\begin{abstract}
  The \pkg{faktor} package provides a mechanism to produce fractions
  for mathematical factors.
  Its mechanism is, however, quite limited.
  Inspired by the
  \href{https://tex.stackexchange.com/}{Tex StackExchange}
  answer of user
  \href{https://tex.stackexchange.com/users/5764/werner}{Werner},
  that was given on
  \href{https://tex.stackexchange.com/questions/27591/extending-the-faktor-package}
  {https://tex.stackexchange.com/\allowbreak questions/\allowbreak 27591/extending-the-faktor-package}
  we provide a simple package that wraps (and slightly modifies)
  the given answer into a more general \cs{faktor} command.
\end{abstract}

\begin{function}{\faktor}
\begin{function}{\faktor*}
  \begin{syntax}
    \cs{faktor}*\oarg{shift enumerator}\marg{enumerator}\oarg{shift denominator}\marg{denominator}
  \end{syntax}
  Produces a fraction with tilted \enquote{$\diagup$} symbol and the corresponding
  \meta{enumerator} and \meta{denominator}.
  The  \enquote{$\diagup$} symbol is automatically scaled.

  The \meta{shift} parameters can be controlled to fine tune the vertical
  placement of \meta{enumerator} and \meta{denominator}.
  Their default values when not given are \texttt{0.5} and \texttt{-0.5},
  respectively.

  The \enquote{*} can be optionally given. This will make the \cs{faktor}
  behave like the old \cs{faktor} command from the \cs{faktor} package,
  that is, the \enquote{$\diagup$} won't scale.
\end{function}
\end{function}

\begin{function}{\cofaktor}
\begin{function}{\cofaktor*}
  \begin{syntax}
    \cs{faktor}*\oarg{shift denominator}\marg{denominator}\oarg{shift enumerator}\marg{enumerator}
  \end{syntax}
  Behaves the same as \cs{faktor}, but produces a \cs{cofaktor}.
\end{function}
