% \section{Introduction}
% When writing a paper on cellular mobile radio I started to use a
% lot of acronyms. This can be very disturbing for the reader,
% as he might not know all the used acronyms. To help the reader
% I kept a list of all the acronyms at the end of my paper.
%
% This package makes sure, that all acronyms used in the text are
% spelled out in full at least once.
%
% \section{The user interface}
% The package provides several commands and one environment
% for dealing with acronyms. Their appearance can be controlled by
% two package options and three macros.
%
% \subsection{Acronyms in the Text}
%
% \DescribeMacro{\ac}
% To enter an acronym inside the text, use the
% \begin{quote}
% |\ac[|\meta{linebreak penalty}|]{|\meta{acronym}|}|
% \end{quote}
% command. The first time you use an acronym, the full name of the
% acronym along with the acronym in brackets will be printed. If you
% specify the |footnote| option while loading the package, the full
% name of the acronym is printed as a footnote.
% The next time you access the acronym only the acronym will
% be printed.
%
% When an acronym is being used, for the first time (with the |footnote|
% option not specified), next to the end of the line, a line break between
% the full name of the acronym and the acronym in brackets can be
% encountered. The optional variable represents the penalty level of
% breaking the line at that place, taking integer values between 0 and 4.
% A higher number corresponds to a higher penalty.
%
% \DescribeMacro{\Ac}
% Works in the same way as \cmd{\ac}, but starts the long form with an
% upper case letter. Use case: when the acronym is used for the first
% time, at the beginning of a sentence.
%
% \DescribeMacro{\acresetall}
% The 'memory' of the macro \cmd{\ac} can be flushed by calling the macro
% \cmd{\acresetall}. Afterwards, \cmd{\ac} will print the full name of any
% acronym and the acronym in brackets the next time it is used.
%
% \DescribeMacro{\acf}
% If later in the text again the Full Name of the acronym should be
% printed, use the command
% \begin{quote}
% |\acf[|\meta{linebreak penalty}|]{|\meta{acronym}|}|
% \end{quote}
% to access the acronym. It stands for ``full acronym'' and it
% always prints the full name and the acronym in brackets.
%
% When an full acronym is being used next to the end of the line, a line
% break between the full name of the acronym and the acronym in brackets
% can be encountered. The optional variable represents the penalty level
% of breaking the line at that place, taking integer values between 0
% and 4. A higher number corresponds to a higher penalty.
%
% \DescribeMacro{\Acf}
% Works in the same way as \cmd{\acf}, but starts the long form with an
% upper case letter.
%
% \DescribeMacro{\acs}
% To get the short version of the acronym, use the command
% \begin{quote}
% |\acs{|\meta{acronym}|}|
% \end{quote}
%
% \DescribeMacro{\acl}
% Gives you the expanded acronym without even mentioning the
% acronym.
% \begin{quote}
% |\acl{|\meta{acronym}|}|
% \end{quote}
%
% \DescribeMacro{\Acl}
% Works in the same way as \cmd{\acl}, but starts with an upper case
% letter.
%
% \DescribeMacro{\acp}
% Works in the same way as \cmd{\ac}, but makes the short and/or
% long forms into plurals.
%
% \DescribeMacro{\Acp}
% Works in the same way as \cmd{\acp}, but starts the long form with an
% upper case letter.
%
% \DescribeMacro{\acfp}
% Works in the same way as \cmd{\acf}, but makes the short and
% long forms into plurals.
%
% \DescribeMacro{\Acfp}
% Works in the same way as \cmd{\acfp}, but starts the long form with an
% upper case letter.
%
% \DescribeMacro{\acsp}
% Works in the same way as \cmd{\acs}, but makes the short
% form into a plural.
%
% \DescribeMacro{\aclp}
% Works in the same way as \cmd{\acl}, but makes the long form
% into a plural.
%
% \DescribeMacro{\Aclp}
% Works in the same way as \cmd{\aclp}, but starts with an upper case
% letter.
