+% a large collection of simple ``little helpers'' which  do not really warrant a
+% separate package on their own.
+% 
+% Included are, among other things, definitions of common units with preceeding
+% thinspaces and optionally following space, framed boxes where both width and
+% height can be specified, starting new odd or even pages, draft markers, notes,
+% conditional includes, including EPS files, and versions of enumerate and
+% itemize which allow the horizontal and vertical spacing to be changed.

+%
+% \section{Introduction}
+%
+% This package is a collection of helpful short macros which are not related to
+% each other.
+% 
+% Most of these macros are generally useful, but some will be useful to only a
+% few people, if at all.  They are combined here because any document I write
+% uses at least some of them.
+% 
+% The first version of this package dates back to 1994, and combined bits and
+% pieces from older \LaTeX2.09 packages into this one. This package was made
+% specifically for \LaTeXe.
+%
+%
+%
+% \section{User Manual}
+%
+%
+% \subsection{Units}
+%
+% A selection of units is defined. Because the names are short and could easily
+% clash with something else, units are only defined when the respective package
+% option is used. All defined units have the thinspace between the
+% number and the unit already included, so '|123\cm|' gives '123\,cm'.
+% 
+% The units defined by \option{unitBasic} redefine existing control sequences.
+% 
+% A degree symbol and commands for degree celsius and fahrenheit are provided.
+% Because |\degree| clashes with many thesis packages, \package{lhelp} will
+% define both |\degree| and |\Degree| to be the degree symbol (superscript
+% circle), if they are not defined already by the time \package{lhelp} is
+% loaded. Either way, |\celsius| and |\fahren| will work.
+% 
+% \DescribeMacro{\muunit}
+% |\muunit| produces just the micro ($\mu$) part of the unit and includes the
+% thinspace. If |\textmu| is defined (by e.g.\ \package{textcomp}), it will be
+% used instead of |$\mu$|.
+%
+% \DescribeOption{unitxspace}
+% With package option \option{unitxspace}, all defined units are followed by an
+% |\xspace|, which automatically insert white space if the unit is not followed
+% by punctuation. E.g. '|is 23\m long|' becomes 'is 23\,m\ long' instead of 'is
+% 23\,mlong'. See the |xspace| package for details.

+% \package{vmargin} was loaded before package \package{lhelp}, both options also
+% set the paper size to A4 and the margins to some more useful values.
+%
+%
+% \subsection{Draft markers}
+% 
+% \DescribeOption{draftmark}
+% Package option \option{draftmark} selects pagestyle plain and changes the page
+% footer to include the current date and the text ``DRAFT''. This works with the
+% standard pagestyles empty (which is not empty then), plain, and headings. It
+% obviously does not work with any custom pagestyles. This option does not
+% affect the page header.
+% 
+% \DescribeMacro{\draftname}
+% |\draftname| produces the ``DRAFT'' text.
+% 
+% \DescribeMacro{\draftfont}
+% |\draftfont| switches to the font with which the draft text is printed. It
+% takes one argument: the text to typeset in draft font.
+%
+% \DescribeOption{draftmarkps}
+% \DescribeMacro{\putdraftmarkps}
+% Same as option \option{draftmark}, but also writes a big ``DRAFT'' in gray
+% across the page.
+% Required are the \package{color} package, and either the  \package{graphics}
+% or \package{graphicx} package.
+% Packages \package{color} and \package{graphics} are loaded if necessary.
+% To load these packages with options, load them before \package{lhelp}.
+% It works with page styles empty, plain, and headings.
+% The page header is changed.
+% This uses a PostScript font (font family phv), so may require a PostScript
+% output device.
+% The actual mark is placed with |\putdraftmarkps|, which may have to be
+% redefined to accomodate a different |\draftname|. Its original definition can
+% be found via the index in the code section of this manual.
+% 
+% \DescribeOption{draftmarkpsonly}
+% Same as option \option{draftmarkps}, but only writes a big ``DRAFT'' in gray
+% across the page. I.e., it doesn't change the footer.
+% 
+% \subsection{Shortcuts and Symbols}
+% 
+% \DescribeOption{refshortcuts}
+% Package option \option{refshortcuts} defines several shortcuts for
+% cross-referencing chapter, tables, etc. This is currently only really useful
+% for English. Usage is the same as for |\ref|, except that ``chapter'' etc.\ is
+% also printed. Those shortcuts starting with an uppercase letter print a word
+% with an uppercase first letter.
+% 
+% For chapter, section, appendix, figure, table:
+% |\cref|,
+% |\Cref|,
+% |\sref|,
+% |\Sref|,
+% |\aref|,
+% |\Aref|,
+% |\fref|,
+% |\Fref|,
+% |\tref|,
+% |\Tref|
+%
+% For pages:
+% |\pgref|,
+% |\Pgref|
+%
+% For photos\footnote
+%     {(e.g. with the \package{photo} package, also by Volker Kuhlmann,
+%     available from CTAN)}:
+% |\phref|,
+% |\Phref|
+%
+% Examples: \examplepar\\
+% |\sref{s:mylabel}| produces |section~\ref{s:mylabel}|,\\
+% |\pgref{somepage}| produces |page~\pageref{somepage}|,\\
+% |\phref{p:photo1}| produces |photo~\ref{p:photo1}|,\\
+% |\Aref{s:a1}| produces |Appendix~\ref{s:a1}|.
+% 
+% 
+% \noindent
+% \DescribeMacro{\lineout}
+% \DescribeMacro{\ul}
+% \DescribeMacro{\ulbf}
+% Text with attributes. The text is taken as argument by these macros, and can't
+% be broken across lines. If it is necessary to break text into lines, try
+% Donald Arseneau's package \package{ulem}.
+%
+% \tableindent
+% \begin{tabular}{ll}
+%     |\ulbf{|\meta{text}|}|  &\ulbf{underlined bold}\\

