% \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{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.
%
%    \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{acronym}|}|
%    \end{quote}
%    to access the acronym. It stands for ``full acronym'' and it
%    always prints the full name
%    and the acronym in brackets.
%
%    \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{\acp}
%    Works in the same way as \cmd{\ac}, but makes the short and/or
%    long forms into  English plurals by adding an `s'.
%
%    \DescribeMacro{\acfp}
%    Works in the same way as \cmd{\acf}, but makes the short and
%    long forms into  English plurals by adding an `s'.
%
%    \DescribeMacro{\acsp}
%    Works in the same way as \cmd{\acs}, but makes the short
%    form into an English plural by adding an `s'.
%
%    \DescribeMacro{\aclp}
%    Works in the same way as \cmd{\acl}, but makes the long form
%    into an English plural by adding an `s'.
%
%    \DescribeMacro{\acfi}
%    Prints the Full Name acronym (\cmd{\acl}) in italics and the abbreviated
%    form (\cmd{\acs}) in upshaped form.
%
%    \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.
%
%    Example: |\acl{lox}/\acl{lh2} (\acsu{lox}/\acsu{lh2})|
%
%    \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{\acs*}, \cmd{\acl*}, \cmd{\acf*}, \cmd{\acp*},
%    \cmd{\acsp*}, \cmd{\aclp*}, \cmd{\acfp*}, \cmd{\acfi*}, \cmd{\acsu*}
%    and \cmd{\aclu*}.
%
% \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 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}
%    \DescribeEnv{acronym}
%    With the |acronym| environment you define all the acronyms in
%    your document.
%
%    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''.
%
%    All acronym definitions, made by \cmd{\acro} or \cmd{\acrodef}
%    are added to the |.aux| file. Therefore they are available
%    from start-up in the next run.
%
%    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}
%
%    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}:
%    \begin{quote}
%    |\usepackage[printonlyused]{acronym}|
%    \end{quote}
%    In \texttt{printonlyused}-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}
%
%  \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 the 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}-faktor}|
%             \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})

%    \begin{macrocode}
%<*acronym>
%    \end{macrocode}
%
%
%    \subsection{Identification}
%
%    First we test that we got the right format and name the package.
%    \begin{macrocode}
\NeedsTeXFormat{LaTeX2e}[1999/12/01]
\ProvidesPackage{acronym}[2008/05/21
                          v1.31
                          Support for acronyms (Tobias Oetiker)]
\RequirePackage{suffix}
%    \end{macrocode}
%
%
%
% \subsection{Options}
%
%    \begin{macro}{\ifAC@footnote}
%    The option |footnote| leads to a redefinition of \cmd{\acf} and
%    \cmd{\acfp}, making the full name appear as a footnote.
%    \begin{macrocode}
\newif\ifAC@footnote
\AC@footnotefalse
%    \end{macrocode}
%    \begin{macrocode}
\DeclareOption{footnote}{\AC@footnotetrue}
%    \end{macrocode}
%    \end{macro}
%
%    \begin{macro}{\ifAC@nohyperlinks}
%    If hyperref is loaded, all acronyms will link to their glossary entry.
%    With the option |nohyperlinks| these links can be suppressed.
%    \begin{macrocode}
\newif\ifAC@nohyperlinks
\AC@nohyperlinksfalse
%    \end{macrocode}
%    \begin{macrocode}
\DeclareOption{nohyperlinks}{\AC@nohyperlinkstrue}
%    \end{macrocode}
%    \end{macro}
%
%
%    \begin{macro}{\ifAC@printonlyused}
%    We need a marker
%    which is set if the option |printonlyused| was used.
%    \begin{macrocode}
\newif\ifAC@printonlyused
\AC@printonlyusedfalse
%    \end{macrocode}
%    \begin{macrocode}
\DeclareOption{printonlyused}{\AC@printonlyusedtrue}
%    \end{macrocode}
%    \end{macro}
%
%    \begin{macro}{\ifAC@withpage}
%    A marker which tells us to print page numbers.
%    \begin{macrocode}
\newif\ifAC@withpage
\AC@withpagefalse
%    \end{macrocode}
%    \begin{macrocode}
\DeclareOption{withpage}{\AC@withpagetrue}
%    \end{macrocode}
%    \end{macro}
%
%    \begin{macro}{\ifAC@smaller}
%    The option |smaller| leads to a redefinition of \cmd{\acsfont}.
%    We want to make the acronym appear smaller. Since this should
%    be done in a context-sensitive way, we rely on the macro
%    \cmd{\textsmaller} provided by the |relsize| package.
%    As \cmd{\RequirePackage} cannot be used inside
%    \cmd{\DeclareOption}, we need a boolean variable.
%    \begin{macrocode}
\newif\ifAC@smaller
\AC@smallerfalse
\DeclareOption{smaller}{\AC@smallertrue}
%    \end{macrocode}
%    \end{macro}
%
%    \begin{macro}{\ifAC@dua}
%    The option |dua| stands for ``don't use acronyms''.
%    It leads to a redefinition of \cmd{\ac} and
%    \cmd{\acp}, making the full name appear all the time
%    and suppressing all acronyms but the explicity requested by
%    \cmd{\acf} or \cmd{\acfp}.
%    \begin{macrocode}
\newif\ifAC@dua
\AC@duafalse
\DeclareOption{dua}{\AC@duatrue}
%    \end{macrocode}
%    \end{macro}
%
%    \begin{macro}{\ifAC@nolist}
%    The option |nolist| stands for ``don't write the list of acronyms''.
%    \begin{macrocode}
\newif\ifAC@nolist
\AC@nolistfalse
\DeclareOption{nolist}{\AC@nolisttrue}
%    \end{macrocode}
%    \end{macro}
%
%    Now we process the options.
%    \begin{macrocode}
\ProcessOptions\relax

