+% \thispagestyle{empty}
+%\begin{abstract}
+% This class is designed to typeset laboratory journals with \LaTeX\
+% that contain chronologically ordered records about experiments. Each
+% day, the new pages are simply added at the end, and from the
+% sectioning commands, an experiment index is generated to make it
+% easier to find a particular experiment. Because |\frontmatter| has
+% roman page numbering, it is easy to separately extend index, toc and
+% list of abbreviations. The class is based on the KOMA-Script class
+% |scrbook.cls|. Therefore all features of this class can be used --
+% reading of |scrguide| (german) or |scrguien| (english), the
+% documentation of KOMA-Script, is highly recommended.

+% \section{General information}
+%
+%
+% \subsection{Legal considerations}
+%
+% Writing of laboratory journals is sometimes regulated by law,
+% often funding institutions have additional requirements. Thus it is
+% usually \emph{not} allowed to keep a lab journal in electronic form
+% only; sometimes even hardcover books have to be used. On the other
+% hand it seems to be common practice to keep notes on loose leafes,
+% computer files or a jotter book and compile them in the hardcover
+% lab journal in a more or less regular manner.
+%
+% Therefore it seems tenable to work with an electronic version of the
+% journal and a printout in parallel. If required, the printout can be
+% clipped or bound, and a version on a CD-ROM should have equal
+% value as evidence as a book. On the other hand, one gains a lot,
+% especially with a PDF version: full text search, easy inclusion of
+% graphs and pictures, possibility of hyperlinking to data files etc.
+%
+% \subsection{Features}
+% \label{sec:features}
+%
+% \begin{description}
+% \item[basis class] |labbook.cls| is based on the KOMA-Script-class
+% |scrbook.cls|. Therefore it offers all the features of this class:
+% changing the page layout, head- and footlines, paragraph markup, and
+% changing appearance of floats and margin notes. It is highly
+% recommended to read the documentation, scrguien.
+% \item[Sectioning] The lab journal is structured in a chronological
+% way. Instead of |\chapter|, |\labday| is used. Within a day the
+% text is sectioned according to experiments -- this can be a
+% complete measurement from design to evaluation, but also one test
+% in a series that takes several days. |\experiment| is on the level
+% of section, and there is |\subexperiment| which corresponds to
+% |\subsection|. Below that, the usual sectioning commands can be
+% used (although their usage doesn't seem very sensible to me,
+% mind KOMA-script's |\minisec| command).
+% \item[Index and table of contents] Because of the chronological
+% structure, a traditional table of contents is not sufficient,
+% especially if investigations in a series of experiments are
+% conducted on different days. Therefore, an index is created. It is
+% built from the toc entries of the sectioning commands. One can
+% also define abbreviations to use in the argument of |\experiment|
+% and |\subexperiment|. Thus, the consistent creation of the index
+% is much easier. Furthermore, you can create multiple index
+% entries for one experiment.
+% \item[hyperref integration] The class works together well with
+% |hyperref.sty| to produce PDF files with navigation features.
+% \end{description}
+%
+% \section{Usage}
+% \label{sec:usage}
+%
+%
+% \subsection{Initialization}
+% \label{sec:options}
+%
+% If you want to use hyperref.sty, you \emph{must} specify the class
+% option |hyperref| like this
+% \begin{verbatim}\documentclass[hyperref]{labbook}\end{verbatim}
+% after that you can load hyperref and other packages
+% in the order appropriate for your document. If you load hyperref.sty
+% without giving the option, hyperref will overwrite some changes this
+% class makes to \LaTeX\ internals. If you use hyperref, you should
+% also consider the KOMA option |idxtotoc|: The index will not only be
+% listed in the table of contents, but also in the PDF bookmarks.
+%
+% Besides that, all options you specifiy are just handed on to
+% |scrbook.cls|. You might want to use |openany| to allow new labdays
+% to begin on any page.
+%
+% \section{Sectioning commands}
+% \label{sec:gliederungsbefehle}
+%
+%\subsection{\textbackslash\texttt{labday}}
+%\label{sec:labday}
+%
+% \DescribeMacro{\labday}
+% |labday| can be used to create an unnumbered heading formatted like a
+% chapter. Its text is put into the table of contents and used as
+% running title -- usually one would just use the date, perhaps with the
+% weekday. It should be used only within mainmatter and will take care
+% of index entries for the lower sectioning levels (see below). It calls
+% |\addchap| internally, there is no starred form or optional argument
+% to |\labday|.
+%
+% \subsection{\textbackslash\texttt{experiment} and
+% \textbackslash\texttt{subexperiment}: The simple usage}
+% \label{sec:exper-und-subexp}
+%
+% \DescribeMacro{\experiment}
+% Within a |\labday|, numbered headlines for
+% single experiments can be created with
+% \begin{verbatim}\experiment[<short form>]{long form}\end{verbatim}
+% Its text (or that of the optional argument) is not only typeset in the
+% table of contents and page head, but also in the index. This eases the
+% orientation, particularly if experiments are done several times or
+% take longer than one day. The index entries specify the page range of
+% the whole experiment, not only the starting page; and if the same
+% experiment is repeated on different days that fall on subsequent
+% pages, one common index range is generated.
+%
+% Note that you cannot use commas\footnote{In fact, the string
+% \texttt{\MVAt--\MVAt} is not allowed, too -- see the implementation
+% notes below.} in the optional argument (see below). If you
+% have to, enclose the optional argument in additional curly braces:
+% \begin{verbatim}
+% \experiment[{one, two, three}]{The one, the two and the three}
+% \end{verbatim}
+%
+% \DescribeMacro{\subexperiment} Below |\experiment| you can use
+% |\subexperiment| which works in the same way and produces
+% sub-indexentries. It is intended for sections like ``design,
+% realization, evaluation'' or ``preparation, purification,
+% measurement''.
+%
+%
+% \subsection{Advanced Usage: Experiment Abbreviations}
+% \label{sec:abkurzungen}
+%
+% \DescribeMacro{\newexperiment}
+% If one uses slightly different wording (or spelling) in two occurences
+% of the same experiment, they will get different index entries. To
+% avoid this, one can define abbreviations for frequently used
+% experiment headlines, toc and index entries. This is done with the macro
+%
+% |\newexperiment{<abbrev>}[<short form>]{<long form>}|
+%
+% Here, |<abbrev>| is the abbreviation that can be given later to make
+% \LaTeX\ use the |<long form>| and |<short form>|. The short form is
+% for index, table of contents and running title, and giving it is
+% optional. When using the abbreviation, specify it \emph{without}
+% prepending a backslash, i.e. |\experiment{abbrev}|. Abbreviations may
+% contain any char except the backslash, the tilde (\textasciitilde),
+% commas and spaces.
+%
+% \DescribeMacro{\newsubexperiment}
+% For |\subexperiment|, there is an analogous macro,
+% |\newsubexperiment|.
+%
+% If you try to define an abbreviation that has already been used, you
+% will get an error message. You can use the same abbreviation for one
+% experiment and one subexperiment entry (although doing this may cause
+% confusion, not to TeX, but to you). If you leave out the optional
+% argument, the long form is also used for index and table of contents.
+%
+% Usually you just type |\experiment{abbrev}|, but you can also combine
+% a varied text in the long form with an abbreviation in the optional
+% argument: |\experiment[abbrev]{varied text}|, to make sure the index
+% stays simple. You cannot use a free text optional argument with an
+% abbreviation in the mandatory argument (because the abbreviation yet
+% has an associated index entry). But it is, in principle, possible to
+% use two different abbreviations in optional and mandatory argument -
+% but only as long as both yield the same index entry.
+%
+%
+% \subsection{Fancy stuff: Multiple index entries for experiments}
+% \label{sec:mult-index-entr}
+%
+% Sometimes one performs corresponding working steps of different
+% experiments in parallel -- this complicates index entries. Consider
+% that by some screening method you have identified the substances A152
+% and B96 from a combinatorial library as promising drugs
+% against some disease. The next things to do is to verify their exact
+% structure, composition or sequence and establish a medium-scale
+% preparation protocol for further characterization. Probably you can
+% save time by doing some of these steps in parallel, but you will end
+% up with index entries like ``A152 and B96, sequencing'' -- and two
+% months later you will have to remember wether you sequenced B96
+% together with A152 or rather, the following week, with A43 and
+% C12. Therefore it would be nice to get two index entries for the
+% experiment ``Sequencing of A152 and B96'', namely ``A152, sequencing''
+% and ``B96, sequencing''. And you can have exactly that.
+%
+% \DescribeMacro{\experiment}\DescribeMacro{\subexperiment}
+% In fact the syntax for both |\experiment| and |\subexperiment| allows
+% for a comma separated list in the optional argument. The first element
+% will be used for table of contents and page head, and the following
+% elements will produce index entries. Suppose you have defined the
+% abbreviations A152-seq and \mbox{B96-seq}, you can thus say:
+% \begin{verbatim}
+% \experiment[Sequencing of A152 and B96, A152-seq, B96-seq]{Sequencing
+% of inhibitor candidates A152 and B96}
+% \end{verbatim}%
+% and get what you want. Spaces before and after the commas will be
+% ignored. You're free to use abbreviations or free text anywhere, but
+% for the index entries only abbreviations really make sense.
+%