%
% \DescribeMacro{\acfi}
% Works in the same way as \cmd{\acf}, but prints the Full Name acronym
% (\cmd{\acl}) in italics and the abbreviated form (\cmd{\acs}) in
% upshaped form.
%
% \DescribeMacro{\Acfi}
% Works in the same way as \cmd{\acfi}, but starts the long form with an
% upper case letter.
%
% \DescribeMacro{\acfip}
% Works in the same way as \cmd{\acfi}, but makes the short and long
% forms into plurals.
%
% \DescribeMacro{\Acfip}
% Works in the same way as \cmd{\acfip}, but starts the long form with
% an upper case letter.
%
% \DescribeMacro{\acused}
% Marks an acronym as used, as if it had been called with \cmd{\ac},
% but without printing anything. This means that in the future only the
% short form of the acronym will be printed.
%
% \DescribeMacro{\acsu}
% Prints the short form of the acronym and marks it as used.
%
% \DescribeMacro{\aclu}
% Prints the long form of the acronym and marks it as used.
%
% \DescribeMacro{\Aclu}
% Works in the same way as \cmd{\aclu}, but starts with an upper case
% letter.
%
% Example: |\acl{lox}/\acl{lh2} (\acsu{lox}/\acsu{lh2})|
%
% \DescribeMacro{\iac}
% Works in the same way as the \cmd{\ac} command but prefixes it with
% an appropriate indefinite article.
%
% \DescribeMacro{\Iac}
% Works in the same way as the \cmd{\ac} command but prefixes it with
% an appropriate upper case indefinite article.
%
% \DescribeMacro{\...*}
% The following commands do the same as their unstarred forms, except
% that the acronym will not be marked as used. If you work with the 'onlyused'
% option then macros which have only been used with starred commands will
% not show up.\\
% \cmd{\ac*}, \cmd{\Ac*}, \cmd{\acs*}, \cmd{\acl*}, \cmd{\Acl*}, \cmd{\acf*},
% \cmd{\Acf*}, \cmd{\acp*}, \cmd{\Acp*}, \cmd{\acsp*}, \cmd{\aclp*}, \cmd{\Aclp*},
% \cmd{\acfp*}, \cmd{\Acfp*}, \cmd{\acfi*}, \cmd{\Acfi*}, \cmd{\acfip*},
% \cmd{\Acfip*}, \cmd{\acsu*}, \cmd{\aclu*}, \cmd{\Aclu*}, \cmd{\iac*},
% and \cmd{\Iac*}.
%
% \subsection{Customization}
%
% The appearance of \cmd{\acs} and \cmd{\acf} can be configured
% in various ways. Of main importance are the package options:
% \begin{description}
% \item[\normalfont|footnote|]
% makes the full name of the acronym appear as a footnote.
% \item[\normalfont|smaller|]
% lets the acronyms appear a bit smaller than the surrounding
% text. This is in accord with typographic convention.
% The |relsize| package is required.
% \end{description}
%
% There are three lower-level macros controlling the output.
% Any acronym printed by \cmd{\acs} is formatted
% by \DescribeMacro{\acsfont}\cmd{\acsfont}. Similarly, unless the
% option |footnote| is specified, \DescribeMacro{\acffont}\cmd{\acffont}
% handles the output of \cmd{\acf}, where the included acronym
% goes through \DescribeMacro{\acfsfont}\cmd{\acfsfont} (and
% \cmd{\acsfont}).
% The plural and upper case forms are treated accordingly. Usually the
% three macros do nothing. To give an example, the option |smaller|
% makes \cmd{\acsfont} use the command \cmd{\textsmaller} from the
% |relsize| package:
% \begin{quote}
% |\renewcommand*{\acsfont}[1]{\textsmaller{#1}}|
% \end{quote}
%
% \subsection{Defining Acronyms}
% Acronyms can either defined from an environment specifically
% introduced for that purpose or by direct definitions.
%
% \DescribeEnv{acronym}
% The |acronym| environment allows one to define all the acronyms
% needed by a document at a single place and is self-documenting,
% since a table of acronyms is automatically produced.
