.
+Now run \emph{luaotfload-tool} with the \texttt{--update}
+flag set as well as \texttt{--bisect=run}: only the
+fonts up to the pivot will be considered. If
+that task exhibited the issue you are tracking,
+then tell Luaotfload using \texttt{--bisect=bad}.
+The next step of \texttt{--bisect=run} will continue
+bisection with the part of the files below the
+pivot.
+Likewise, issue \texttt{--bisect=good} in order to
+continue with the fonts above the pivot,
+assuming the tested part of the list did not
+trigger the bug.
+
+Once the culprit font is tracked down, \texttt{good}
+or \texttt{bad} will have no effect anymore. \texttt{run}
+will always end up processing the single font
+file that was left.
+Use \texttt{--bisect=stop} to clear the bisection
+state.

+
+The font name database is usually located in the directory
+\texttt{texmf-var/luatex-cache/generic/names/} (\texttt{\$TEXMFCACHE} as set in
+\texttt{texmf.cnf}) of your \emph{TeX Live} distribution as a zlib-compressed
+file \texttt{luaotfload-names.lua.gz}.
+The experimental lookup cache will be created as
+\texttt{luaotfload-lookup-cache.lua} in the same directory.
+These Lua tables are not used directly by Luaotfload, though.
+Instead, they are compiled to Lua bytecode which is written to
+corresponding files with the extension \texttt{.luc} in the same directory.
+When modifying the files by hand keep in mind that only if the bytecode
+files are missing will Luaotfload use the plain version instead.
+Both kinds of files are safe to delete, at the cost of regenerating
+them with the next run of \emph{LuaTeX}.

+SYNOPSIS
+=======================================================================
+
+- **./luaotfload{.conf,rc}**
+- **XDG_CONFIG_HOME/luaotfload/luaotfload{.conf,rc}**
+- **~/.luaotfloadrc**
+
+DESCRIPTION
+=======================================================================
+
+The file ``luaotfload.conf`` contains configuration options for
+*Luaotfload*, a font loading and font management component for LuaTeX.
+
+
+EXAMPLE
+=======================================================================
+
+A small Luaotfload configuration file with few customizations could
+look as follows: ::
+
+ [db]
+ formats = afm,ttf
+ compress = false
+
+ [misc]
+ termwidth = 60
+
+ [run]
+ log-level = 6
+
+This will make Luaotfload ignore all font files except for PostScript
+binary fonts with a matching AFM file, and Truetype fonts. Also, an
+uncompressed index file will be dumped which is going to be much larger
+than the default gzip’ed index. The terminal width
+is truncated to 60 characters which influences the verbose output
+during indexing. Finally, the verbosity is increased greatly: each font
+file being processed will be printed to the stdout on a separate line,
+along with lots of other information.
+
+To observe the difference in behavior, save above snippet to
+``./luaotfload.conf`` and update the font index: ::
+
+ luaotfload-tool --update --force
+
+The current configuration can be written to disk using
+**luaotfload-tool**: ::
+
+ luaotfload-tool --dumpconf > luaotfload.conf
+
+The result can itself be used as a configuration file.
+
+
+SYNTAX
+=======================================================================
+
+The configuration file syntax follows the common INI format. For a more
+detailed description please refer to the section “CONFIGURATION FILE”
+of **git-config**\(1). A brief list of rules is given below:
+
+ * Blank lines and lines starting with a semicolon (``;``) are ignored.
+
+ * A configuration file is partitioned into sections that are declared
+ by specifying the section title in brackets on a separate line: ::
+
+ [some-section]
+ ... section content ...
+
+ * Sections consist of one or more variable assignments of the form
+ ``variable-name = value`` E. g.::
+
+ [foo]
+ bar = baz
+ quux = xyzzy
+ ...
+
+ * Section and variable names may contain only uppercase and lowercase
+ letters as well as dashes (``-``).
+
+
+VARIABLES
+=======================================================================
+
+Variables in belong into a configuration section and their values must
+be of a certain type. Some of them have further constraints. For
+example, the “color callback” must be a string of one of the values
+``post_linebreak_filter``, ``pre_linebreak_filter``, or
+``pre_output_filter``, defined in the section *run* of the
+configuration file.
+
+Currently, the configuration is organized into four sections:
+
+db
+ Options relating to the font index.
+
+misc
+ Options without a clearly defined category.
+
+paths
+ Path and file name settings.
+
+run
+ Options controlling runtime behavior of Luaotfload.
+
+The list of valid variables, the sections they are part of and their
+type is given below. Types represent Lua types that the values must be
+convertible to; they are abbreviated as follows: ``s`` for the *string*
+type, ``n`` for *number*, ``b`` for *boolean*. A value of ``nil`` means
+the variable is unset.
