+sesstime v1.0
+Copyright 2016-2017 Niklas Beisert
+
+sesstime is a LaTeX2e package to add timing marks to lecture notes
+in order to help managing the time available for presenting a given
+section of the document. It also provides tools to record and
+estimate the progress throughout the course.
+
+The package consists of the files
+
+ README readme file
+ sesstime.ins installation file
+ sesstime.dtx source file
+ sesstime.sty package file
+ stimsamp.tex sample latex file
+ stimsmp3.tex sample include file
+ stimsmp4.tex sample include file
+ sesstime.pdf manual
+
+The distribution consists of the files README, sesstime.ins and sesstime.dtx.
+
+Run "(pdf)latex sesstime.dtx" to compile the manual sesstime.pdf.
+
+Run "latex sesstime.ins" to create the package sesstime.sty
+and the sample stimsamp.tex with stimsmp3.tex and stimsmp4.tex.
+Copy the file sesstime.sty to an appropriate directory of your LaTeX
+distribution, e.g. texmf-root/tex/latex/sesstime.

+\section{Introduction}
+
+A crucial step in designing a lecture course is to estimate
+the time needed for presenting the individual topics and to
+arrange them such that the overall teaching goals can be achieved
+within a predetermined amount of time.
+This step requires a lot of experience and the information is typically lost
+when (parts of) the lecture notes are recycled by different lecturer.
+While it is very useful to have timing information available
+for a number of purposes,
+it also takes patience and dedication to
+set it up and to keep it up to date when
+the presented material is changed (added, removed or shuffled).
+
+This package offers an interface to store such timing information
+in the \LaTeX{} source. It also offers some tools
+to process the raw data and display them in compiled form.
+The goals and features of this package include the following:
+\begin{itemize}
+\item
+Store timing information in the \LaTeX{} source
+(as absolute or relative times).
+\item
+Show small timing marks in the margin of the text.
+\item
+Indicate where sessions begin and end in the \LaTeX{} source
+and display session information in the text margin.
+\item
+Show the total time needed to present a given block, chapter or session
+at its start.
+\item
+Generate a table of sessions to track and estimate the progress
+throughout the course.
+\item
+Show brief comments regarding presentation,
+e.g.\ to skip certain parts or to pay particular attention.
+\item
+Maintain timing information in updates as conveniently as possible.
+\item
+Automatically generate the subdivision of sessions
+(based on the timing information provided).
+\end{itemize}
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+\section{Usage}
+
+This section describes the structures, markup and mechanisms
+provided by the package and some hints how to structure and maintain
+the information within the document.
+A complete reference of commands
+and configuration options in given in section \ref{sec:commands}.
+
+To use the package \textsf{sesstime} add the command
+\begin{center}
+|\usepackage{sesstime}|
+\end{center}
+to the preamble of your \LaTeX{} document.
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+\subsection{Blocks}
+
+The basic timing information is entered in a unit called \emph{block}.
+It has the following generic structure:
+%
+\begin{center}
+\begin{tabular}{l}
+|\timingstart{15}|\\
+|abc|\\
+|def|\\
+|\timingsplit{30}|\\
+|ghi|\\
+|jkl|\\
+|\timingsplit{40}|\\
+|mno|\\
+|pqr|\\
+|\timingstop{1:00}|\\
+\end{tabular}
+\end{center}
+%
+The above timing information is provided as absolute times
+(in [hours:]minutes),
+such that the block begins at 15 minutes and ends at 1 hour.
+It thus takes 45 minutes in total to present this block.
+Furthermore, two intermediate times are specified at 15 minutes
+and 25 minutes into the block
+(albeit in the form of absolute times).
+The timing information for the block will be displayed as:
+\vspace{2ex}
+\begin{center}
+\vrule\begin{minipage}{3em}
+\printmark{\textbf{90}\rlap{\vphantom{$\Updownarrow$}}\kern1.2em%
+ \hrule 45\rlap{\kern0.4em$\Downarrow$\vphantom{$\Updownarrow$}}\kern1.2em}
+abc\\
+def\par
+\printmark{\raisebox{-1ex}{15\rlap{\kern0.4em$\Updownarrow$}}\kern1.2em}
+ghi\\
+jkl\par
+\printmark{\raisebox{-1ex}{25\rlap{\kern0.4em$\Updownarrow$}}\kern1.2em}
+mno\\
+pqr\par
+\printmark{45\rlap{\kern0.4em$\Uparrow$\vphantom{$\Updownarrow$}}%
+ \kern1.2em\hrule%
+ \textbf{135}\rlap{\vphantom{$\Updownarrow$}}\kern1.2em}
+\end{minipage}
+\end{center}
+\vspace{2ex}
+Note that the displayed times are always relative to the block beginning.