+%
+% \section{Initialization}
+%
+% \subsection{Options}
+%
+% Some packages the user might use have to be loaded before hyperref, so
+% this class cannot load it internally. However, we have to take care of
+% it because of two reasons: One is that we need to provide it with some
+% macros for our new sectioning levels, the more important is that we cannot
+% redefine |\addcontentsline| before hyperref has done it. But we can't
+% simply delay this until after hyperref has been loaded, since this
+% might never occur.
+%
+% \changes{v1.1}{2003/05/20}{removed hardwired KOMA option openany}
+%
+% Therefore the user has to specifiy wether she intends to use it, using
+% the option |hyperref|.
+%
+% \begin{macrocode}
+\newif\ifwe@use@hyperref\we@use@hyperreffalse
+\DeclareOption{hyperref}{\we@use@hyperreftrue}
+% \end{macrocode}
+%
+% The rest is just passed to |scrbook.cls|:
+%
+% \begin{macrocode}
+\DeclareOption*{\PassOptionsToClass{\CurrentOption}{scrbook}}
+\ProcessOptions\relax
+\LoadClass{scrbook}
+% \end{macrocode}
+%
+% \subsection{Load the makeidx package}

+% execute compatibility definitions if it \emph{is} loaded}
+% \begin{macrocode}
+\RequirePackage{makeidx} \makeindex
+% \end{macrocode}
+%
+% \section{Experiment abbreviations}
+% \label{sec:experiment-abbr}
+%
+% To facilitate the creation of the index (specifically to avoid that
+% little differences or typos mess it up), the user may define
+% abbreviations for his experiment (and subexperiment) headings. This
+% can be done using the macro |\newexperiment|. It's first argument is
+% the abbreviation, then comes an optional short form for index
+% entries, table of contents and running titles. Last comes the
+% mandatory title argument.
+%
+% Then we check wether |\newexperiment| has been called with an optional
+% argument, and call the respective commands. |\@ifnextchar| looks for
+% the first character after the first argument, and keeps it. Thus, the
+% following macros get the same arguments that |\newexperiment| had.
+%
+% \begin{macrocode}
+\def\newexperiment#1{%
+ \@ifnextchar [{\opt@arg@newexperiment{#1}}%
+ {\nopt@arg@newexperiment{#1}}%]
+}
+% \end{macrocode}
+%
+% The long and short forms for \textit{\texttt{abbrev}} are assigned to
+% |\long@|\textit{\texttt{<abbrev>}} and
+% |\short@|\texttt{\textit{<abbrev>}}, respectively. After checking wether
+% \textit{\texttt{abbrev}} has not yet been used, the second argument is assigned
+% to the long and short form for the case when there was no optional
+% argument. In case of an optional argument, this is used for the
+% short form.
+%
+% \begin{macrocode}
+\def\nopt@arg@newexperiment#1#2{%
+ \@ifundefined{long@exp@#1}{%
+ \@namedef{long@exp@#1}{#2}%
+ \@namedef{short@exp@#1}{#2}%
+ }{%
+ \ClassError
+ {labbook}
+ {experiment abbreviation yet defined}
+ {The abbreviation for an experiment that you wanted to define
+ with this command has already been defined.}%
+ }
+}
+\def\opt@arg@newexperiment#1[#2]#3{%
+ \@ifundefined{long@exp@#1}{%
+ \@namedef{long@exp@#1}{#3}%
+ \@namedef{short@exp@#1}{#2}%
+ }{%
+ \ClassError
+ {labbook}
+ {experiment abbreviation yet defined}
+ {The abbreviation for an experiment that you wanted to define
+ with this command has already been defined.}%
+ }
+}
+% \end{macrocode}
+%
+% The same is done for |\subexperiment|. Any subexperiment abbreviation
+% may be used within any experiment.
+%
+% \begin{macrocode}
+\def\newsubexperiment#1{%
+ \@ifnextchar [{\opt@arg@newsubexperiment{#1}}%]
+ {\nopt@arg@newsubexperiment{#1}}%
+}%
+\def\nopt@arg@newsubexperiment#1#2{%
+ \@ifundefined{long@subexp@#1}{%
+ \@namedef{long@subexp@#1}{#2}%
+ \@namedef{short@subexp@#1}{#2}%
+ }{%
+ \ClassError
+ {labbook}
+ {experiment abbreviation yet defined}
+ {The abbreviation for an experiment that you wanted to define
+ with this command has already been defined.}%
+ }%
+}%
+\def\opt@arg@newsubexperiment#1[#2]#3{%
+ \@ifundefined{long@subexp@#1}{%
+ \@namedef{long@subexp@#1}{#3}%
+ \@namedef{short@subexp@#1}{#2}%
+ }{%
+ \ClassError
+ {labbook}
+ {experiment abbreviation yet defined}
+ {The abbreviation for an experiment that you wanted to define
+ with this command has already been defined.}%
+ }%
+}%
+% \end{macrocode}
+%
+% Note that the usage is |\experiment{|\textit{\texttt{abbrev}}|}|,
+% \emph{not} |\experiment{\|\textit{\texttt{abbrev}}|}|
+%
+% \section{Defining internal macros}
+% \label{sec:defin-intern-macr}
+%
+% We first define some internal helper macros that we will use for
+% different purposes.
+%
+% \subsection{Macros for argument parsing}
+% \label{sec:macr-argum-pars}
+%
+% \subsubsection{Parsing a comma separated list}
+% \label{sec:pars-comma-separ}
+%
+% The new sectioning commands can be used with a comma separated list of
+% items in the optional argument (see below, \ref{sec:optarg-exp}), and
+% we will be constructing a similar list if there is one more index entry
+% for one sectioning command. To parse this list, we use code that is
+% essentially taken from |keyval.sty| (page 4 in its manual).
+%
+% First we need some helper macros. |\FK@@sp@def| defines the control
+% sequence in its first argument to expand to its second argument, but
+% with any leading or trailing whitespace removed.
+%
+% \begin{macrocode}
+\def\@tmpA#1{%
+\def\FK@@sp@def##1##2{%
+ \futurelet\FK@tempa\FK@@sp@d##2\@nil\@nil#1\@nil\relax##1}%
+\def\FK@@sp@d{%
+ \ifx\FK@tempa\@sptoken
+ \expandafter\FK@@sp@b
+ \else
+ \expandafter\FK@@sp@b\expandafter#1%
+ \fi}%
+\def\FK@@sp@b#1##1 \@nil{\FK@@sp@c##1}%
+ }%
+\def\FK@@sp@c#1\@nil#2\relax#3{\FK@toks@{#1}\edef#3{\the\FK@toks@}}%
+\newtoks\FK@toks@%
+\@tmpA{ }%
+% \end{macrocode}
+%
+% Now we define a way to parse the optional argument and break it at
+% every comma. |\fk@getcommasep@list| is a wrapper macro. It executes
+% its first argument once before the list is read, assigns its further
+% arguments to actions that will be done while going through the list,
+% and then calls |\fk@@getcommasep@list| which takes as its argument the
+% first element of the list after it, i.e. everything up to the first
+% comma. It then works through the previously defined actions with this
+% element and then calls itself recursively, taking the next element as
+% its argument. |\fk@getcommasep@list| has to be called with
+% |<list>,\relax,|. Therefore, when all elements of the list have been
+% used, |\relax| is the next, and the recursion ends.
+%
+% \begin{macrocode}
+\newcounter{fk@commasep@argnumber}%
+\def\fk@getcommasep@list#1#2#3#4#5#6{%
+ \setcounter{fk@commasep@argnumber}{0}%
+ #1
+ \def\fk@commasep@beforebranch{#2}%
+ \def\fk@commasep@firstelement{#3}%
+ \def\fk@commasep@furtherelements{#4}%
+ \def\fk@commasep@afterlastelement{#5\empty}%
+ \def\fk@commasep@aftereachelement{#6}%
+ \fk@@getcommasep@list
+}
+\def\fk@@getcommasep@list#1,{%
+ \stepcounter{fk@commasep@argnumber}%
+ \fk@commasep@beforebranch%
+ \ifx\relax#1%
+ \fk@commasep@afterlastelement%
+% \end{macrocode}
+%
+% The counter has been incremented, and if we are already after the
+% last element (so the argument was |\relax|), then
+% |\fk@commasep@afterlastelement| (the fifth argument to the wrapper
+% macro) is executed.
+%
+% The |\else|-branch means we have a real list element. We assign it (with
+% whitespace removed) to |\fk@commasep@arg|. Then we check the counter
+% wether we are working with the first element of the list, or with
+% subsequent elements, and execute the respective commands (arguments
+% number 3 and 4 to the wrapper macro).
+%
+% \begin{macrocode}
+ \else%
+ \FK@@sp@def\fk@commasep@arg{#1}%
+ \ifnum\c@fk@commasep@argnumber=1%
+ \fk@commasep@firstelement%
+ \else%
+ \fk@commasep@furtherelements%
+ \fi%
+% \end{macrocode}
+%
+% After that, the sixth argument is executed which has been assigned to
+% |\fk@commasep@aftereachelement|, and the macro calls
+% itself again to take the next element.
+%
+% \begin{macrocode}
+ \fk@commasep@aftereachelement%
+ \expandafter\fk@@getcommasep@list%
+ \fi%
+}
+% \end{macrocode}
+%
+% Index entries for a sectioning level may contain commas, therefore
+% using a comma separated list for them is not a good idea. We just copy
+% the above definitions, but use |@--@| as the delimiter. Should you
+% ever have to use this in an index entry, you need to define a command
+% that typesets it and put this command in your optional argument, or
+% the abbreviation definition.
+%
+% \begin{macrocode}
+\newcounter{fk@atdashsep@argnumber}%
+\def\fk@getatdashsep@list#1#2#3#4#5#6{%
+ \setcounter{fk@atdashsep@argnumber}{0}%
+ #1
+ \def\fk@atdashsep@beforebranch{#2}%
+ \def\fk@atdashsep@firstelement{#3}%
+ \def\fk@atdashsep@furtherelements{#4}%
+ \def\fk@atdashsep@afterlastelement{#5\empty}%
+ \def\fk@atdashsep@aftereachelement{#6}%
+ \fk@@getatdashsep@list

