+The \hologo{LaTeX} default is separation via indentation the |parskip| option switches to separation via vertical space.
+\footnote{Although the |parskip| option is used for this document, it is recommended only for very few document types such as technical manuals or answers to referees.}
+
+\subsubsection{Deactivation}
+
+The \software{hep-paper} package loads few bigger packages which have a large impact on the document.
+The deactivation options prevent such adjustments.
+
+\DescribeMacro{defaults}
+The |defaults| option prevents the adjustment of the page geometry and the font size set by the document class.
+
+\DescribeMacro{title}
+The |title=false| option deactivates the title page adjustments.
+
+\DescribeMacro{bibliography}

+
+\subsubsection{Compatibility}
+
+The compatibility options activate the compatibility mode for certain classes and packages used for publications in high energy physics.
+They are mostly suitable combinations of options described in the previous section.
+If \software{hep-paper} is able to detect the presence of such a class or package, \ie if it is loaded before the \software{hep-paper} package, the compatibility mode is activated automatically.
+

+
+\DescribeMacro{pos}
+The |pos| option activates the \software{PoS} compatibility mode.
+
+\subsubsection{Reactivation}
+
+The \software{hep-paper} package deactivates unrecommended macros, which can be reactivated manually.
+
+\DescribeMacro{manualplacement}
+The |manualplacement| option reactivates manual float placement.

+\section{Macros and environments}
+
+\subsection{Title page}
+
+\DescribeMacro{\author}
+\DescribeMacro{\affiliation}
+\DescribeMacro{\email}
+In order to facilitate multiple authors with different affiliations the |authblk| package \cite{authblk} is loaded.
+The following lines add \eg two authors with different affiliations
+
+| \author[1]{Author one \email{Email one}}|\\
+| \affiliation[1]{Affiliation one}|\\
+| \author[2]{Author two \email{Email two}}|\\
+| \affiliation[1,2]{Affiliation two}|
+
+\DescribeMacro{\title}
+The \PDF meta information is set according to the |\title|\marg{text} and |\author| \marg{text} information.
+
+\DescribeMacro{\preprint}
+The |\preprint|\marg{numer} macro places a pre-print number in the upper right corner of the title page.
+
+\DescribeEnv{abstract}
+The |abstract| environment is adjusted to not start with an indentation.
+
+\subsection{Text}
+
+Hyphenation is provided by the |babel| package \cite{babel} and quotation commands are provided by the |csquotes| package \cite{csquotes} recommended by the |babel| package.
+\DescribeMacro{\enquote}
+\DescribeMacro{\MakeOuterQuote}
+The latter package provides the convenient macros |\enquote|\marg{text} and |\MakeOuterQuote{"}| allowing to leave the choice of quotation marks to \hologo{LaTeX} and use |"| instead of the pair |``| and |''|, respectively.
+
+\DescribeMacro{\eg}
+\DescribeMacro{\vs}
+The |foreign| package \cite{foreign} defines macros such as |\eg|, |\ie|, |\cf|, and |\vs| which are typeset as \eg, \ie, \cf, and \vs.
+
+\DescribeMacro{\no}
+The |\no|\marg{number} macro is typeset as \no{123}.
+
+\DescribeMacro{\software}
+The |\software|\oarg{version}\marg{name} macro is typeset as \software[\fileversion]{HEP-Paper}.
+
+\DescribeMacro{\online}
+The |\online|\marg{url}\marg{text} macro combines the features of the |\href|\marg{url} \marg{text} \cite{hyperref} and the |\url|\marg{text} \cite{url} macros, resulting in \eg \online{https://ctan.org/pkg/hep-paper}{ctan.org/pkg/hep-paper}.
+
+The |inlinelist| and |enumdescript| environments are defined using the |enumitem| package \cite{enumitem}.
+
+\DescribeMacro{inlinelist}
+\begin{columns}
+|The three main points are|