+The bold numbers show the overall time outside the block
+(assuming that this block starts at 90 minutes).
+Furthermore, note that two \LaTeX{} passes are
+needed to display all data correctly
+(as for labels).
+
+Alternatively, the information can be entered as
+relative times with respect to the previous timing command:
+%
+\begin{center}
+\begin{tabular}{l}
+|\timingstart*{0}|\\
+|...|\\
+|\timingsplit*{15}|\\
+|...|\\
+|\timingsplit*{10}|\\
+|...|\\
+|\timingstop*{20}|
+\end{tabular}
+\end{center}
+%
+This markup has the same effect as the above timing commands
+using absolute times.
+There are some benefits and shortcomings to the two modes
+of entering the information,
+and the choice is left to the user.
+Note that relative and absolute times can be mixed
+(one absolute reference point should be specified previously).
+
+Some remarks and considerations are in order
+for setting up timing blocks
+and maintaining them when changing the presented material:
+\begin{itemize}
+\item
+If the duration of some presented material is estimated,
+it makes sense to specify relative times.
+\item
+If the duration is determined by periodically
+noting the present time displayed on a clock,
+it makes sense to specify these absolute times directly.
+\item
+When absolute times are specified, the duration of a block
+is determined by the final |\timingstop| (only).
+Split times given by |\timingsplit|[|*|] do not change
+the overall length.
+In order to change the duration of a block
+when some presented material is added or removed,
+all subsequent absolute times have to be adjusted.
+Alternatively, additional time can be specified by:
+%
+\begin{center}
+|\timinglapse{5}|
+\end{center}
+%
+This command conveniently adds 5 minutes to the block
+without modifying the current absolute time.
+When using relative times throughout the block,
+this has the same effect as |\timingsplit*{5}|.
+\end{itemize}
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+\subsection{Chapters}
+
+The package provides an additional layer
+of structure called \emph{chapters}.
+A chapter combines several blocks in order to display
+the overall required time as well as relative times within the chapter.
+
+A chapter is enclosed by two commands
+%
+\begin{center}
+\begin{tabular}{l}
+|\timingchapter|\\
+|abc|\\
+|def|\\
+|ghi|\\
+|\timingchapterend|
+\end{tabular}
+\end{center}
+%
+Closing a chapter is optional,
+it will be closed automatically by starting any subsequent chapter.
+
+There are three uses to declaring chapters.
+The total time for presenting the chapter is computed and
+it is displayed at the start:
+%
+\vspace{2ex}
+\begin{center}
+\vrule\begin{minipage}{3em}
+\printmark{\textbf{180}\rlap{\kern0.4em$\star$}\kern1.2em}
+abc\\
+def\\
+ghi
+\end{minipage}
+\end{center}
+%
+Furthermore, the bold numbers shown in the above examples
+for blocks indicate the present time relative to the beginning of the chapter.
+Finally, one can also show the total time needed for any chapter
+anywhere within the document,
+e.g.\ for a customised table of contents
+or next to the chapter title in a customised form.
+
+It will be useful to match the chapters and blocks
+to certain structures in the document.
+For example, chapters could correspond to chapters or sections
+depending on which documentclass is used.
+If the |\include| mechanism of \LaTeX{} is used to structure the document
+into several files,
+it makes sense to use these units as chapters for timing purposes.
+Blocks would typically correspond to the next level of structure
+(sections or subsections, respectively)
+and split times could be inserted naturally
+at any finer levels of structure (subsubsections, paragraphs).
+
+Establishing some guidelines how to entering timing information
+will be useful because the package will then compute the total durations
+of these structures and display the times at their beginnings.
+
+For maintenance purposes, a typical block could last
+around 30 minutes to an hour and be split at no more than a handful instances;
+more split times will take more efforts in maintaining across updates.
+There is no practical limitation to the length of individual chapters
+as times are computed automatically;
+typically it would consist of a couple of blocks.
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+\subsection{Sessions}
+
+Chapters will normally not map one-to-one to the units of presentation
+(individual lectures) which we shall call \emph{sessions}.
+It may be useful to keep track or estimate
+where each session will start (or end).