+% \subsubsection{Parsing lists in the optional argument}
+% \label{sec:pars-lists-opti}
+%
+% Now we define a macro that uses |\fk@getcommasep@list| to parse the
+% comma separated list in the optional argument of |\experiment| and
+% |\subexperiment| (see \ref{sec:optarg-exp}). Its only declared argument
+% is the sectioning level specifier (|exp| or |subexp|), but it should
+% be called with the comma separated list (ending with |\relax,|)
+% following the specifier. This specifier is stored in the macro
+% |\fk@explevel| to make its usage more clear.
+%
+% First |\ifmore@thanone@item| is defined. It will be used to
+% conditionally trigger actions after the last element. Before
+% starting to iterate over the list, i.e. in the first argument to
+% |\fk@getcommasep@list|, we set this to false.
+%
+% \begin{macrocode}
+\newif\ifmore@thanone@item%
+\def\fk@parse@optarg{%
+ \fk@getcommasep@list{%
+ \more@thanone@itemfalse%
+ }{%
+ }{%
+% \end{macrocode}
+%
+% There's nothing to be done on every iteration before branching, so the
+% second argument to |\fk@getcommasep@list| is empty. The third is
+% executed for the first element in the list. We simply define the macro
+% |\fk@current@tocentry| as this first element for later use.
+% |\@onelevel@sanitize| changes |\fk@commasep@arg| to consist only of
+% strings, not command sequences. This is necessary because hyperref
+% will give an error with certain command sequences in bookmarks etc,
+% e.g. with |\textit| which expands to |\protect\textit|. Wether this
+% item will only be used for the toc and running title, or wether it
+% additionally is put into the index (namely if there is only this first
+% argument) cannot be decided now.
+%
+% \begin{macrocode}
+ \@onelevel@sanitize{\fk@commasep@arg}%
+ \protected@edef\fk@current@tocentry{\fk@commasep@arg}%
+ }{%
+% \end{macrocode}
+%
+% If there is at least a second element\footnote{note that it
+% doesn't make sense to use a list with two elements - there will
+% be only one index entry, so you can just as well use only one.
+% The only difference will be that you get the possibility to have
+% different wording in the index entry \emph{and} the toc entry
+% and the section heading, which I would try to avoid.}, we set
+% |\ifmore@thanone@item| to |true|, then assign the currently
+% processed list element to |\fk@currentarg|, appending a space only
+% after we have made sure there will be no problems with fragile
+% commands. Then we check wether it is an abbreviation for the
+% current sectioning level. According to the result, we create the
+% text to put in the index (|\fk@current@arg| itself or the text the
+% abbreviation stands for). Then we call |\fk@buildindexlist| (see
+% below) with it to add it to the index list for the current sectioning
+% commands.
+%
+% \begin{macrocode}
+ \more@thanone@itemtrue%
+ \protected@edef\fk@currentarg{\fk@commasep@arg}%
+ \@onelevel@sanitize{\fk@currentarg}%
+ \protected@edef\fk@currentarg@withspace{\fk@currentarg\space}%
+ \expandafter\fk@checkifabbrev@arg%
+ \fk@currentarg@withspace&{long@\fk@explevel}%
+ \ifabbrev@defined%
+ \expandafter\protected@edef%
+ \csname fk@current@\fk@explevel name\expandafter%
+ \endcsname{%
+ \csname short@\fk@explevel @\fk@currentarg\endcsname}%

+ \csname fk@current@\fk@explevel name\endcsname{%
+ \fk@currentarg}%
+ \expandafter\fk@buildindexlist{\fk@currentarg}
+ \fi%
+ }{%
+% \end{macrocode}
+%
+% After the last element, the procedure of sanitizing, space
+% appending and abbreviation checking is repeated. Because this is
+% done after the last element, the result of the check will not be
+% overwritten by other index elements. If there was only one element
+% in the optional argument, we have to add the content of
+% |\fk@current@tocentry| to the (still empty) indexlist.
+%
+% In this case, there is nothing to be done after each processed
+% list element, so the last argument to |\fk@getcommaseplist| is
+% empty.
+%
+% \begin{macrocode}
+ \protected@edef\fk@currentarg{\fk@current@tocentry}%