+
+\DescribeMacro{\textsc}
+A bold versions \textbf{\textsc{Small Caps}} and a sans serif version of \textsf{\textsc{Small Caps}} is provided, using the |sansmathfonts| package \cite{sansmathfonts}.
+
+\DescribeMacro{\underline}
+\DescribeMacro{\overline}
+The |\underline| macro is redefined to allow line-breaks using the |ulem| package \cite{ulem}.
+The |\overline| macro is extended to also \overline{overline} text outside of math environments.
+
+\DescribeMacro{\useparskip}
+\DescribeMacro{\useparindent}
+If the |parskip| option is activated the |\useparindent| macro switches back the usual parindent mode, while the |\useparskip| macro switches to the parskip mode.
+
+\subsubsection{References and footnotes}
+
+\DescribeMacro{\cref}
+References are extended with the |cleveref| package \cite{cleveref}, which allows to \eg just type |\cref|\marg{key}  in order to write \enquote{figure 1}.
+Furthermore, the |cleveref| package allows to reference multiple objects within one |\cref|\marg{key1,key2}.
+
+\DescribeMacro{\cite}
+Citations are adjusted to not start on a new line in order to avoid the repeated use of |~\cite|\marg{key}.
+
+\DescribeMacro{\ref}
+\DescribeMacro{\eqref}
+\DescribeMacro{\subref}
+References are also adjusted to not start on a new line and are redefined in order to handle multiple references at once.
+
+\DescribeMacro{\footnote}
+Footnotes are adjusted to swallow white space before the footnote mark and at the beginning of the footnote text.
+
+\subsubsection{Acronyms}
+
+\DescribeMacro{\acronym}
+\DescribeMacro{\shortacronym}
+\DescribeMacro{\longacronym}
+The |\acronym|\meta{*}\oarg{typeset abbreviation}\marg{abbreviation}\meta{*}\marg{definition}\oarg{plural\linebreak[4]definition} macro generates the singular |\|\meta{abbreviation} and plural |\|\meta{abbreviation}|s| macros.
+The first star prevents the addition of an \enquote{s} to the abbreviation plural.
+The second star restores the \hologo{TeX} default of swallowing subsequent white space.
+The long form is only shown at the first appearance of these macros, later appearances generate the abbreviation with a hyperlink to the long form.
+Capitalization at the beginning of paragraphs and sentences is ensured.
+The |\shortacronym| and |\longacronym| macros are drop-in replacements of the |\acronym| macro showing only the short or long form of their acronym.
+\DescribeMacro{\resetacronym}
+\DescribeMacro{\dummyacronym}
+The first use form of the acronym can be enforced by resetting the acronym counter with |\resetacronym|\marg{key}.
+If the acronym counter equals one at the end of the document the short form of the acronym is not introduced.
+Placing a |\dummyacronym|\marg{key} at the end of the document ensures that the short form is introduced.
+
+\subsection{Math}
+
+The |mathtools| \cite{mathtools} and |amssymb| \cite{amsfonts} packages are loaded.
+They in turn load the \hologo{AmSLaTeX} |amsmath| \cite{amsmath} and |amsfonts| \cite{amsfonts} packages.
+\DescribeMacro{\mathbf}