+There are two mechanisms to specify sessions.
+The manual declaration takes the form:
+%
+\begin{center}
+\begin{tabular}{l}
+|\timingsession|\\
+|abc|\\
+|def|\\
+|ghi|\\
+|\timingsessionend|
+\end{tabular}
+\end{center}
+%
+Again, closing a session is optional,
+it will be closed automatically by starting any subsequent session.
+Alternatively, the subdivision of sessions can be automatically
+estimated by the command:
+%
+\begin{center}
+|\timingconfigure{autosession=|\textit{duration}|}|
+\end{center}
+%
+This declares the duration of a session to be \textit{duration} minutes.
+New sessions will be started automatically when the available time for the
+previous session has elapsed
+(as far as possible with the timing information provided).
+
+Sessions have two uses.
+The start of a session is indicated in the margin
+together with its duration:
+%
+\begin{center}
+\begin{minipage}{3em}
+\printremark{session 4\\(35 min)}
+abc\\
+def\\
+ghi
+\end{minipage}\vrule
+\end{center}
+%
+Furthermore, a list of sessions can be displayed by the command:
+%
+\begin{center}
+|\timinglistofsessions|
+\end{center}
+%
+The list of sessions can serve two purposes in planning a lecture course.
+First, it outlines the (approximate) overall schedule and
+allows one to find out conveniently whether
+there will be sufficiently many sessions to cover the intended material.
+Second, the preview can help coordinating the
+topics for exercises to accompany the course.
+
+Note that the automatic assignment of sessions
+relies on the timing information provided in the blocks.
+On the one hand, the latter should be sufficiently fine-grained
+so that the session breaks can be located accurately.
+On the other hand, it will not be worth the effort
+to establish too detailed information.
+Providing one timing mark for around
+one third of the duration of a session
+will produce reasonable results.
+In the case of coarse-grained information,
+new sessions will be triggered such that
+the overall schedule remains approximately valid.
+The session marks will then be displayed some time
+after the session is expected is start, and the
+time difference is displayed.
+
+Note also that the list of sessions
+and total times rely on information stored in the |.aux| files.
+In order to update the information, it may be necessary
+to compile the complete document (without |\includeonly| statements) twice.
+
+Finally, it may be useful to emphasise that
+session marks can also be displayed without providing timing information.
+In that case, the subdivision of session evidently
+cannot be generated automatically, but must be stored manually.
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+\subsection{Comments}
+
+Occasionally it is useful to write some brief comments or instructions
+in the margin of lecture notes.
+While there are native \LaTeX{} tools to do so,
+the package provides an integrated mechanism:
+%
+\begin{center}
+|\timingcomment{|\textit{comment}|}|
+\end{center}
+%
+Such comments can serve many purposes, such as:
+%
+\begin{itemize}
+\textwidth0.9\textwidth
+\printremark{skipped}
+\item
+`skipped': The following part is skipped in the presentation.\par
+\printremark{brief!}
+\item
+`brief!': Be brief! Do not waste time!\par
+\printremark{explain!}
+\item
+`explain!': Explain well! Take your time!\par
+\printremark{exercise}
+\item
+`exercise': Hint at an accompanying exercise.
+\item
+\ldots
+\end{itemize}
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+\subsection{Flags}
+\label{sec:flags}
+
+The package allows to specify flags to distinguish
+different versions of the document
+or to set it up for different purposes
+(e.g.\ a particular iteration of the lecture course
+or lecture notes vs.\ textbook):
+%
+\begin{center}
+|\timingconfigure{flags={|\textit{flags}|}}|
+\end{center}
+%
+Here \textit{flags} is a comma-separated list of user-defined flags.
+Please avoid special characters and spaces (spaces next to
+comma separators are presently not ignored).
+
+Most timing commands provided by the package
+accept an optional argument which can be
+|[if=|\textit{flag}|]| or |[not=|\textit{flag}|]|
+(or combinations of these separated by comma).
+These commands will be processed only if the specified condition(s) hold.
+For example, the commands
+\begin{center}
+\begin{tabular}{l}
+|\timingcomment[if=2017]{skip}|\\
+|\timinglapse[if=2017]{-10}|
+\end{tabular}
+\end{center}
+can be used to indicate that the following part of the text is skipped
+in the 2017 iteration of the lecture course,
+and 10 minutes are saved by this omission.
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+\subsection{Printing}
+
+Detailed timing information or comments may be intended for
+private purposes only,
+while these marks should be stripped in a public version of the document.