%
%
%    \subsection{Setup macros}
%
%    \begin{macro}{\acsfont}
%    \begin{macro}{\acffont}
%    \begin{macro}{\acfsfont}
%    The appearance of the output of the commands \cmd{\acs} and
%    \cmd{\acf} is partially controlled by \cmd{\acsfont},
%    \cmd{\acffont}, and \cmd{\acfsfont}. By default, they do nothing
%    except when the |smaller| option is loaded.
%
%    The option |smaller| leads to a redefinition of \cmd{\acsfont}.
%    We want to make the acronym appear smaller. Since this should
%    be done in a context-sensitive way, we rely on the macro
%    \cmd{\textsmaller} provided by the |relsize| package.

%    \subsection{Additional Helper macros}
%
%
%    We need a list of the used acronyms after the last \cmd{\acresetall}
%    (or since beginning), a token list is very useful for this purpose
%
%    \begin{macro}{AC@clearlist}
%    \begin{macrocode}
\newtoks\AC@clearlist
%    \end{macrocode}
%    \end{macro}

%    \end{macro}
%
%
%    \begin{macro}{\acresetall}
%    \begin{macro}{\AC@reset}
%    This macro resets the |ac@FN| - tag of each acronym, therefore |\ac|
%    will use FullName (FN) next time it is called
%    \begin{macrocode}
\newcommand*\acresetall{\the\AC@clearlist\AC@clearlist={}}

\newcommand*\AC@used{@<>@<>@}
%    \end{macrocode}
%    \end{macro}
%
%    \begin{macro}{\AC@populated}
%    An on/off flag to note if any acronyms were logged. This
%    is needed for the first run with |printonlyused| option,
%    because the acronym list are then empty, resulting in a
%    |"missing item"| error.
%
%    \begin{macrocode}

%    \end{macro}
%
%
%    \begin{macro}{\AC@logged}
%    \begin{macro}{\acronymused}
%    Log the usage by writing the \cmd{\acronymused}
%    to the |aux| file and
%    by reading it back again at the beginning of the
%    document (performed automatically by LaTeX).
%    This results in processing the document twice,
%    but it is needed anyway for the rest of the
%    package.
%
%    This methodology is needed when the list of
%    acronyms is in the front matter of the document.
%    \begin{macrocode}
\newcommand*{\AC@logged}[1]{%
   \acronymused{#1}% mark it as used in the current run too
   \@bsphack

%
% \subsection{Defining acronyms}
%
%    There are three commands that define acronyms:
%    \cmd{\newacro}, \cmd{\acrodef}, and \cmd{\acro}.
%    They are called with the following arguments:
%    \begin{quote}
%       |\acro{|\meta{acronym}|}[|\meta{short name}^^A
%         |]{|\meta{full name}|}|
%    \end{quote}
%    The mechanism used in this package is to make the
%    optional \meta{short name} identical to the \meta{acronym} when it
%    is empty (no optional argument), thereby only the second (optional) argument
%    is stored together with the \meta{full name}.
%
%    \begin{macro}{\newacro}
%    \begin{macro}{\AC@newacro}
%    The internal macro \cmd{\newacro} stores the
%    \meta{short name} and the \meta{full name} in the
%    command \fnacro.
%    \begin{macrocode}
\newcommand*\newacro[1]{%
  \@ifnextchar[{\AC@newacro{#1}}{\AC@newacro{#1}[\AC@temp]}}
%    \end{macrocode}
%    \begin{macrocode}
\newcommand\AC@newacro{}

   \expandafter\gdef\csname fn@#1\endcsname{{#2}{#3}}%
   }
%    \end{macrocode}
%    \end{macro}
%    \end{macro}
%
%    \begin{macro}{\acrodef}
%    \begin{macro}{\AC@acrodef}
%    The user command \cmd{\acrodef} calls \cmd{\newacro} and
%    writes it into the |.aux| file.
%    \begin{macrocode}
\newcommand*\acrodef[1]{%
  \@ifnextchar[{\AC@acrodef{#1}}{\AC@acrodef{#1}[\AC@temp]}}
%    \end{macrocode}

%    \end{macro}
%
%
%    \begin{environment}{AC@deflist}
%    In standard mode, the acronym - list is formatted with a description
%    environment. If an optional argument is passed to the acronym
%    environment, the list is formatted as a AC@deflist, which needs the
%    longest appearing acronym as parameter. If the option 'nolist' is selected
%    the enviroment is empty.
%    \begin{macrocode}

%    \end{environment}
%
%    \begin{environment}{acronym}
%    In the 'acronym' - environment, all acronyms are defined, and printed
%    if they have been used before, which is indicated by the acused-tag.
%
%    \begin{quote}
%      |\begin{acronym}|\\

% \subsection{Using acronyms}
%
%
%    \begin{macro}{\ifAC@starred}
%    Before the macros are defined, we need a boolean variable which will

%    \begin{macro}{\AC@get}
%    If the acronym is undefined, the internal macro \cmd{\AC@get}
%    warns the user by printing the name in bold with an exclamation
%    mark at the end.
%    If defined, \cmd{\AC@get} uses the same mechanism used by the LaTeX
%    kernel commands \cmd{\ref} and \cmd{\pageref} to return the short
%    \cmd{\AC@acs} and long forms \cmd{\AC@acl} of the acronym