+
+
+Section ``db``
+-----------------------------------------------------------------------
+
++--------------------+--------+---------------------------+
+| variable | type | default |
++--------------------+--------+---------------------------+
+| compress | b | ``true`` |
++--------------------+--------+---------------------------+
+| designsize-dimen | b | ``bp`` |
++--------------------+--------+---------------------------+
+| formats | s | ``"otf,ttf,ttc"`` |
++--------------------+--------+---------------------------+
+| max-fonts | n | ``2^51`` |
++--------------------+--------+---------------------------+
+| scan-local | b | ``false`` |
++--------------------+--------+---------------------------+
+| skip-read | b | ``false`` |
++--------------------+--------+---------------------------+
+| strip | b | ``true`` |
++--------------------+--------+---------------------------+
+| update-live | b | ``true`` |
++--------------------+--------+---------------------------+
+
+The flag ``compress`` determines whether the font index (usually
+``luaotfload-names.lua[.gz]`` will be stored in compressed forms.
+If unset it is equivalent of passing ``--no-compress`` to
+**luaotfload-tool**. Since the file is only created for convenience
+and has no effect on the runtime behavior of Luaotfload, the flag
+should remain set. Most editors come with zlib support anyways.
+
+The setting ``designsize-dimen`` applies when looking up fonts from
+families with design sizes. In Opentype, these are specified as
+“decipoints” where one decipoint equals ten DTP style “big points”.
+When indexing fonts these values are converted to ``sp``. In order to
+treat the values as though they were specified in TeX points or Didot
+points, set ``designsize-dimen`` to ``pt`` or ``dd``.
+
+The list of ``formats`` must be a comma separated sequence of strings
+containing one or more of these elements:
+
+* ``otf`` (OpenType format),
+* ``ttf`` and ``ttc`` (TrueType format),
+* ``afm`` (Adobe Font Metrics),
+
+It corresponds loosely to the ``--formats`` option to
+**luaotfload-tool**. Invalid or duplicate members are ignored; if the
+list does not contain any useful identifiers, the default list
+``"otf,ttf,ttc"`` will be used.
+
+The variable ``max-fonts`` determines after processing how many font
+files the font scanner will terminate the search. This is useful for
+debugging issues with the font index and has the same effect as the
+option ``--max-fonts`` to **luaotfload-tools**.
+
+The ``scan-local`` flag, if set, will incorporate the current working
+directory as a font search location. NB: This will potentially slow
+down document processing because a font index with local fonts will not
+be saved to disk, so these fonts will have to be re-indexed whenever
+the document is built.
+
+The ``skip-read`` flag is only useful for debugging: It makes
+Luaotfload skip reading fonts. The font information for rebuilding the
+index is taken from the presently existing one.
+
+Unsetting the ``strip`` flag prevents Luaotfload from removing data
+from the index that is only useful when processing font files. NB: this
+can increase the size of the index files significantly and has no
+effect on the runtime behavior.
+
+If ``update-live`` is set, Luaotfload will reload the database if it
+cannot find a requested font. Those who prefer to update manually using
+**luaotfload-tool** should unset this flag. This option does not affect
+rebuilds due to version mismatch.
+
+Section ``default-features``
+-----------------------------------------------------------------------
+
+By default Luaotfload enables ``node`` mode and picks the default font
+features that are prescribed in the OpenType standard. This behavior
+may be overridden in the ``default-features`` section. Global defaults
+that will be applied for all scripts can be set via the ``global``
+option, others by the script they are to be applied to. For example,
+a setting of ::
+
+ [default-features]
+ global = mode=base,color=0000FF
+ dflt = smcp,onum
+
+would force *base* mode, tint all fonts blue and activate small
+capitals and text figures globally. Features are specified as a comma
+separated list of variables or variable-value pairs. Variables without
+an explicit value are set to ``true``.
+
+
+Section ``misc``
+-----------------------------------------------------------------------
+
++---------------+--------+-------------------------+
+| variable | type | default |
++---------------+--------+-------------------------+
+| statistics | b | ``false`` |
++---------------+--------+-------------------------+
+| termwidth | n | ``nil`` |
++---------------+--------+-------------------------+
+| version | s | <Luaotfload version> |
++---------------+--------+-------------------------+
+
+With ``statistics`` enabled, extra statistics will be collected during
+index creation and appended to the index file. It may then be queried
+at the Lua end or inspected by reading the file itself.
+
+The value of ``termwidth``, if set, overrides the value retrieved by
+querying the properties of the terminal in which Luatex runs. This is
+useful if the engine runs with ``shell_escape`` disabled and the actual
+terminal dimensions cannot be retrieved.
+
+The value of ``version`` is derived from the version string hard-coded
+in the Luaotfload source. Override at your own risk.