%
% In the |acronym| environment, acronyms are defined with the
% \DescribeMacro{\acro} command:
% \begin{quote}
% |\acro{|\meta{acronym}|}[|\meta{short name}|]{|\meta{full name}|}|
% \end{quote}
% The first argument \meta{acronym} is the acronym string itself
% and is used in the commands of the previous section such as
% \cmd{\ac} or \cmd{\acl}, that print the different forms of the
% acronym.
%
% Because internal commands take \meta{acronym} for storing
% the different forms of the acronym, the \TeX\ code for the
% acronym is limited by \cmd{\csname}.
% If the acronym requires problematic or complicate \TeX\ stuff
% (font commands, \dots), then this code
% can be given in the optional argument \meta{short name}.
% The first argument \meta{acronym} is then a simpler string
% to identify the acronym.
% For example, an acronym for water can look like this:
% \begin{quote}
% |\acro{H2O}[$\mathrm{H_2O}$]{water}|
% \end{quote}
% Then |\acs{H2O}| gets ``$\mathrm{H_2O}$'' and
% |\acl{H2O}| prints ``water''.
%%
% Inside the |acronym| environment \DescribeMacro{\acroextra}
% additional information can be added to the list of acronyms
% with the \cmd{\acroextra} command that will not be included
% in the normal inline acronyms.
%
% \begin{quote}
% |\acroextra{|\meta{additional info}|}|
% \end{quote}
%
% \noindent
% for example:
%
% \begin{quote}
% |\acro{H2O}[$\mathrm{H_2O}$]|\\
% | {Dihydrogen Monoxide\acroextra{ (water)}}|\\[1ex]
% |\acro{NA}[\ensuremath{N_{\mathrm A}}]|\\
% | {Number of Avogadro\acroextra{ (See \S\protect\ref{A1})}}|
% \end{quote}
%
% \noindent
% Note that \cmd{\acroextra} must be inserted inside the
% \cmd{\acro} definition and that fragile commands must be
% protected. Be careful of unnecessary spaces.
%
% The standard format of the acronym list is a \cmd{\description}
% environment. If you pass an optional parameter to the |acronym|
% environment, the width of the acronym-column will be fitted to the
% width of the given parameter (which should be the longest acronym).
% For example, if \textit{HBCI} is the longest acronym used, the
% list should start with
% \begin{quote}
% |\begin{acronym}[HBCI]|
% \end{quote}
%
% \DescribeMacro{\aclabelfont}
% The short form of each acronym in the list is formatted using
% \cmd{\aclabelfont}, which typesets its arguments in bold font by
% default. It can be redefined to produce bold sans-serif labels, for
% example, with
% \begin{quote}
% |\renewcommand*{\aclabelfont}[1]{\textbf{\textsf{\acsfont{#1}}}}|
% \end{quote}
%
% In standard mode, the acronym-list will consist of all defined
% acronyms, regardless if the the acronym was used in the text
% before or not. This behavior can be changed by loading the
% package with the parameter \texttt{printonlyused} (used at least once) or
% \texttt{printonlyreused} (use more than once):
% \begin{quote}
% |\usepackage[printonlyused]{acronym}|
% \end{quote}
% In \texttt{printonly(re)used}-mode you can add to each acronym the
% the page number where it was first used by additionally specifying
% the option \texttt{withpage}.
% \begin{quote}
% |\usepackage[printonlyused,withpage]{acronym}|
% \end{quote}
%
% If one does not want an acronym list to be produced at all,
% acronyms can be defined directly thanks to the two commands
% \DescribeMacro{\newacro}%
% \DescribeMacro{\acrodef}%
% \begin{quote}
% |\newacro{|\meta{acronym}|}[|\meta{short name}|]{|\meta{full name}|}|\\
% |\acrodef{|\meta{acronym}|}[|\meta{short name}|]{|\meta{full name}|}|
% \end{quote}
% \noindent the difference between the two consisting in the fact
% that the latter makes the acronym definition stored in the |.aux|
% file. Therefore, the acronym becomes available from start-up in
% the next run.
