 While writing a cookery book, units and their format can be quite
 troublesome. This contains not only the question of how to print those
-units, but also the question of the conversion of units. A cookery book

 % \section{Introduction}
 %
 %
 % While writing on a cookery book I used -- for reasons whatsoever --
 % three different units for weight: kilogram (kg), gram (g) and
-% decagram (dag, or older: dkg). Later my mother told me that she doesn't like it if a
-% cookery book uses more than two different units (for weight in this case).  Happily
-% I hardly used Decagram and therefore  didn't have many problems
-% changing the units. But, well \dots\ I am using \LaTeX\ and changing
-% those units by hand seemed not very \LaTeX\-like, so I started
-% writing some code to convert units. I expanded the code, rewrote it
-% in \LaTeX3 (which is much more pleasant than \LaTeXe) and here it
-% is.
-%
-% \section{Important note}
-%
-% This package uses the \pkg{translator} package to be able to switch
-% between different languages (german, english and french by now). 
-% To do that \pkg{translator} has to know
-% which languages are used. The (I think) easiest way is to specify
-% used languages using the optional argument of the documentclass (you
-% can do this for both \pkg{babel} and \pkg{polyglossia}\footnote{I
-% know that \pkg{polyglossia} doesn't support the \pkg{babel}-way of
-% setting the language by optional argument, but it doesn't harm.}):

+%
+% \begin{description}
+%   \item[Language] I am now using the \pkg{translations} package
+%     and I hope it makes things easier. As such, declaring the used language
+%     through class options shouldn't be necessary anymore.
+%   \item[Phrases] This package now supports the usage of \enquote{phrases}
+%     (words used instead of certain integers) (which I think are called \enquote{counting
+%     measures} in english, but I am not sure).
+%   \item[\cCutext] If no translation is found for a specific language,
+%    \cCutext\ are replaced by \mycs{cunum} with a warning is given.
+%   \item[Commands] Currently, it seems that allowing \meta{label}
+%     to be set by arrow-brackets was not the best idea as it leads to problems
+%    if they are made active (e.g. \pkg{babel} and option \opt{spanish}). As such,
+%    |<| is not allowed as a \enquote{special-sign} anymore as this package
+%   tries to \enquote{fix} this idea (at least make it work). If any problems occur
+%   (for this specific case or in general) please feel free to contact me.

 %
-%^^A You may write or have a recipe for a specific number of persons
-%^^A (e.g. for 4), but you would like to have this recipe for another number
-%^^A (e.g. only for two). Using labels  you can write your recipes and change
-%^^A the number of persons they are for. There are also two commands helping:
-%
-%^^A To change your recipe \emph{from} a specific number of persons (e.g. 4)
-%^^A \emph{to} another number of persons (e.g. 3) the following commands will
-%^^A prove helpfull:
 %
 % What if you don't want to change units, but the amounts of the recipe because
 % you cook not for 4 persons, but for 2 and don't like to do the math? 
 % Simple, use the following commands:
 %
 % \begin{itemize}
-%   \item \mycs{culabel} \marg{label} \marg{number of persons}
-%   \item \mycs{curef} \marg{label}
+%   \item \mycs{culabel}\marg{label}\marg{number of persons}
+%   \item \mycs{curef}\marg{label}
 % \end{itemize}
 %
-%^^A The first one is the important one: With its help you can define a \meta{label}
-%^^A which tells this package that the recipe is originally for \meta{number of persons}
-%^^A persons. This \meta{label} is then available for the commands introduced in 
-%^^A \vref{sec:commands} to be used. 
 %
 % The first one is the important one: It defines a \meta{label} for a recipe

+% \section{Some Interesting options}
+% 
+% This package has some options which might be of interest and to highlight them, this section exists. All options can be
+% found in \cref{sec:options}.
+%
+%
+%
+%   \begin{cuinterest}{use-numerals, use-numerals-below, print-numerals} 
+%   As seen above, you can use the \emph{package}-option
+%   \opt{use-numerals} to print integers used by \cCutext{} below
+%   \opt{use-numerals-below} (13 by default)  by \pkg{fmtcount}.
+%   You can still decide if numerals should be printed or not with \opt{print-numerals}.
+%
+%   \begin{cunote}
+%     \opt{use-numerals} is a package option as it needs to load
+%     \pkg{fmtcount} which is not loaded by default. 
+%   \end{cunote}
+%
+% \end{cuinterest}
+%
+% \begin{cuinterest}{use-phrases}
+%   In (I presume) all languages there exist phrases for a given
+%   amount or a number of things (think it is called \enquote{counting measurement}).
+%   In German you may say instead of
+%   \enquote{12}: \enquote{ein Dutzend}. Using this option you can tell this
+%   package to replace predefined integers used in \mycs{cuam} 
+%   by phrases for the currently used language
+%   (to define new ones, see \cref{sec:phrases})
+%
+%   Using (for example) language \opt{ngerman} (or \opt{naustrian}, etc.) with
+%   package option \opt{use-phrases=true} gives:
+%   \begin{myde}
+%     \begin{cuexamplecode}
+%       \cusetup{use-phrases=true} @
+%       \cuam{12} \\
+%       \cuam{24} \\
+%       \cuam{12--24} \\
+%       \cuam{12--13} \\
+%       \cuam{18} \\
+%       \cuam{60} 
+%     \end{cuexamplecode}
+%   \end{myde}
+% This of course also works with the \emph{package}-option \opt{use-numerals}:
+%   \begin{myde}
+%     \cusetup{print-numerals=true} 
+%     \begin{cuexamplecode}
+%       \cusetup{use-phrases=true} @
+%       \cuam{12} \\
+%       \cuam{24} \\
+%       \cuam{12--24} \\
+%       \cuam{12--13} \\
+%       \cuam{18} \\
+%       \cuam{60} 
+%     \end{cuexamplecode}
+%   \end{myde}
+%
+%
+%   \begin{cunote}
+%     Currently only the lower-case variant for \opt{use-numerals} is
+%     supported. Furthermore this feature is only available for \mycs{cuam}.
+%   \end{cunote}

-% and therefore separated \enquote{Pinch} (pn) and \enquote{Messerspitze} (Msp.).
-% My biggest problems with the units given in \vref{tab:some-more-units} is 
-% that they  may only exist in one language (or country)
-% and therefore do not exist in another language (I think for example that 
-% knife point \enquote{Messerspitze} doesn't exist in english) so translating
-% them would be difficult. Therefore use units known to you and if there are 
-% unsupported units or languages feel free to write (see \vref{sec:bug-feed}
-% for more details).
-%^^A I did not include a separate key for \enquote{Prise} (pinch), but you can use
-%^^A \texttt{Msp} (Messerspitze) and modify it to fit your
-%^^A purpose\footnote{See \vref{sec:language}.}.

+% \begin{function}{\cudefinephrase}
+%   \begin{syntax}

+%   given in \mycs{cuam} is either this number or a \emph{multiple} of it.
+%
+%   If the behavior of checking for a multiple is not wanted, you can use the optional