+ }{%
+ }%
+}
+% \end{macrocode}
+%
+%
+% \subsubsection{Building and using the list of index entries}
+% \label{sec:building-list-index}
+%
+% The text to be indexed for every sectioning command is kept in a comma
+% separated list, even if there is only one element. This list is build
+% by prepending the new element to the expansion of the list. First, the
+% lists (for experiments and subexperiments) are defined (as empty
+% lists). The macros that call |\fk@buildindexlist| have to properly set
+% |\fk@explevel| to |exp| or |subexp|, so that the new element gets into
+% the right list.
+%
+% \begin{macrocode}
+\def\fk@exp@indexlist{}%
+\def\fk@subexp@indexlist{}%
+\def\fk@buildindexlist#1{%
+ \def\@tmpA{exp}
+ \ifx\fk@explevel\@tmpA
+ \protected@edef\fk@exp@indexlist{#1§\fk@exp@indexlist}
+ \else
+ \protected@edef\fk@subexp@indexlist{#1§\fk@subexp@indexlist}
+ \fi
+}
+% \end{macrocode}
+%
+% To write index entries for each list element, we use
+% |\fk@getcommasep@list| again. Here there is no difference between
+% first and further elements, so we just define commands in the sixth
+% argument, which is processed once for every element. The list never
+% contains abbreviations, but always the text itself, so we just call
+% |\fk@@writeindex| with the element.
+%
+% \begin{macrocode}
+\def\fk@useindexlist{%
+ \fk@getatdashsep@list{}{}{}{}{}{%
+ \fk@@writeindex{\fk@atdashsep@arg}%
+ }%
+}%
+% \end{macrocode}
+%
+% |\fk@@writeindex| handles the differences in index writing for
+% experiments and subexperiments. If a new experiment is started (or
+% closed), then an index for every list element has to be written:
+%
+% \begin{macrocode}
+\def\fk@@writeindex#1{%
+ \def\@tmpA{exp}%
+ \ifx\fk@explevel\@tmpA%
+ \fk@writeindex{#1}%
+ \else%
+% \end{macrocode}
+%
+% If we are writing index entries for a subexperiment, things get more
+% complicated, because the experiment \emph{and} the subexperiment
+% might have more than one associated index entry. Therefore we have to
+% iterate over both |\fk@exp@indexlist| and |\fk@subexp@indexlist|. To
+% achieve this, for a subexperiment (where |\fk@explevel| is |subexp|),
+% |\fk@useindexlist| will be called with
+% |\fk@|\textit{exp}|@indexlist|, and |\fk@parselevel| is set
+% to |exp|. When |\fk@openindex| is called with explevel
+% |subexp|, but parselevel |exp|, its argument is
+% assigned to |\fk@current@expname|, the parselevel is changed to
+% |subexp|, and |\fk@useindexlist| is called again with
+% |\fk@|\textit{subexp}|@indexlist|. When doing this,
+% |\fk@openindex| will be called again, but since now the parselevel
+% is |subexp|, we get into the other branch. After processing
+% |\fk@subexp@indexlist| is finished, we have to continue processing
+% the next elements in |\fk@exp@indexlist|. Therefore we reset the
+% parselevel to |exp|.
+%
+% \begin{macrocode}
+ \ifx\fk@parselevel\@tmpA% we are iterating over the current list
+ % of experiments
+ \protected@edef\fk@current@expname{#1}
+ \def\fk@parselevel{subexp}
+ \expandafter\fk@useindexlist\fk@subexp@indexlist\relax§%
+ \def\fk@parselevel{exp}
+ \else
+% \end{macrocode}
+%
+% When processing the subexperiment's index list, we get into this
+% branch, and now for every subexperiment index element an entry is made
+% for the current meaning of |\k@current@expname|.
+%
+% \begin{macrocode}
+ \fk@writeindex{\fk@current@expname!#1}%
+ \fi
+ \fi%
+}%
+% \end{macrocode}
+%
+% The previous procedure made use of |\fk@writeindex| which is never
+% defined itself. It is |\let| to |\fk@openindex| or |\fk@closeindex|,
+% depending on where it is called. The first writes index entries which
+% open a range, i.e. §\index{text|(}§, the second closes the ranges
+% again (§\index{text|)}§).
+%
+% \begin{macrocode}
+\def\fk@openindex#1{\index{#1|(}}%)
+\def\fk@closeindex#1{\index{#1|)}}%)
+% \end{macrocode}
+%
+% \subsection{Checking for abbreviation usage}
+% \label{sec:check-abbr-usage}
+%
+% The next few macros are used to check wether an abbreviation or a
+% text was used as the argument of |\(sub)experiment|. First a little
+% helper macro:
+%
+% \begin{macrocode}
+\def\muST@bE@emPTy{\message{Numquam videbor}}%
+% \end{macrocode}
+%
+% |\fk@checkifabbrev@arg| is defined so that its first argument ends
+% with a space and the second only at the \&-sign; it is called with a
+% space appended to the item to check. Thus, if the second argument
+% isn't empty, there was a space in the item itself, and it cannot be an
+% abbreviation. If the second argument is empty, we check wether we have
+% an abbreviation using |\fk@checkfirst|:
+%
+% \begin{macrocode}
+\newif\ifabbrev@defined%
+\def\fk@checkifabbrev@arg #1 #2&#3{%
+ \ifx\muST@bE@emPTy#2\muST@bE@emPTy%
+ \protected@edef\@tmpA{#1\space}%
+ \expandafter\fk@checkfirst\@tmpA{#3}%
+ \else%
+ \abbrev@definedfalse%
+ \fi%
+}%
+% \end{macrocode}
+%
+% The first argument of |\fk@checkfirst| ends at the first space - note that
+% |\fk@currentarg| was defined with a space appended. This is necessary because
+% we have to be able to cut |\fk@currentarg| in words, not in single
+% characters. The second argument to |\fk@checkfirst| specifies the
+% level we are on (experiment or subexperiment).
+%
+% The macro now checks wether the requested abbreviation has been
+% defined, and sets the conditional accordingly:
+%
+% \begin{macrocode}
+\def\fk@checkfirst #1 #2{%
+ \@ifundefined{#2@#1}{\abbrev@definedfalse}{\abbrev@definedtrue}%
+}%
+% \end{macrocode}
+%
+% \subsection{Closing the index entries}
+% \label{sec:closing-entries}
+%
+% This macro, |\fk@close@labindex|, will be used in a couple of
+% circumstances to close open index ranges. First we make
+% |\fk@writeindex| produce entries that close the index ranges. If there
+% has been no experiment on the current |\labday|, then |\fk@explevel|
+% is undefined, and we don't do anything. Otherwise the experiment level
+% is determined, and |\fk@@close@labindex| is called appropriately.
+%
+% \changes{v1.0a}{2003/04/29}{removed wrong index closing for
+% subexperiments}
+% \begin{macrocode}
+\def\fk@close@labindex{%
+ \let\fk@writeindex\fk@closeindex%
+ \@ifundefined{fk@explevel}{}{%
+% \end{macrocode}
+%
+% If |\fk@explevel| is |exp|, then we need to close any open experiment
+% \emph{and} subexperiment index ranges. We first handle the
+% subexperiment. Before we call the macro that does it, we set
+% |\fk@explevel| to |subexp| and |\fk@parselevel| to |exp|, as required
+% by |\fk@@writeindex| (see \ref{sec:building-list-index}), and after
+% that we reset it to |exp| to close the experiment ranges themselves.
+% If |\fk@explevel| is |subexp|, however, we just call the closing
+% macro:
+%
+% \begin{macrocode}
+ \def\@tmpA{exp}%
+ \ifx\fk@explevel\@tmpA%
+ \def\fk@parselevel{exp}%
+ \def\fk@explevel{subexp}%
+ \fk@@close@labindex%
+ \def\fk@explevel{exp}%
+ \fk@@close@labindex%
+ \else%
+ \fk@@close@labindex%
+ \fi%
+ }%
+}%
+% \end{macrocode}
+%
+% |\fk@@close@labindex| calls |\fk@useindexlist| -- always with
+% the argument |\fk@exp@indexlist| -- and then flushes the list
+% for the current explevel.
+%
+% \begin{macrocode}
+\def\fk@@close@labindex{%
+ \expandafter\fk@useindexlist\fk@exp@indexlist\relax§%
+ \expandafter\def\csname fk@\fk@explevel @indexlist\endcsname{}%
+}
+% \end{macrocode}
+%
+%
+% \section[Defining the new sectioning commands]{Defining the new
+% sectioning commands \textbackslash\texttt{labday} and
+% \textbackslash\texttt{(sub)experiment}}
+% \label{sec:newsectcommands}
+%
