+%   \section{Einführung}
+%
+%   \Hologo{LuaTeX} bringt zahlreiche Verbesserungen für alle Gebiete des
+%   Satzes und der Programmierung mit \hologo{TeX} mit sich.  Diese
+%   Verbesserungen werden in Form von neuen primitiven Befehlen oder durch den
+%   eingebetteten Lua-Interpreter zur Verfügung gestellt, und normale
+%   \hologo{LaTeX}-Benutzer sollten sich nicht damit beschäftigen müssen, sie
+%   in \hologo{LaTeX2e} zu integrieren.  Aus diesem Grund ist eine Vielzahl von
+%   \hologo{LaTeX2e}-Paketen entstanden, um die Lücke zwischen existierenden
+%   Dokumenten und den neuen Möglichkeiten zu schließen.  Das Paket
+%   \thispackage beschäftigt sich mit den zusätzlichen Möglichkeiten für den
+%   Mathematiksatz.  Die wichtigste davon ist die Möglichkeit, Unicode und
+%   OpenType-Schriften zu benutzen, was durch \Robertson{}s
+%   \pkg{unicode-math}-Paket ermöglicht wird.  Allerdings gibt es ein paar
+%   Änderungen, die nicht in Bezug zu Unicode stehen: um diese kümmert sich das
+%   vorliegende Paket.  Während prinzipiell die meisten \hologo{TeX}-Dokumente,
+%   die zur Verwendung mit den althergebrachten Engines verfasst wurden, ohne
+%   Probleme auch mit \hologo{LuaTeX} funktionieren sollten, gibt es ein paar
+%   wenige inkompatible Änderungen, die die Aufmerksamkeit von Paketautoren
+%   einfordern.  Das \thispackage-Paket versucht, einige der Probleme zu lösen,
+%   die bei der Übertragung einiger vorhandener Makropakete nach
+%   \hologo{LuaLaTeX} festgestellt wurden.
+%
+%   Im Allgemeinen sollte man nur nach sorgfältiger Abwägung Patches für
+%   vorhandene Makropakete verfassen: das Patchen von Code durch jemand anderen
+%   als den ursprünglichen Autor macht den neuen Code von der Implementation
+%   der gepatchten Funktionalität abhänging, was dem Kapselungsprinzip
+%   widerspricht.  Dennoch ist diese Art der Programmierung mangels
+%   Alternativen zu einer akzeptierten Herangehensweise beim Implementieren
+%   neuer Funktionalität für \hologo{LaTeX} geworden.  Um die negativen
+%   Auswirkungen so gering wie möglich zu halten, verändert das
+%   \thispackage-Paket nur den \hologo{LaTeX2e}-Kern und einige wenige bekannte
+%   Pakete.  Generell sollte das vorliegende Paket als eine Zwischenlösung
+%   angesehen werden, die zu entfernen ist, sobald die mathematiksatzbezogenen
+%   Pakete aktualisiert wurden und korrekt unter \hologo{LuaTeX} funktionieren.
+%   Aufgrund seiner Natur ist es wahrscheinlich, dass dieses Paket Probleme
+%   verursacht; in diesen Fall benutze bitte den
+%   Bugtracker\footnote{\url{https://github.com/phst/lualatex-math/issues}}.

+%   \section{Interface}
+%
+%   The \thispackage package can be loaded with \cmd{\usepackage} or
+%   \cmd{\RequirePackage}, as usual.  It has no options and no public
+%   interface; the patching is always done when the package is loaded and
+%   cannot be controlled.  As a matter of course, the \thispackage package
+%   needs \hologo{LuaLaTeX} to function; it will produce error messages and
+%   refuse to load under other engines and formats.  The package depends on the

+%   the \pkg{unicode-math} package; the fixes provided here are valid for both
+%   Unicode and legacy math typesetting.
+%
+%   Currently patches for the \hologo{LaTeX2e} kernel and the \pkg{amsmath},

+%   \section{Schnittstelle}
+%
+%   Das \thispackage-Paket kann wie üblich mit Hilfe von |\usepackage| oder
+%   |\RequirePackage| geladen werden.  Es besitzt weder Optionen noch eine
+%   öffentliche Schnittstelle; der Patchprozess wird automatisch durchgeführt,
+%   sobald das Paket geladen wird.  Selbstverständlich funktioniert das
+%   \thispackage-Paket nur unter \hologo{LuaLaTeX}; für andere Engines oder
+%   Formate bricht das Laden mit einer Fehlermeldung ab.  Das Paket hängt von
+%   der \pkg{expl3}-Sammlung, dem \pkg{etoolbox}-Paket, der
+%   \pkg{luatexbase}-Sammlung und dem \pkg{filehook}-Paket ab.  Das
+%   \thispackage-Paket ist unabhängig vom \pkg{unicode-math}-Paket; die hier
+%   zur Verfügung gestellten Korrekturen sind sowohl für Unicode"~ als auch für
+%   herkömmlichen Mathematiksatz gültig.
+%
+%   Aktuell werden Patches für den \hologo{LaTeX2e}-Kern sowie für die Pakete
+%   \pkg{amsmath}, \pkg{amsopn}, \pkg{mathtools} und \pkg{icomma} angeboten.
+%   Es spielt keine Rolle, ob diese Pakete vor oder nach \thispackage geladen
+%   werden.  Sie sollten funktionieren wie erwartet (und idealerweise sollte
+%   überhaupt keine Änderung bemerkbar sein), aber falls du andere Pakete, die
+%   selbst Befehle überschreiben, die von dem vorliegenden Paket gepatcht
+%   werden, lädst, können Probleme auftreten, wie bei \hologo{LaTeX} üblich.
+%
+%   Eine für den Benutzer sichtbare Änderung besteht darin, dass der neue
+%   primitive Befehl \DescribeMacros{\mathstyle\luatexmathstyle}|\mathstyle|
+%   (in \hologo{LuaLaTeX} allgemein als |\luatexmathstyle| bekannt) in allen
+%   Fällen funktionieren sollte, nachdem \thispackage geladen wurde, unter der
+%   Bedingung, dass die High-Level-Makros
+%   \DescribeMacros{\frac\binom\genfrac}|\frac|, |\binom| und |\genfrac|
+%   benutzt werden.  Die bruchartigen primitiven \hologo{TeX}-Befehle wie
+%   |\over| oder |\atopwithdelims| und die Makros aus dem
+%   \hologo{plainTeX}-Format wie |\brack| oder |\choose| können nicht gepatcht
+%   werden und sollten allgemein vermieden werden.