+
+
+Section ``paths``
+-----------------------------------------------------------------------
+
++------------------+--------+------------------------------------+
+| variable | type | default |
++------------------+--------+------------------------------------+
+| cache-dir | s | ``"fonts"`` |
++------------------+--------+------------------------------------+
+| names-dir | s | ``"names"`` |
++------------------+--------+------------------------------------+
+| index-file | s | ``"luaotfload-names.lua"`` |
++------------------+--------+------------------------------------+
+| lookups-file | s | ``"luaotfload-lookup-cache.lua"`` |
++------------------+--------+------------------------------------+
+
+The paths ``cache-dir`` and ``names-dir`` determine the subdirectory
+inside the Luaotfload subtree of the ``luatex-cache`` directory where
+the font cache and the font index will be stored, respectively.
+
+Inside the index directory, the names of the index file and the font
+lookup cache will be derived from the respective values of
+``index-file`` and ``lookups-file``. This is the filename base for the
+bytecode compiled version as well as -- for the index -- the gzipped
+version.
+
+
+Section ``run``
+-----------------------------------------------------------------------
+
++------------------+--------+------------------------------+
+| variable | type | default |
++------------------+--------+------------------------------+
+| anon-sequence | s | ``"tex,path,name"`` |
++------------------+--------+------------------------------+
+| color-callback | s | ``"post_linebreak_filter"`` |
++------------------+--------+------------------------------+
+| definer | s | ``"patch"`` |
++------------------+--------+------------------------------+
+| log-level | n | ``0`` |
++------------------+--------+------------------------------+
+| resolver | s | ``"cached"`` |
++------------------+--------+------------------------------+
+| fontloader | s | ``"default"`` |
++------------------+--------+------------------------------+
+
+Unqualified font lookups are treated with the flexible “anonymous”
+mechanism. This involves a chain of lookups applied successively until
+the first one yields a match. By default, the lookup will first search
+for TFM fonts using the Kpathsea library. If this wasn’t successful, an
+attempt is made at interpreting the request as an absolute path (like
+the ``[/path/to/font/foo.ttf]`` syntax) or a file name
+(``file:foo.ttf``). Finally, the request is interpreted as a font name
+and retrieved from the index (``name:Foo Regular``). This behavior can
+be configured by specifying a list as the value to ``anon-sequence``.
+Available items are ``tex``, ``path``, ``name`` -- representing the
+lookups described above, respectively --, and ``file`` for searching a
+filename but not an absolute path. Also, ``my`` lookups are valid
+values but they should only be used from within TeX documents, because
+there is no means of customizing a ``my`` lookups on the command line.
+
+The ``color-callback`` option determines the stage at which fonts that
+defined with a ``color=xxyyzz`` feature will be colorized. By default
+this happens in a ``post_linebreak_filter`` but alternatively the
+``pre_linebreak_filter`` or ``pre_output_filter`` may be chosen, which
+is faster but might produce inconsistent output. The
+``pre_output_filter`` used to be the default in the 1.x series of
+Luaotfload, whilst later versions up to and including 2.5 hooked into
+the ``pre_linebreak_filter`` which naturally didn’t affect any glyphs
+inserting during hyphenation. Both are kept around as options to
+restore the previous behavior if necessary.
+
+The ``definer`` allows for switching the ``define_font`` callback.
+Apart from the default ``patch`` one may also choose the ``generic``
+one that comes with the vanilla fontloader. Beware that this might
+break tools like Fontspec that rely on the ``patch_font`` callback
+provided by Luaotfload to perform important corrections on font data.
+
+The fontloader backend can be selected by setting the value of
+``fontloader``. The most important choices are ``default``, which will
+load the dedicated Luaotfload fontloader, and ``reference``, the
+upstream package as shipped with Luaotfload. Other than those, a file
+name accessible via 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 kpathsea.
+
+The value of ``log-level`` sets the default verbosity of messages
+printed by Luaotfload. Only messages defined with a verbosity of less
+than or equal to the supplied value will be output on the terminal.
+At a log level of five Luaotfload can be very noisy. Also, printing too
+many messages will slow down the interpreter due to line buffering
+being disabled (see **setbuf**\(3)).
+
+The ``resolver`` setting allows choosing the font name resolution
+function: With the default value ``cached`` Luaotfload saves the result
+of a successful font name request to a cache file to speed up
+subsequent lookups. The alternative, ``normal`` circumvents the cache
+and resolves every request individually. (Since to the restructuring of
+the font name index in Luaotfload 2.4 the performance difference
+between the cached and uncached lookups should be marginal.)
+
+
+FILES
+=======================================================================
+
+Luaotfload only processes the first configuration file it encounters at
+one of the search locations. The file name may be either
+``luaotfload.conf`` or ``luaotfloadrc``, except for the dotfile in the
+user’s home directory which is expected at ``~/.luaotfloadrc``.
+
+Configuration files are located following a series of steps. The search
+terminates as soon as a suitable file is encountered. The sequence of
+locations that Luaotfload looks at is
+
+i. The current working directory of the LuaTeX process.
+ii. The subdirectory ``luaotfload/`` inside the XDG configuration
+ tree, e. g. ``/home/oenothea/config/luaotfload/``.
+iii. The dotfile.
+iv. The *TEXMF* (using kpathsea).