+% First we define the counters. Footnote numbers are reset every day.
+%
+%\changes{v1.1a}{2003/06/13}{Let footnote numbering be reset every day}
+% \begin{macrocode}
+\newcounter{labday}
+\newcounter{experiment}[labday]
+\newcounter{subexperiment}[experiment]
+\@addtoreset{footnote}{labday}
+% \end{macrocode}
+%
+% If somebody uses |\subsubsection|, this has to be reset
+% properly. The marks have to be let to |\@gobble| initially:
+%
+% \begin{macrocode}
+\@addtoreset{subsubsection}{subexperiment}
+\let\experimentmark\@gobble
+\let\subexperimentmark\@gobble
+% \end{macrocode}
+%
+% The level of sections is designed to be used to classify an
+% experiment. The level
+% below that, usually subsection, is redefined as |\subexperiment|. It
+% should be used for things like ``rationale'', ``preparations'', or
+% ``evaluation'', or the like, and will also get into the toc and index:
+%
+% \begin{macrocode}
+\setcounter{tocdepth}{3}
+% \end{macrocode}
+%
+% Thus, chapters, sections and subsections go into the toc besides
+% labdays, experiments and subexperiments, but this should only be
+% used for things in |\frontmatter| or at the start of |\mainmatter|.
+%
+% Besides that, nothing is done in this class to format table of
+% contents and index. This can be done individually with different
+% packages on CTAN.
+%
+%\subsection{Defining experiment}
+%\label{sec:defining-experiment}
+%
+% \begin{macrocode}
+\def\experiment{%
+% \end{macrocode}
+%
+% The first thing we do is close the index entry for the preceding
+% |\experiment| and |\subexperiment|. Thus, this will be done before a
+% potential page break. The macro |\fk@close@labindex| will be defined
+% later, see \ref{sec:closing-entries}. Then we set
+% |\iflower@sectionlevel| to |false| -- this might have been set true by
+% a previously used |\subsubsection|, were no indexing should be done.
+%
+% \begin{macrocode}
+ \def\fk@explevel{exp}
+ \fk@close@labindex%
+ \lower@sectionlevelfalse%
+% \end{macrocode}
+%
+% One can use the unstarred form with abbreviations, and with free text,
+% too. However, if there is more than just text in the free text, e.g. a
+% command like |\textit{...}|, then there will be an error message from
+% \TeX\ which is hard to understand. Therefore it is strongly
+% recommended to use free text only with the starred form.
+%
+% We descriminate between the starred and unstarred forms and first
+% define the unstarred version: It checks wether there is an optional
+% argument in square brackets and calls the respective macros:
+%
+% \begin{macrocode}
+ \@ifstar{\@sexperiment}{\@experiment}%
+}
+\def\@experiment{%
+ \@ifnextchar [{\opt@arg@experiment}{\nopt@arg@experiment}%
+}
+% \end{macrocode}
+%
+% \subsubsection{\textbackslash\texttt{experiment} without optional argument}
+%
+% First the case of no optional argument is defined. Either the one
+% argument is an abbreviation as defined by the user command
+% |\newexperiment|, or it is of free form. Checking which is not
+% straightforward, because we cannot simply put a whole sentence,
+% possibly with markup macros, into an |\@ifundefined|-command.
+%
+% \begin{macrocode}
+\def\nopt@arg@experiment#1{%
+ \def\fk@currentarg{#1 }\@onelevel@sanitize{\fk@currentarg}%
+ \expandafter\fk@checkifabbrev@arg\fk@currentarg&{long@exp}%
+% \end{macrocode}
+%
+% The first line in the definition has the effect that |\fk@currentarg|
+% contains the argument text, but everything is read as text, not as a
+% macro, even if it looks like it. Then |\fk@checkifabbrev@arg| is called
+% with this string of characters and (possibly) spaces as an argument
+% and an arbitrary delimiter, here \&. This macro, defined below,
+% changes the conditional |\ifabbrev@defined|.
+%
+% \begin{macrocode}
+ \ifabbrev@defined%
+% \end{macrocode}
+%
+% The case with an abbreviation, so we have to manually assign short
+% and long forms for |\@startsection|, and make sure that the short
+% form gets into the index. Indexing is done by calling
+% |\fk@buildindexlist| with the meaning of the abbreviation. It will
+% automatically used by |\addcontentsline|. The actual arguments for
+% |\@startsection| are just a copy of the |\section|-definition from
+% scrbook.cls.
+%
+% \begin{macrocode}
+ \fk@buildindexlist{\csname short@exp@#1\endcsname}%
+ \@startsection{experiment}{1}{\z@}%
+ {-3.5ex \@plus -1ex \@minus -.2ex}%
+ {2.3ex \@plus.2ex}%
+ {\raggedsection\normalfont\sectfont\nobreak\size@section\nobreak}%
+ [\@nameuse{short@exp@#1}]{\@nameuse{long@exp@#1}}%
+ \else%
+% \end{macrocode}
+%
+% |\else| is the case where the user just uses
+% the free form (or mistyped the abbreviation
+% - but that will show up in the dvi/pdf
+% file). |\@startsection| will |\@dblarg| the parameter itself.
+%
+% \begin{macrocode}
+ \expandafter\fk@buildindexlist{\fk@currentarg}
+ \@startsection{experiment}{1}{\z@}%
+ {-3.5ex \@plus -1ex \@minus -.2ex}%
+ {2.3ex \@plus.2ex}%
+ {\raggedsection\normalfont\sectfont\nobreak\size@section\nobreak}%
+ {#1}%
+ \fi%
+}%
+% \end{macrocode}
+%
+% \subsubsection{\textbackslash\texttt{experiment} with an optional argument}
+% \label{sec:optarg-exp}
+%
+% Now comes the case where |\experiment| was called with an optional
+% argument. The optional argument may consist of
+% \begin{itemize}
+% \item One arbitrary sentence with formatting \emph{without} commas, or
+% \item one previously defined abbreviation, or
+% \item a comma separated list of items. The items should usually be
+% abbreviations, the first may be an arbitrary sentence (with formatting).
+% \end{itemize}
+% In the latter case, the first one is used for the table of contents
+% and the running title, but \emph{not} for the index; the following are
+% put in the index. All this is achieved by calling
+% |\fk@parse@optarg|, after setting its parselevel to exp.
+%
+% \begin{macrocode}
+\def\opt@arg@experiment[#1]#2{%
+ \fk@parse@optarg#1,\relax,%
+% \end{macrocode}
+%
+% The checks regarding abbreviations get more complicated
+% here, we have to check the first item in the optional argument -- this is
+% done by the macro |\fk@parse@optarg|~--, and the long argument.
+%
+% \begin{macrocode}
+ \ifabbrev@defined%
+ \def\fk@currentarg{#2 }\@onelevel@sanitize{\fk@currentarg}%
+ \expandafter\fk@checkifabbrev@arg\fk@currentarg&{long@exp}%
+ \ifabbrev@defined%
+% \end{macrocode}
+% This is the strange, but working case with two predefined
+% forms. We have to check wether they are equal. In fact the
+% user may use different abbreviations as long as the short
+% forms expand to the same index/toc entry.
+%
+% The check works like this: The first |\expandafter| delays the |\ifx|
+% conditional until the next token, |\csname|, has been
+% expanded. Expansion of |\csname|, however, scans for an
+% |\endcsname|, but before it gets there (to the first one), it
+% encounters the second |\expandafter|. Therefore, first the last
+% |\csname| is expanded, yielding the macro |\short@exp@<second-abbrev>|, then the
+% first is expanded, and we get\\
+% |\ifx\short@exp@<first-abbrev>\short@exp@<second-abbrev>|.
+%
+% \begin{macrocode}
+ \expandafter\ifx%
+ \csname short@exp@\fk@current@tocentry\expandafter%
+ \endcsname\csname short@exp@#2\endcsname%
+ \@startsection{experiment}{1}{\z@}%
+ {-3.5ex \@plus -1ex \@minus -.2ex}%
+ {2.3ex \@plus.2ex}%
+ {\raggedsection\normalfont\sectfont\nobreak\size@section\nobreak}%
+ [\@nameuse{short@exp@\fk@current@tocentry}]%
+ {\@nameuse{long@exp@#2}}%
+ \else%
+ \ClassError
+ {labbook}
+ {index entry and experiment title don't match}
+ {%