+Bold math, via |\mathbf| is improved by the |bm| package \cite{bm}, \ie ($ A  b  \Gamma \delta \mathbf A \mathbf b \mathbf \Gamma \mathbf \delta$).
+Macros switching to |bfseries| such as |\section|\marg{text} are ensured to also typeset math in bold.
+This may cause trouble if bold symbols carry an additional non-implicit meaning.
+\DescribeMacro{\text}
+The |\text|\marg{text} macro makes it possible to write text within math mode, \ie ($ \text A  \text b  \text \Gamma \text \delta \text{\textbf A} \text{\textbf b} \text{\textbf \Gamma} \text{\textbf \delta}$).
+The often used |\mathrm|\marg{text} and |{\rm|\meta{text}|}| macros are \emph{not} the correct tool for this purpose, as they switch to roman font shape.
+This behaviour conflicts \eg with the |sansserif| package option.
+\DescribeMacro{\mathsf}
+The math sans serif alphabet is redefined to be italic sans serif if the main text is serif and italic serif if the main text is sans serif, \ie ($\mathsf A \mathsf b \mathsf \Gamma \mathsf \delta \mathbf{\mathsf A} \mathbf{\mathsf b} \mathbf{\mathsf \Gamma} \mathbf{\mathsf \delta}$).
+\DescribeMacro{\mathscr}
+The |\mathcal| font \ie ($\mathcal{ABCD}$) is accompanied by the |\mathscr| font \ie ($\mathscr{ABCD}$).
+\DescribeMacro{\mathbb}
+The |\mathbb| font is improved by the |doublestroke| package \cite{dsfont} and adjusted depending on the |sansserif| option \ie ($\mathbb{Ah1}$).
+\DescribeMacro{\mathfrak}
+Finally, the |\mathfrak| font is also available \ie ($\mathfrak{AaBb12}$).
+Details about the font handling in \hologo{TeX} can be found in \ccite{fntguide}.
+
+\DescribeMacro{\nicefrac}
+\DescribeMacro{\flatfrac}
+The |\frac|\marg{number}\marg{number} macro is accompanied by |\nicefrac|\linebreak[1]\marg{number}\linebreak[1]\marg{number} and |\flatfrac|\marg{number}\marg{number} leading to $\frac12$, $\nicefrac 12$, and $\flatfrac 12$.
+\DescribeMacro{\diag}
+\DescribeMacro{\sgn}
+Diagonal matrix |\diag| and signum |\sgn| operators are defined.
+
+\DescribeMacro{\mathdef}
+The |\mathdef|\marg{name}\oarg{arguments}\marg{code} macro (re-)defines macros only within math mode without changing the text mode definition.
+
+\DescribeMacro{\i}
+\DescribeMacro{\d}
+The imaginary unit $\i$ and the differential $\d$ are defined using this functionality.
+
+\DescribeMacro{\numberwithin}
+For longer paper it can be useful to re-number the equation in accordance with the section numbering |\numberwithin{equation}{section}|.
+\DescribeMacro{subequations}
+In order to further reduce the size the of equation counter it can be useful to wrap |align| environments with multiple rows in a |subequations| environment.
+Both macros are provided by the |amsmath| package.
+
+\DescribeMacro{eqnarray}
+The depreciated |eqnarray| environment is undefined as long this behaviour is not prevented by the |eqnarray| package option.
+The |split|, |multline|, |align|, |multlined|, |aligned|, |alignedat|, and |cases| environments of the |amsmath| and |mathtools| packages should be used instead.
+
+\DescribeMacro{equation}