+The package supplies some global options to enable and disable
+the printing of timing marks.
+To turn off all marks, use the package option:
+%
+\begin{center}
+|\timingconfigure{print=false}|
+\end{center}
+%
+Also individual types of timing marks can be suppressed
+by similar package options,
+see section \ref{sec:packageoptions}.
+For a finer selection or suppression of comments,
+one could use an optional argument such as
+|[if=private]| (only in the private version)
+or |[not=public]| (only in the public version),
+see section \ref{sec:flags}.
+
+Please note that the package uses a simple
+mechanism to place timing marks and comments in the margin
+next to the current location. This mechanism
+requires \TeX{} to be in so-called vertical mode
+(loosely speaking the space between paragraphs);
+marks cannot be set in horizontal mode
+(text within the paragraphs).
+As timing marks are naturally placed between the paragraphs
+and to avoid complications, a paragraph is automatically broken
+when a timing mark is placed in horizontal mode.
+This has the effect of splitting the current paragraph in two
+or occasionally inserting some extra vertical space between paragraphs.
+Note that this applies only if timing marks are actually printed,
+otherwise the structure of paragraphs is left untouched.
+
+Relatedly, it makes no sense to place timing marks \emph{after}
+a (sub)paragraph command which enforces horizontal mode
+to stay on the same line as the (sub)paragraph title;
+place any marks before the (sub)paragraph command.
+Also place timing marks at your own risk
+within manually designed boxes or minipages
+and avoid using them in mathematical mode.
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+\subsection{Customisation}
+
+The package provides some default layout for the various
+pieces of information to be displayed. However, it makes
+sense to customise some of these.
+
+For example, one could provide a list of session dates
+and customise the session display
+by changing the commands |\timingprintsession|
+and/or |\timingsessionline|
+to show the time instead of the session number.
+See appendix \ref{sec:sample} for a sample implementation.
+
+Please refer to the command reference in section \ref{sec:commands}
+as well as the implementation in appendix \ref{sec:implementation}
+to find out about commands to be customised:
+Commands suitable for customisation are among
+the public ones (prefix |timing|)
+and they should not make reference
+to internal commands (prefix |sti@|).
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+\section{Command Reference}
+\label{sec:commands}
+
+This section describes the commands provided by the package \textit{sesstime}.
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+\subsection{Blocks}
+\label{sec:blocks}
+
+\DescribeMacro{\timingstart}
+\DescribeMacro{\timingsplit}
+\DescribeMacro{\timingstop}
+\DescribeMacro{\timingnext}
+Timing information is entered using the block commands:
+\begin{center}
+\begin{tabular}{l}
+|\timingstart[|\textit{cond}|]{|\textit{abstime}|}|\\
+|\timingsplit[|\textit{cond}|]{|\textit{abstime}|}|\\
+|\timingstop[|\textit{cond}|]{|\textit{abstime}|}|\\
+|\timingnext[|\textit{cond}|]{|\textit{abstime}|}|
+\end{tabular}
+\end{center}
+The optional argument \textit{cond}
+is a comma-separated list of options described in
+section \ref{sec:flagsref}.
+The argument \textit{abstime} represents the absolute time at this instant;
+it can be specified in minutes
+or in the format \textit{hour}|:|\textit{minutes}.
+The first three of the above commands
+start, split or stop a block, respectively.
+The last command stops a block and starts the next one at the same time.
+
+Each of these commands has an alternative form:
+\begin{center}
+\begin{tabular}{l}
+|\timingstart*[|\textit{cond}|]{|\textit{reltime}|}|\\
+|\timingsplit*[|\textit{cond}|]{|\textit{reltime}|}|\\
+|\timingstop*[|\textit{cond}|]{|\textit{reltime}|}|\\
+|\timingnext*[|\textit{cond}|]{|\textit{reltime}|}|
+\end{tabular}
+\end{center}
+Here the argument \textit{reltime} is a relative time (in minutes)
+based on the previous block command.
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+\medskip
+\noindent
+\DescribeMacro{\timinglapse}
+\DescribeMacro{\timinggauge}
+There are two further commands to tweak the timers in useful ways:
+%
+\begin{center}
+|\timinglapse[|\textit{cond}|]{|\textit{reltime}|}|
+\end{center}
+%
+This command lets all timers evolve by \textit{reltime} minutes
+while keeping the absolute time fixed.