%
% Note that all the acronym definitions made by \cmd{\acro} in the
% |acronym| environment are also similarly added to the |.aux|
% file.
%
% \subsubsection{Non standard indefinite articles}
%
% Sometimes the indefinite article of an acronym differs between its
% short form and its long form, for example ``a Federal Bureau of
% Investigation (FBI) agent'' and ``an FBI agent''. To deal with this,
% the package provides the following three commands
% \DescribeMacro{\newacroindefinite}
% \DescribeMacro{\acrodefindefinite}
% \DescribeMacro{\acroindefinite}
% \begin{quote}
% |\acroindefinite{|\meta{acronym}|}{|\meta{short indefinite article}|}{|%
% \meta{long indefinite article}|}|\\
% |\newacroindefinite{|\meta{acronym}|}{|\meta{short indefinite article}|}{|%
% \meta{long indefinite article}|}|\\
% |\acrodefindefinite{|\meta{acronym}|}{|\meta{short indefinite article}|}{|%
% \meta{long indefinite article}|}|\\
% \end{quote}
% \noindent that allow one to define indefinite articles. The \cmd{\acroindefinite}
% command is meant to be used in the |acronym| environment. The
% difference among the latter two is that \cmd{\acrodefindefinite} puts
% the acronym definition in the |.aux| file, so that the acronym
% exception is available at the next run from start-up.
%
% When using \cmd{\iac} and \cmd{\Iac} without first defining an
% article, the default article is ``a''.
%
% \subsubsection{Non standard and foreign plural forms}
%
% When the plural form of an acronym is required, the package
% typically obtains it as an English plural, by adding an `s'. This
% happens both for long and short forms. For instance, for an
% acronym defined as
% \begin{quote}
% |\newacro{IC}{Integrated Circuit}|
% \end{quote}
% \noindent the |\acsp{IC}| command produces ``ICs'', and the
% |\aclp{IC}| command produces ``Integrated Circuits''.
%
% Unfortunately, this is generally not suitable for typesetting in
% languages different from English, and at times it is not correct
% even for English. For instance consider the ``MP'' acronym,
% commonly used to refer to a ``Member of the Parlament''. Of
% course, its long form plural is not ``Member of the Parlaments'',
% but ``Members of the Parlament''. For the short form plural,
% ``MPs'' is anyway commonly accepted. The same happens with ``SOC
% (System on a Chip)'' or ``BUT (Block Under Test)''.
%
% In foreign languages, things can be even more complicated. For
% instance, in Italian, there are different rules for English
% acronyms used in Italian text and Italian acronyms used in
% Italian text. The former do not get a plural at all, neither for
% the long, nor for the short form as in ``Un paio di
% \emph{Integrated Circuit (IC)}''. The latter get a plural long
% form following the natural Italian rules for plurals, and a
% plural short form that can either be the same as the singular
% short form, or --- at times --- a form obtained by doubling those
% letter of the short form that correspond to words that get a
% plural in the long form. For instance: ``Nucleo Investigativo
% (NI)'' could take a plural as in ``Nuclei Investigativi (NNII)'',
% although in modern texts one is more likely to find ``Nuclei
% Investigativi (NI)''.
%
% To deal with all these different situations, the package (since
% version 1.35) has been enriched with the following three commands
% \DescribeMacro{\acroplural}
% \DescribeMacro{\newacroplural}
% \DescribeMacro{\acrodefplural}
% \begin{quote}
% |\acroplural{|\meta{acronym}|}[|\meta{short plural}|]{|%
% \meta{long plural}|}|\\
% |\newacroplural{|\meta{acronym}|}[|\meta{short plural}|]{|%
% \meta{long plural}|}|\\
% |\acrodefplural{|\meta{acronym}|}[|\meta{short plural}|]{|%
% \meta{long plural}|}|\\
% \end{quote}
% \noindent that allow one to define plural exceptions. The \cmd{\acroplural}
% command is meant to be used in the |acronym| environment. The
% difference among the latter two is that \cmd{\acrodefplural} puts
% the acronym definition in the |.aux| file, so that the acronym
% exception is available at the next run from start-up. When the
% optional short form is not provided, the acronym name plus an `s'
% is used.
