\maketitle

\begin{abstract}
  The \texttt{neoschool} class provides secondary school teachers with
  a comprehensive toolkit for creating educational documents (tests,
  course handouts, exercise sheets with answer keys, and more).
  To accommodate a wide range of needs, it offers fifty-eight built-in color themes, sixteen preconfigured profiles,
  extensive class options for layout and typography,
  specialized environments, dedicated commands, and various
  preformatted header styles for each type of document.
  It bundles dozens of commonly used LaTeX packages,
  which significantly reduces preamble clutter and helps avoid compatibility issues.
  Multilingual support is included for English, French, and German.

When compiling with \texttt{lualatex}, it makes \texttt{fontspec}, \texttt{luacas}, \texttt{lua-ul}, and \texttt{luacolor} available, and applies the \texttt{TeX Gyre Pagella} and \texttt{TeX Gyre Heros} fonts alongside \texttt{newpxmath}.