+It can be used to add or remove time from a block
+which is otherwise specified by absolute times.
+Instead of adjusting all later times by the lapse,
+it suffices to insert this command between two
+absolute time commands.
+
+The other command implements the opposite effect:
+%
+\begin{center}
+|\timinggauge[|\textit{cond}|]{|\textit{abstime}|}|
+\end{center}
+%
+This command adjusts the current reference time to \textit{abstime}
+(specified as minutes or in the format \textit{hour}|:|\textit{minutes})
+without evolving any of the timers.
+This can be used if a block stretches over several sessions
+where the absolute time changes between sessions.
+Gauging the time allows one to enter absolute times
+as read off from a clock.
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+\medskip
+\noindent
+\DescribeMacro{\timingblocktotal}
+The total time of the current block (in minutes) can be obtained
+by the command:
+\begin{center}
+|\timingblocktotal|[|*|]|[|\textit{error}|]|
+\end{center}
+The duration is saved into the macro |\timingreturn|.
+The starred form returns the duration of the subsequent block
+instead of the current block.
+If the time cannot be determined the optional argument \textit{error}
+(default value `??') is returned.
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+\subsection{Chapters}
+\label{sec:chapters}
+
+\DescribeMacro{\timingchapter}
+\DescribeMacro{\timingchapterend}
+Chapters are started and ended by the commands:
+\begin{center}
+\begin{tabular}{l}
+|\timingchapter[|\textit{cond}|]|\\
+|\timingchapterend[|\textit{cond}|]|
+\end{tabular}
+\end{center}
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+\medskip
+\noindent
+\DescribeMacro{\timingchapterlabel}
+\DescribeMacro{\timingchaptertotal}
+The total duration of a chapter is determined by the commands:
+\begin{center}
+\begin{tabular}{l}
+|\timingchapterlabel{|\textit{label}|}|\\
+|\timingchaptertotal[|\textit{error}|]{|\textit{label}|}|\\
+|\timingchaptertotal*[|\textit{error}|]{|\textit{chapter}|}|
+\end{tabular}
+\end{center}
+The first one must be invoked within
+a chapter to assign the label \textit{label}.
+The second one saves the duration
+for the chapter labelled by \textit{label}
+into the macro |\timingreturn|.
+The third (starred) form selects the chapter by the number \textit{chapter}.
+If undetermined, the optional argument \textit{error} (default value `??')
+is returned.
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+\subsection{Sessions}
+\label{sec:sessions}
+
+\DescribeMacro{\timingsession}
+\DescribeMacro{\timingsessionend}
+Sessions are started and ended by the commands:
+%
+\begin{center}
+\begin{tabular}{l}
+|\timingsession[|\textit{cond}|]|\\
+|\timingsessionend[|\textit{cond}|]|
+\end{tabular}
+\end{center}
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+\medskip
+\noindent
+\DescribeMacro{\timinglistofsessions}
+The list of sessions is printed by the command:
+\begin{center}
+|\timinglistofsessions|
+\end{center}
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+\subsection{Comments}
+\label{sec:comments}
+
+\DescribeMacro{\timingcomment}
+A comment is displayed by the command:
+%
+\begin{center}
+|\timingsession[|\textit{cond}|]{|\textit{comment}|}|
+\end{center}
+%
+As space in the margin is typically very limited,
+it makes sense to be as concise as possible,
+e.g.\ use just a single word or two.
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+\subsection{Flags}
+\label{sec:flagsref}
+
+The optional argument \textit{cond} for most of the above commands
+is a comma-separated list to specify the conditions
+under which the command is to be processed:
+%
+\begin{itemize}
+\item |if=|\textit{flag} --
+Process command only if \textit{flag} is among the currently declared flags.
+\item |not=|\textit{flag} --
+Process command unless \textit{flag} is among the currently declared flags.
+\end{itemize}
+%
+Note that the conditionals are processed in the same order as specified.
+After the first one is evaluated, all subsequent ones
+change the status only if
+\textit{flag} is among the currently declared flags.
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+\medskip
+\noindent
+\DescribeMacro{\timingif}
+A command for optional processing is:
+%
+\begin{center}
+|\timingif[|\textit{cond}|]{|\textit{code}|}|
+\end{center}
+%
+The code \textit{code} is processed
+only if the conditions \textit{cond} are met.