%
% Plural exceptions are never reported in tables of acronyms.
%
%
% \subsection{Miscellaneous}
% \subsubsection{Sectioning and pdf marks}
% Acronyms are robust (since version 1.12) and can be used in
% sectional headers such as \cmd{\chapter}, \cmd{\section}, etc.,
% but please note the following:
% \begin{itemize}
% \item Do not use the general form (\cmd{\ac} or \cmd{\acp}) in
% sectional headers, because it will uses the full name the first time,
% that is in the table of contents, and the short form further on.
%
% \item The text of \meta{acronym} is used verbatim in bookmarks and
% not \meta{short name} for pdf\TeX\ with \texttt{hyperref}.
%
% \item When the long form of the acronym is used in sectional headers
% (for pdf\TeX\ with \texttt{hyperref}), it will end up in the pdf
% bookmarks. In that case it is good to hide unusual text such as
% math inside the \cmd{\texorpdfstring} defined by \texttt{hyperref},
% for example:
% \begin{quote}
% |\acro{Nx}[\ensuremath{N_{\chi}}]|\\
% | {\texorpdfstring{$\chi$}{X}-factor}|
% \end{quote}
% which will then give
% \begin{quote}\begin{tabbing}
% pdf bookmark:\quad\=|\acf{Nx}| $\rightarrow$ \textsf{X-factor (Nx)}\\
% text: \>|\acf{Nx}| $\rightarrow$ $\chi$-factor~($N_{\chi}$)
% \end{tabbing}\end{quote}
%
% \item For acronyms in sectional headers, the file must be \textsc{pdf}\LaTeX'ed
% 3 times before the bookmarks are correct.
%
%
% \item Acronyms in sectional headers together with the |footnote| option
% will not give reliable results, because it will end up in the running
% heads and table of contents. If you really need it, use the optional
% argument of the sectioning commands. For example:
% \begin{quote}
% |\chapter[The water \texorpdfstring{$\mathrm{H_2O}$}{H2O}) ...]|\\
% | {The \acf{H2O} ...}|
% \end{quote}
% \end{itemize}

\section{Intro}
In the early nineties, \acs{GSM} was deployed in many European
countries. \ac{GSM} offered for the first time international
roaming for mobile subscribers. The \acs{GSM}'s use of \ac{TDMA} as
its communication standard was debated at length. And every now
and then there are big discussion whether \ac{CDMA} should have
been chosen over \ac{TDMA}.
\section{Furthermore}
\acresetall
The reader could have forgotten all the nice acronyms, so we repeat the
meaning again.
If you want to know more about \acf{GSM}, \acf{TDMA}, \acf{CDMA}
and other acronyms, just read a book about mobile communication. Just
to mention it: There is another \ac{UA}, just for testing purposes!

\subsection{Some chemistry and physics}
\label{Chem}
\ac{NAD+} is a major electron acceptor in the oxidation
of fuel molecules. The reactive part of \ac{NAD+} is its nictinamide
ring, a pyridine derivate.
One mol consists of \acs{NA} atoms or molecules. There is a relation
between the constant of Boltzmann and the \acl{NA}:
\begin{equation}
k = R/\acs{NA}
\end{equation}
\acl{lox}/\acl{lh2} (\acsu{lox}/\acsu{lh2})
\Acp{LFVP} are processes in which the lepton number of the initial
and final states are different. An example for \iac{LFVP} is
neutrinoless double beta decay.
\subsection{Some testing fundamentals}
When testing \acp{IC}, one typically wants to identify functional
blocks to be tested separately. The latter are commonly indicated as
\acp{BUT}. To test a \ac{BUT} requires defining a testing strategy\dots{}
\Iac{IC} popped up unexpectedly.
