-%   \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}}.

-%
-%   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
-%   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}|\mathstyle|
-%   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.