+
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+\subsection{Package Options}
+\label{sec:packageoptions}
+
+\DescribeMacro{\timingconfigure}
+Options can be passed to the package by the commands:
+\begin{center}
+\begin{tabular}{rl}
+&|\usepackage[|\textit{opts}|]{sesstime}|
+\\
+or&|\PassOptionsToPackage{|\textit{opts}|}{sesstime}|
+\\
+or&|\timingconfigure[|\textit{cond}|]{|\textit{opts}|}|
+\end{tabular}
+\end{center}
+%
+|\PassOptionsToPackage| must be used before |\usepackage|;
+|\timingconfigure| must be used afterwards (for selected options).
+\textit{opts} is a comma-separated list of options.
+Below we provide a complete list of available options:
+%
+\begin{itemize}
+\item |print|[|=true|$\vert$|false|]
+(no value implies |true|, initially set to |true|) --
+Enable/disable printing all timing marks.
+
+\item |block|[|=true|$\vert$|false|]
+(no value implies |true|, initially set to |true|) --
+Enable/disable printing block marks.
+
+\item |chapter|[|=true|$\vert$|false|]
+(no value implies |true|, initially set to |true|) --
+Enable/disable printing chapter marks.
+
+\item |session|[|=true|$\vert$|false|]
+(no value implies |true|, initially set to |true|) --
+Enable/disable printing session marks.
+
+\item |comment|[|=true|$\vert$|false|]
+(no value implies |true|, initially set to |true|) --
+Enable/disable printing comments.
+
+\item |warning|[|=true|$\vert$|false|]
+(no value implies |true|, initially set to |true|) --
+Enable/disable printing warnings.
+
+\item |width=|\textit{dimen}
+(initially set to |1cm|) --
+Specify width of timing marks in both margins.
+
+\item |widthl=|\textit{dimen}
+(initially set to |1cm|) --
+Specify width of timing marks in the left margin
+which are typically related to blocks and chapters.
+
+\item |widthr=|\textit{dimen}
+(initially set to |1cm|) --
+Specify width of timing marks in the right margin
+which are typically related to sessions and comments.
+
+\item |autosession=|\textit{duration}
+(initially set to |0|) --
+Set duration of automatically determined sessions;
+|0| disables automatic determination.
+
+\item |flags=|\textit{flags}
+--
+Specify a comma-separated list of flags.
+Avoid spaces between flags.
+\end{itemize}
+%
+Note that one can specify conditional evaluation for
+the command |\timingconfigure| to, e.g.,
+conditionally turn on automatic determination of sessions.

+%
+% %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+% \paragraph{Preamble.}
+%
+% Standard document class:

+% %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+% \paragraph{Required Packages.}
+%
+% The package loads the package
+% \textsf{keyval}
+% if not yet present.
+% \textsf{keyval} is used for extended options processing:
+% \begin{macrocode}
+\RequirePackage{keyval}
+% \end{macrocode}

+% %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+% \paragraph{Flags.}
+%
+% The following code compares flags for a command
+% against a global list of flags for optional processing of the command.
+%
+% \begin{macro}{\sti at processflags}
+% \begin{macro}{\ifsti at flag}
+% Declare variables for processing.
+% |\sti at flags| stores the list of selected flags.
+% |\ifsti at flag| is set by |\sti at processflags|.
+% |\ifsti at flaginit| is used to detect the first specified key:
+% \begin{macrocode}
+\def\sti at flags{}
+\newif\ifsti at flag
+\newif\ifsti at flaginit
+% \end{macrocode}
+% Compare given flag to list of flags stored in |\sti at flags|;
+% set |\ifsti at flag| accordingly.
+% First key sets default to opposite of specified condition:
+% \begin{macrocode}
+\define at key{sti at flag}{if}{%
+ \ifsti at flaginit\else\sti at flagfalse\fi\sti at flaginittrue%
+ \def\sti at tmpa{#1}%

+% \end{macrocode}
+% \end{macro}
+
+% %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+% \paragraph{Internal Definitions.}
+%
+% The following definitions store package options.
+% The conditional |\ifsti at print|[|...|]
+% indicates whether timing marks (of particular kind) should be printed.
+% The dimensions |\sti at widthl| and |\sti at widthr| store
+% the width of timing marks on the left and right, respectively.
+% |sti at autosession| stores the duration of automatically generated sessions:
+% \begin{macrocode}
+\newif\ifsti at print\sti at printtrue
+\newif\ifsti at printblock\sti at printblocktrue
+\newif\ifsti at printsession\sti at printsessiontrue