+\begin{columns}
+|\begin{equation}|
+
+| left = right \ .|
+
+|\end{equation}|

+\DescribeMacro{split}
+Use the |split| sub environment for equations in which multiple equal signs should be aligned.
+
+\begin{columns}
+|\begin{equation} \begin{split}|
+
+| left &= right 1 \\|
+
+| &= right 2 \ .|
+

+&= \framebox[7em]{right 2\strut} \ .
+\end{split}
+\end{equation}
+\end{columns}
+
+\DescribeMacro{align}
+Use the |align| environment for the vertical alignment and horizontal distribution of multiple equations.
+
+\begin{columns}
+|\begin{subequations}|
+|\begin{align}|
+
+| left &= right \ , &|
+| left &= right \ , \\|

+\end{align}
+\end{subequations}
+\end{columns}
+
+\DescribeMacro{aligned}
+Use the |aligned| environment within a |equation| environment if the aligned equations should be labeled with a single equation number.
+
+\DescribeMacro{multlined}
+Use the |multlined| environment if either |split| or |align| contain very long lines.
+
+\begin{columns}
+|\begin{equation} \begin{split}|
+
+| left &= right 1 \\ &=|
+| \begin{multlined}[t]|
+|  right 2 \\ + right 3 \ .|

+  \framebox[7em]{+ right 3\strut} \ .
+\end{multlined}
+\end{split}
+\end{equation}
+\end{columns}

+
+\begin{columns}
+|\begin{subequations}|
+|\begin{alignat}{2}|
+
+| left &= long right && \ , \\|

+= \framebox[2.5em]{ri.\ 3\strut}} & \ .
+\end{alignat}
+\end{subequations}
+\end{columns}
+
+As a rule of thumb if you have to use |\notag|, |\nonumber|, or perform manual spacing via |\quad| you are probably using the wrong environment.
+
+\subsubsection{Physics}
+
+Greek letters are adjusted to always be italic and upright in math and text mode, respectively, using the |fixmath| \cite{fixmath} and |alphabeta| \cite{alphabeta} packages.
+This allows differentiations like
+\begin{align}
+\sigma &= \unit[5]{fb} \ , & &\text{at \unit[5]{\sigma} C.L.} \ , & \mu &= \unit[5]{cm} \ , & l &= \text{\unit[5]{\mu m}} \ ,
+\label{eq:greek}
+\end{align}
+and \eg to distinguish gauge $\nu$ and mass \nu\ eigenstates in models with massive neutrinos.
+Additionally, Greek letters can also be directly typed using Unicode.
+
+\DescribeMacro{\ev}
+\DescribeMacro{\pdv}
+\DescribeMacro{\comm}
+\DescribeMacro{\order}
+The |physics| package \cite{physics} provides additional macros such as
+\begin{align}
+&\ev{\phi} \ ,
+&&\pdv[n]{f}{x} \ ,
+&&\comm{A}{B} \ ,
+&&\order{x^2} \ ,
+&&\eval{x}_0^\infty \ ,
+&&\det(M)\ .
+\end{align}
+
+\DescribeMacro{\cancel}
+\DescribeMacro{\slashed}
+The |\cancel|\marg{characters} macro from the |cancel| \cite{cancel} package and the |\slashed| \marg{character} macro from the |slashed| \cite{slashed} package allow to $\cancel{\text{cancel}}$ math and use the Dirac slash notation \ie $\slashed \partial$, respectively.
+
+\DescribeMacro{\overleftright}
+A better looking over left right arrow is defined \ie $\overleftright{\partial}$.
+
+\DescribeMacro{\unit}
+\DescribeMacro{\inv}
+The correct spacing for units, \cf \cref{eq:greek}, is provided by the macro |\unit|\oarg{value} \marg{unit} from the |units| package \cite{units} which can also be used in text mode.
+The macro |\inv|\oarg{power}\marg{text} allows to avoid math mode also for inverse units such as \unit[5]{\inv{fb}} typeset via |\unit[5]{\inv{fb}}|.
+
+\subsection{Floats}
+
+\DescribeEnv{figure}
+\DescribeEnv{table}
+Automatic float placement is adjusted to place a single float at the top of pages and to reduce the number of float pages, using the \hologo{LaTeX} macros.
+
+|\setcounter{bottomnumber}{0}| \hfill no floats at the bottom of a page (default 1) \\
+|\setcounter{topnumber}{1}| \hfill a single float at the top of a page (default 2) \\
+|\setcounter{dbltopnumber}{1}| \hfill same for full widths floats in two-column mode \\
+|\renewcommand{\textfraction}{.1}| \hfill large floats are allowed (default 0.2)\\
+|\renewcommand{\topfraction}{.9}| \hfill (default 0.7) \\
+|\renewcommand{\dbltopfraction}{.9}| \hfill (default 0.7) \\
+|\renewcommand{\floatpagefraction}{.8}| \hfill float pages must be full (default 0.5)
+
+Additionally, manual float placement is deactivated but can be reactivated using the |manualplacement| package option.
+It is however recommended to archive the desired design by adjusting above macros.
+The most useful float placement is usually archived by placing the float \emph{in front} of the paragraph it is referenced in first.
+\DescribeMacro{\raggedright}
+The float environments have been adjusted to center their content.
+The usual behaviour can be reactivated using |\raggedright|.