+ in the text). This is only possible if both would

+ entries. However, you requested the index

+ \fi%
+ \else%
+% \end{macrocode}
+%
+% This is the working case with a
+% predefined short form and a free
+% long form. We warn the user - she might
+% have accidentaly chosen the abbreviation:
+%
+% \begin{macrocode}
+ \ClassWarning{labbook}
+ {Using a pre-defined short form for this

+ \fi%
+ \else%
+% \end{macrocode}
+%
+% The |\fi| is the end of the conditional regarding the mandatory
+% argument, when the (first element of the) optional argument was an
+% abbreviation. The |\else| case now means that the optional argument is
+% a text, and we have to check again the state of the mandatory
+% argument:
+%
+% \begin{macrocode}
+ \def\fk@currentarg{#2 }\@onelevel@sanitize{\fk@currentarg}%
+ \expandafter\fk@checkifabbrev@arg\fk@currentarg&{long@exp}%
+ \ifabbrev@defined%
+% \end{macrocode}
+%
+% This is the error case with a free optional and
+% a predefined mandatory argument:
+%
+% \begin{macrocode}
+ \ClassError {labbook} {Manual short form conflicts with
+ abbreviated title} {You have used an optional argument to
+ \protect\experiment\space (the first element in

+ you have used an abbreviation defined\MessageBreak with
+ \protect\newexperiment. This doesn't make sense, so
+ I don't accept it.}%
+ \else%
+% \end{macrocode}
+%
+% This is the working case where

+% \subsection{Defining labday}
+% \label{sec:defining-labday}
+%
+% In mainmatter, |\labday| replaces chapter. (|\chapter| may still be
+% used and will get a toc entry, e.g. after |\backmatter|). |\labday| is
+% an extended |\addchap| (i.e. an un-numbered |\chapter| with toc entry
+% and assignment of a running headline) which additionally sets the
+% closing index entry for the preceding |\(sub)experiment|. After
+% closing, |\k@explevel| is made undefined, so that addcontentsline
+% won't try to open index ranges.
+%
+% \begin{macrocode}
+\newcommand*{\labday}{%
+ \def\fk@explevel{exp}%
+ \fk@close@labindex%
+ \let\fk@explevel\@undefined%
+ \refstepcounter{labday}%
+ \addchap%
+}%
+% \end{macrocode}
+%
+%
+% \subsection{Adjusting the definition of part}
+% \label{sec:adj-part}
+%
+% If part is used, it must also call |\fk@close@labindex|.
+%
+% \begin{macrocode}
+\let\fk@part\part
+\renewcommand*{\part}{%
+ \def\fk@explevel{exp}%
+ \fk@close@labindex%
+ \let\fk@explevel\@undefined%
+ \fk@part%
+}
+% \end{macrocode}
+%
+%
+% \subsection{Adjusting subsubsection}
+% \label{sec:adj-subsubsection}
+%
+% If somebody uses lower sectioning levels than |\subexperiment|, the
+% index lists are not affected, and thus |\addcontentsline| would again
+% open the index entries for the last |\subexperiment|. To avoid this,
+% we extend |\subsubsection|; it now sets the conditional
+% |\iflower@sectionlevel| to true. This will be checked by |\addcontentsline|.
+%
+% \begin{macrocode}
+\newif\iflower@sectionlevel
+\let\fk@oldsubsubsection\subsubsection%
+\renewcommand{\subsubsection}{%
+ \lower@sectionleveltrue%
+ \fk@oldsubsubsection%
+}
+% \end{macrocode}
+%
+% \subsection{Section numbering, floats and the table of contents}
+% \label{sec:adjust-section-number}
+%
+% Since the days will not be numbered, we want to also change the
+% numbering scheme for the new sectioning commands:
+%
+% \begin{macrocode}
+\renewcommand*\theexperiment{\@arabic\c@experiment}%
+\renewcommand*\thesubexperiment{%
+ \theexperiment.\@arabic\c@subexperiment}%
+% \end{macrocode}
+%
+% And for consistency also for the lower levels -- nobody will ever need
+% these numbered, will one?
+%
+% \begin{macrocode}
+\renewcommand*\thesubsubsection{%
+ \thesubexperiment.\@arabic\c@subsection}%
+\renewcommand*\theparagraph{%
+ \thesubsubsection.\@arabic\c@paragraph}%
+\renewcommand*\thesubparagraph{%
+ \theparagraph.\@arabic\c@subparagraph}%
+% \end{macrocode}
+%
+% And the floats:
+%
+% \begin{macrocode}
+\@addtoreset{figure}{labday}%
+\@addtoreset{table}{labday}%
+\renewcommand*\thefigure{%
+ \@arabic\c@figure}%
+\renewcommand*\thetable{%
+ \@arabic\c@table}%
+% \end{macrocode}
+%
+%
+% To be able to print a table of contents, we have to define
+% |\contentsline| for labday, experiment and subexperiment. We just copy the
+% definitions from |\chapter| and |\(sub)section|:
+%
+% \begin{macrocode}
+\let\l@labday\l@chapter%
+\let\l@experiment\l@section%
+\let\l@subexperiment\l@subsection%
+% \end{macrocode}
+%
+% \section{Building the index}
+% \label{sec:building-index}
+%
+% \subsection[Redefining addcontentsline]{Redefining \protect\verb|\@addcontentsline|}
+% \label{sec:redefining-addcont}
+%
+% If |\experiment| or |\subexperiment| are called, then
+% |\addcontentsline| is extended to open the index range entries
+% (closing is done by |\fk@close@labindex|, see above).
+%
+% Redefining is only done \emph{here} if we do not use |hyperref.sty|.
+% If the |hyperref| option has been specified, it is delayed until after
+% this package has been loaded, see section \ref{sec:hyperref-compat}.
+% What we do here in any case is define a macro that will do the real
+% defining of |\addcontentsline|.
+%
+% \changes{v1.0a}{2003/04/29}{don't load hyperref automatically, only
+% execute compatibility definitions if it \emph{is} loaded}