+} \label{tab:table}
+\end{table}
+
+\DescribeEnv{panels}
+\DescribeMacro{\panel}
+The |panels| environment makes use of the |subcaption| package \cite{subcaption}.
+It provides sub-floats and takes as mandatory argument either the number of sub-floats (default~2) or the width of the first sub-float as fraction of the |\linewidth|.
+Within the |\begin{panels}|\oarg{vertical alignment}\marg{width} environment the |\panel| macro initiates a new sub-float.
+In the case that the width of the first sub-float has been given as an optional argument to the |panels| environment the |\panel|\marg{width} macro takes the width of the next sub-float as mandatory argument.
+The example code is presented in \cref{tab:panels}.
+
+\DescribeEnv{tabular}
+The |booktabs| \cite{booktabs} and |multirow| \cite{multirow} packages are loaded enabling publication quality tabulars such as in \cref{tab:booktabs}.
+
+\DescribeMacro{\graphic}
+\DescribeMacro{\graphics}
+The |graphicx| package \cite{graphicx} is loaded and the |\graphic|\oarg{width}\marg{figure} macro is defined, which is a wrapper for the |\includegraphics|\marg{figure} macro and takes the figure width as fraction of the |\linewidth| as optional argument (default~1).
+If the graphics are located in a sub-folder its path can be indicated by |\graphics|\marg{subfolder}.
+
+\subsection{Bibliography}
+
+\DescribeMacro{\bibliography}
+\DescribeMacro{\printbibliography}
+The |biblatex| package \cite{biblatex} is loaded for bibliography management.
+The user has to add the line |\bibliography|\marg{my.bib} to the preamble of the document and |\printbibliography| at the end of the document.
+The bibliography is generated by \software{Biber} \cite{biber}.
+|biblatex| is extended to be able to cope with the |collaboration| and |reportNumber| fields provided by \online{https://inspirehep.net}{inspirehep.net} and a bug in the volume number is fixed.
+Additionally, the PubMed IDs are recognized and \online{https://ctan.org}{ctan.org}, \online{https://github.com}{github.com}, \online{https://gitlab.com}{gitlab.com}, \online{https://bitbucket.org}{bitbucket.org}, \online{https://www.launchpad.net}{launchpad.net}, \online{https://sourceforge.net}{sourceforge.net}, and \online{https://hepforge.org}{hepforge.org} are valid |eprinttype|s.
+\DescribeMacro{erratum}
+Errata can be included using the |related| feature.
+
+| \article{|\meta{key1}|,|\\
+|   |\dots|,|\\
+|   relatedtype="erratum",|\\
+|   related="|\meta{key2}|",|\\
+| }|\\
+| \article{|\meta{key2}|,|\\

+
+\section{Conclusion}
+
+The |hep-paper| package provides a matching selection of preloaded packages and additional macros enabling the user to focus on the content instead of the layout by reducing the amount of manual tasks.
+The majority of the loaded packages are fairly lightweight, the others can be deactivated with package options.
+
+\DescribeMacro{arxiv-collector}
+\nolinkurl{arxiv.org} \cite{arxiv} requires the setup dependent |bbl| files instead of the original |bib| files, which causes trouble if the local \hologo{LaTeX} version differs from the one used by arXiv.
+The |arxiv-collector| python script \cite{arxiv-collector} alleviates this problem by collecting all files necessary for publication on arXiv (including figures).

-% \subsubsection{References and footnotes}
-%
-% \DescribeMacro{\cref}
-% References are extended with the |cleveref| package \cite{cleveref}, which allows to \eg just type |\cref|\marg{key}  in order to write \enquote{Figure 1}.
-% Furthermore, the |cleveref| package allows to reference multiple objects within one |\cref|\marg{key1,key2}.
-%
-% \DescribeMacro{\cite}
-% Citations are adjusted to not start on a new line in order to avoid the repeated use of |~\cite|\marg{key}.
-%

-% \DescribeMacro{\eqref}
-% \DescribeMacro{\subref}
-% References are also adjusted to not start on a new line and are redefined in order to handle multiple references at once.
-%
-% \DescribeMacro{\footnote}

-%
-% \subsubsection{Acronyms}
-%
-% \DescribeMacro{\acronym}
-% \DescribeMacro{\shortacronym}
-% \DescribeMacro{\longacronym}
-% The |\acronym|\meta{*}\oarg{typeset abbreviation}\marg{abbreviation}\meta{*}\marg{definition}\oarg{plural\linebreak[4]definition} macro generates the singluar |\|\meta{abbreviation} and plural |\|\meta{abbreviation}|s| macros.
-% % The first star prevents the addition of an \enquote{s} to the abbreviation plural.
-% The second star restores the \hologo{TeX} default of swallowing subsequent white space.
-% The long form is only shown at the first appearance of these macros, later appearances generate the abbreviation with a hyperlink to the long form.
-% Capitalization at the beginning of paragraphs and sentences is ensured.
-% The |\shortacronym| and |\longacronym| macros only show the short or long form of their acronym.
-% \DescribeMacro{\resetacronym}
-% \DescribeMacro{\dummyacronym}
-% The first use form of the acronym can be enforced by resetting the acronym counter.
-% If the acronym counter equals one at the end of the document the short form of the acronym is not introduced.
-% Placing a |\dummyacronym|\marg{key} at the end of the document ensures that the short form is introduced.
-%
-% \subsection{Math}
-%
-% The |mathtools| \cite{mathtools} and |amssymb| \cite{amsfonts} packages are loaded.
-% They in turn load the \hologo{AmSLaTeX} |amsmath| \cite{amsmath} and |amsfonts| \cite{amsfonts} packages.
-% Details about the font handling in \hologo{TeX} can be found in \cite{fntguide}.
-% \DescribeMacro{\mathbf}
-% Bold math, including |\mathbf| is provided by the |bm| package \cite{bm}, \ie ($ A  b  \Gamma \delta \mathbf A \mathbf b \mathbf \Gamma \mathbf \delta$).
-% Macros switching to |bfseries| such as |\section|\marg{text} are ensured to also typeset math in bold.
-% This may cause trouble if bold symbols carry an additional non-implicit meaning.
-% \DescribeMacro{\text}
-% The |\text|\marg{text} macro makes it possible to write text within math mode, \ie ($ \text A  \text b  \text \Gamma \text \delta \text{\textbf A} \text{\textbf b} \text{\textbf \Gamma} \text{\textbf \delta}$).
-% The often used |\mathrm|\marg{text} and |\rm|\marg{text} macros are \emph{not} the correct tool for this purpose, as they switch to roman font shape.
-% This behaviour conflicts \eg with the |sansserif| package option.
-% \DescribeMacro{\mathsf}
-% The math sans serif alphabet is redefined to be italic sans serif if the main text is serif and italic serif if the main text is sans serif, \ie ($\mathsf A \mathsf b \mathsf \Gamma \mathsf \delta \mathbf{\mathsf A} \mathbf{\mathsf b} \mathbf{\mathsf \Gamma} \mathbf{\mathsf \delta}$).
-% \DescribeMacro{\mathscr}
-% The |\mathcal| font \ie ($\mathcal{ABCD}$) is accompanied by the |\mathscr| font \ie ($\mathscr{ABCD}$).
-% \DescribeMacro{\mathbb}