+% \begin{macrocode}
+\def\define@addcontentsline{%
+ \let\fk@old@addcontentsline\addcontentsline%
+ \def\addcontentsline##1##2##3{%
+% \end{macrocode}
+%
+% First, we call all the old commands. After that, we apply the changes,
+% starting with a bunch of checks: First wether we are called from a
+% sectioning command (writing to |toc|), not by a caption of a figure or
+% table; then wether |\fk@explevel| is defined (i.e. wether we are not
+% called by |\part|, |\labday| or a traditional sectioning command
+% outside mainmatter). And last wether we are not called by
+% subsubsection or lower.
+%
+% \begin{macrocode}
+ \fk@old@addcontentsline{##1}{##2}{##3}%
+ \def\@tmpA{toc}%
+ \def\@tmpB{##1}%
+ \ifx\@tmpA\@tmpB%
+ \@ifundefined{fk@explevel}{}{%
+ \iflower@sectionlevel\else%
+% \end{macrocode}
+%
+% We define |\fk@writeindex| to open ranges and then call
+% |\fk@useindexlist| with the experiment's indexlist -- as explained
+% above (see \ref{sec:building-list-index}), this is also correct for
+% subexperiments.
+%
+% \begin{macrocode}
+ \let\fk@writeindex\fk@openindex%
+ \expandafter\fk@useindexlist\fk@exp@indexlist\relax§%
+ \fi%
+ }%
+ \fi%
+ }%
+}%
+% \end{macrocode}
+%
+% Now let's see wether hyperref.sty is used, according to the class
+% option. If no, we can redefine |\addcontentsline| right now:
+%
+% \begin{macrocode}
+%
+\ifwe@use@hyperref\else%
+ \define@addcontentsline%
+\fi%
+% \end{macrocode}
+%
+%
+%\subsection{Making sure the last index range is closed}
+%
+% Since closing of the index entries is usually done by the subsequent
+% call of |\(sub)experiment|, the last would never be closed. The
+% closing has to be done at the begin of the appendix if there is one,
+% or at the end of mainmatter, if |\backmatter| is called, or at last at
+% the end of the document. The user should still be able to call
+% |\appendix| and |\backmatter| in arbitrary order, or not at all. To
+% decide at which place we close, we define a new conditional which is
+% initialized to be false. Then we define the command
+% |\fk@close@labindex| to close the index entries, if one is open (i.e.
+% if |\fk@current@(sub)expname| is not |\relax|). After closing, we
+% |\let| the index names to |\relax|.
+%
+% The |\appendix| command is extended to call |\fk@close@labindex| if
+% the conditional is still false, so is |\backmatter|. Additionally,
+% after closing the index entries |\fk@explevel| is made undefined, so
+% that subsequent calls of |\addcontentsline| don't even try to use
+% the (albeit empty) index lists.
+%

+\section{Generelles}
+
+\subsection{Rechtliches}
+
+Die F"uhrung von Laborb"uchern ist teilweise gesetzlich geregelt, oft
+stellen Institutionen zur Forschungsf"orderung weitere Anforderungen.
+In der Regel ist es daher \emph{nicht} erlaubt, ein Laborjournal
+lediglich in elektronischer Form zu f"uhren; teilweise sind gebundene
+B"ucher vorgeschrieben. Allerdings scheint es auch dort "ublich zu
+sein, die Notizen, die man w"ahrend der Experimente auf losen
+Bl"attern, in Computerdateien oder einem "`Schmierbuch"' gef"uhrt hat,
+mehr oder weniger regelm"a"sig ins gebundene Laborjournal zu
+"ubertragen.
+
+Aus diesem Grund scheint es mir vertretbar, mit einer elektronischen
+und einer parallelen ausgedruckten Fassung des Laborjournals zu
+arbeiten. Bei Bedarf kann die ausgedruckte Fassung geheftet oder
+gebunden werden, eine auf CD-ROM gebrannte Version sollte einem Buch
+an Beweiskraft nicht nachstehen. Dem stehen die gro"sen Vorteile v.a. einer
+PDF-Fassung gegen"uber: Volltextsuche, einfache Einbindung von
+Graphen und Bildern, M"oglichkeit der Verlinkung von Datendateien etc.

+\subsection{Merkmale}
+\label{sec:features}
+
+\begin{description}
+\item[Basisklasse] |labbook.cls| basiert auf der KOMA-Script-Klasse
+ |scrbook.cls| und bietet daher alle Möglichkeiten dieser Klasse, vom
+ Seitenlayout über Kopfzeilengestaltung und Absatzauszeichnung bis
+ hin zu Variationen des Layouts von \textit{floats} und
+ Randbemerkungen. Die Lektüre des scrguide wird sehr empfohlen!
+\item[Gliederung] Die Gliederung erfolgt zun"achst chronologisch,
+ statt |\chapter| wird |\labday| verwendet. Innerhalb eines Tages
+ wird nach Experimenten untergliedert -- das kann eine vollständige
+ Messung von der Planung bis zur Auswertung sein, aber auch ein
+ Arbeitsgang eines mehrere Tage dauernden Versuchs. |\experiment|
+ steht auf der Ebene von |\section|, zusätzlich steht
+ |\subexperiment| auf der |\subsection|-Ebene zur Verfügung. Darunter
+ gibt es die "ublichen Gliederungsebenen, auch wenn eine sehr tiefe
+ Schachtelung wenig sinnvoll erscheint -- man beachte das
+ |\minisec|-Kommando von KOMA-Script.
+\item[Index und Inhaltsverzeichnis] Wegen der chronologischen Gliederung ist ein
+ traditionelles Inhaltsverzeichnis nicht ausreichend, besonders wenn
+ Versuche in einem zusammenh"angenden Experiment an verschiedenen
+ Tagen durchgef"uhrt werden. Daher wird zusätzlich ein Index
+ ausgegeben. Der Index wird aus den Inhaltsverzeichnis-Einträgen der
+ Abschnittsbefehle erstellt. Als Argument für |\experiment| und
+ |\subexperiment| kann man auch vorher definierte Abkürzungen
+ verwenden. Dadurch soll die konsistente Erstellung des Index
+ erleichtert werden. Außerdem können einem Experiment mehrere
+ Indexeinträge zugeordnet werden.
+\item[hyperref-Integration] Die Klasse arbeitet gut mit dem Paket
+ |hyperref.sty| zur Erstellung von pdf-Dateien mit
+ Navigationsfunktionen zusammen.
+\end{description}
+
+
+\section{Benutzung}
+\label{sec:usage}
+
+
+\subsection{Initialisierung}
+\label{sec:options}
+
+Wenn man hyperref verwenden möchte \emph{muss} man die Klassenoption
+|hyperref| angeben:
+\begin{verbatim}
+\documentclass[hyperref]{labbook}
+\end{verbatim}
+Danach kann man hyperref und andere Pakete in der jeweils passenden
+Reihenfolge laden. Wird hyperref geladen, ohne die Option anzugeben,
+dann überschreibt es einige Änderungen, die in dieser Klasse in
+\LaTeX-Interna eingefügt werden. Umgekehrt werden diese Änderungen gar
+nicht erst durchgeführt, wenn man die Option |hyperref| angibt, aber
+das Laden des Paketes vergisst! Bei der Verwendung von hyperref
+sollte man außerdem die KOMA-Option |idxtotoc| in Erwägung ziehen: Der
+Index wird nämlich nicht nur in das Inhaltsverzeichnis aufgenommen,
+sondern auch in die PDF-Bookmarks.
+
+Ansonsten werden derzeit einfach alle Optionen an scrbook
+durchgereicht. Die Verwendung von |openany| bietet sich an, damit
+Labortage auf jeder Seite beginnen können.
+
+\section{Gliederungsbefehle}
+\label{sec:gliederungsbefehle}
+
+subsection{\textbackslash\texttt{labday}}
+label{sec:labday}
+
+\DescribeMacro{\labday} Der Befehl |\labday| kann verwendet werden, um
+eine nicht nummerierte "Uberschrift zu erzeugen. Ihr Text (bzw. der des
+optionalen Arguments) wird ins Inhaltsverzeichnis aufgenommen und als
+lebender Kolumnentitel gesetzt. In der Regel wird man einfach das
+Datum, vielleicht mit dem Wochentag, verwenden. |\labday| kümmert
+sich auch um die Indexeinträge der untergeordneten Gliederungspunkte;
+man sollte es nur innerhalb von mainmatter verwenden. Intern wird
+|\addchap| aufgerufen, es gibt keine Sternform und kein optionales
+Argument.
+
+\subsection{\textbackslash\texttt{experiment} und
+ \textbackslash\texttt{subexperiment}: Einfache Verwendung}
+\label{sec:exper-und-subexp}
+
+\DescribeMacro{\experiment} Innerhalb eines Tages k"onnen nummerierte
+"Uberschriften für einzelne Experimente mit
+\begin{verbatim}
+\experiment[<Kurzform>]{<Langform>}
+\end{verbatim}
+erzeugt werden. Ihr Text (bzw. der des optionalen Arguments) wird
+nicht nur ins Inhaltsverzeichnis und den Seitenkopf geschrieben,
+sondern auch in den Index. Dieser erleichtert die Orientierung,
+besonders wenn Experimente mehrfach oder "uber mehrere Tage hinweg
+durchgef"uhrt werden. Die Indexeintr"age geben nicht nur die Seiten
+des Beginns jedes Experiments an, sondern den ganzen Seitenbereich,
+und fassen zusammenhängende Bereiche des gleichen Experiments an
+unterschiedlichen Tagen zusammen.
+
+Beachten Sie, dass man im optionalen Argument keine Kommas verwenden
+darf, weil es auch eine durch Kommas abgetrennte Liste enthalten kann
+(s.\,u.). Wenn Sie doch ein Komma benötigen, schließen Sie das
+optionale Argument nochmals in geschweifte Klammern ein:
+\begin{verbatim}
+\experiment[{eins, zwei, drei}]{Die Eins, die zwei und die Drei}
+\end{verbatim}
+
+\DescribeMacro{\subexperiment} Das selbe gilt f"ur die darunter
+liegenden |\subexperiment|-Eintr"age. Sie sind f"ur Untergliederungen
+der Art "`Planung, Durchf"uhrung, Auswertung"' oder "`Herstellung,
+Reinigung, Messung"' vorgesehen.
+
+
+\subsection{Fortgeschrittene Verwendung: Abk"urzungen}
+\label{sec:abkurzungen}
+
+\DescribeMacro{\newexperiment} Wenn man für das gleiche Experiment an
+unterschiedlichen Stellen leicht unterschiedliche Formulierungen (oder
+Schreibungen) wählt, erhält man unterschiedliche Indexeinträge. Um
+dies zu vermeiden, kann man sich Abk"urzungen für häufig auftretende
+Experimente definieren. Dies geschieht mit dem Makro
+
+|\newexperiment{<abk>}{<Langform>}{<Kurzform>}|
+
+Dabei bezeichnet |<abk>| die Abk"urzung, mit der man auf die
+definierte |<Langform>| und |<Kurzform>| zugreifen kann (letztere für
+Index, Inhaltsverzeichnis und Kolumnentitel). Der Text der Abk"urzung
+ist dabei \emph{ohne} vorangestellten Backslash einzugeben, also als
+|\experiment{abk}|! Die Abk"urzungen d"urfen außer der Tilde
+(\textasciitilde), dem Komma und Leerzeichen sämtliche Zeichen
+enthalten.
+
+\DescribeMacro{\newsubexperiment} Für |\subexperiment| steht ein
+analoges Makro, |\newsubexperiment|, zur Verfügung.
+
+Bei jeder Verwendung eines dieser Makros wird "uberpr"uft, ob die
+gew"unschte Abk"urzung bereits verwendet wurde, und gegebenenfalls ein
+Fehler erzeugt. Gleichlautende Abk"urzungen f"ur |\experiment| und
+|\subexperiment| sind grunds"atzlich m"oglich, d"urften aber nur
+Verwirrung stiften (beim Benutzer, nicht bei \TeX). Wird das dritte
+Argument dieser Makros leer gelassen, so wird die Langform auch f"ur
+Index und Inhaltsverzeichnis verwendet.
+
+|\experiment| und |\subexperiment| k"onnen wie |\section| mit oder
+ohne optionales Argument verwendet werden, und zwar sowohl mit v"ollig
+frei gew"ahlten "Uberschriften (Kurz- und Langform) als auch mit einer
+Abk"urzung. Die Kombination einer Abk"urzung im optionalen Argument
+und einer variierten, freien Langform im Hauptargument ist m"oglich,
+die Verwendung eines frei formulierten optionalen Arguments mit einer
+Abk"urzung im Pflichargument f"uhrt jedoch zu einem Fehler, denn die
+Abk"urzung legt ja bereits einen Index- und Verzeichniseintrag fest.
+Die Verwendung zweier unterschiedlicher Abk"urzungen in optionalem und
+Pflichtargument ist m"oglich, wenn sie beide zum selben Indexeintrag
+f"uhren.
+
+
+\subsection{Mehrfache Indexeinträge}
+
+Manchmal führt man zusammenpassende Arbeitschritte für verschiedene
+Experimente parallel aus, das verkompliziert die Indexeinträge.
+Stellen Sie sich z.\,B. vor, Sie hätten mit einer Screening-Methode
+die Substanzen A152 und B96 aus einer kombinatorischen Bibliothek als
+vielversprechende Medikamente identifiziert. Als nächstes möchten Sie
+deren exakte Struktur, Zusammensetzung oder Sequenz verifizieren und
+eine Präparationsmethode für etwas größere Mengen entwickeln.
+Wahrscheinlich können Sie Zeit sparen, indem Sie einige dieser
+Schritte für beide Substanzen parallel ausführen, aber dann erhalten
+Sie einen Index mit Einträgen wie "`A152 und B96, Sequenzierung"' --
+und zwei Monate später sollen Sie sich erinnern, ob sie B96 zusammen
+mit A152 sequenziert haben oder stattdessen in der folgenden Woche mit
+A43 und C12. Daher wäre es praktisch, für das Experiment
+"`Sequenzierung von A152 und B96"' zwei Indexeinträge zu erhalten,
+nämlich "A152, Sequenzierung"' und "B96, Sequenzierung"'. Und genau
+das können Sie einfach erzeugen.
+
+\DescribeMacro{\subexperiment}\DescribeMacro{\experiment}
+Denn die Syntax von |\experiment| und |\subexperiment| erlaubt es,
+eine durch Kommata abgetrennte Liste im optionalen Argument zu
+verwenden. Das erste Element wird für das Inhaltsverzeichnis und die
+Kolumnentitel verwendet, und die folgenden Elemente liefern
+Indexeinträge. Angenommen, Sie haben die Abkürzungen A152-seq und
+B96-seq definiert, dann brauchen Sie nur zu schreiben:
+\begin{verbatim}
+\experiment[Sequenzierung A152 und B96, A152-seq,
+B96-seq]{Sequenzierung der Inhibitor-Kandidaten A152 und B96}
+\end{verbatim}
+und Sie erhalten was Sie wünschen. Leerzeichen vor und nach den
+Kommata werden ignoriert. Sie können überall Abkürzungen oder freien
+Text wählen, obwohl für die Indexeinträge wahrscheinlich nur
+Abkürzungen wirklich sinnvoll sind.
+
+
+\section{Implementierung}
+
+Die Implementierung ist auf Englisch dokumentiert und kann durch
+Übersetzung von |labbook.dtx| mit latex erhalten werden.