+%     |\lineout{|\meta{text}|}| &\lineout{lined out}\\
+% \end{tabular}
+%
+% \noindent
+% \DescribeMacro{\textsubscript}
+% More shortcuts.
+% \LaTeX provides a |\textsuperscript|, but no |\textsubscript|, so we make one
+% here. |\textsubscript| is robust, and only defined by \package{lhelp} if it
+% is not already defined, in case \LaTeX\ does provide it in a future version.
+%
+% \tableindent
+% \begin{tabular}{ll}
+%     |\bs|, |\texttt{\bs}|   &\bs, \texttt{\bs}\\
+%     |\careof|               &\careof\ (the following space is included)\\
+%     |\textsubscript{|\meta{subscript}|}|  &Text\textsubscript{subscript}\\
+% \end{tabular}
+%

+% \end{tabular}
+% 
+% \noindent
+% \DescribeMacro{\eg}
+% \DescribeMacro{\ie}
+% \DescribeMacro{\etc}
+% \DescribeMacro{\ca}
+% \DescribeMacro{\resp}
+% These macros produce the English abbreviations ``e.g.'', ``i.e.'', and
+% ``etc.'', including the following normal space. This is for those (like
+% me) who always forget the backslash after the second period and thus get a
+% sentence-ending space with |\frenchspacing|.
+%
+% \DescribeMacro{\diameter}
+% This is a bad excuse for a diameter symbol. When the AMS symbols are available
+% (package \package{amssymb}), their |\varnothing| symbol will be used instead,
+% which is an acceptable solution.\\
+% \newcommand\diacludge{\mbox{\raise.15ex\hbox{o}\kern-.5em/}}%^^A

+%
+% 
+% \subsection{Boxes and rules}
+% 
+% \DescribeMacro{\fparbox}
+% A framed |\parbox|. The text material is set in paragraph mode, not LR-mode.
+% Unlike |\fbox{\parbox{\columnwidth}{...}}|, the width of the box generated by
+% |\fparbox| including the frame is \meta{width}. The default for \meta{width}
+% is |\hsize|. |\fboxrule| and |\fboxsep| are used as for |\fbox|.
+% 
+% \begin{pckcmd}
+%     |\fparbox|\optmeta{width}|(|\meta{parbox-optargs}|){|\meta{text}|}|
+% \end{pckcmd}
+%
+% \meta{parbox-optargs} are the optional arguments to |\parbox|, namely\\
+% |[POS][HEIGHT][INNER-POS]|.
+% 
+% Examples:
+% \par\vskip-\parskip\exampleindent
+% \begin{minipage}{60mm}
+%   \begin{verbatim}
+%     \fparbox{text...}
+%     \fparbox(){text...}
+%     \fparbox([t]){text...}
+%     \fparbox[50mm]([t][80mm][s]){text...}
+%   \end{verbatim}\fixendverbatim
+% \end{minipage}
+% 
+% \noindent
+% \fparbox{This box is produced with:\\\hspace*{7mm}\texttt{%^^A
+%     \bs fparbox\{This box is produced with:%^^A
+%     \bs\bs\bs hspace*\{7mm\}\bs texttt\{...\}\}}}
+% \vskip 1.5ex
+% 
+% \DescribeMacro{\xyfparbox}
+% Draws a framed box with \meta{text} in it. \meta{text} is set in a |\parbox|.
+% The outside of the frame has a size of \meta{width} times \meta{height}.
+% \begin{pckcmd}
+%    |\xyfparbox|\optmeta{pos}%^^A
+%       |{|\meta{width}|}{|\meta{height}|}{|\meta{text}|}|
+% \end{pckcmd}
+% The optional argument \meta{pos} becomes the first optional argument to
+% |\parbox| and defaults to |c|. |\parbox|'s \meta{inner-pos} is set to |c|.
+% |\fboxrule| and |\fboxsep| are used as for |\fbox|.
+% 
+% Example:\\
+% \exampleindent
+% \xyfparbox{60mm}{12mm}{\ttfamily \bs xyfparbox\{60mm\}\{12mm\}\{...\}}
+% \vskip 1.5ex
+%
+%
+% \DescribeMacro{\tlap}
+% \DescribeMacro{\blap}
+% Similar to plain's |\llap| and |\rlap|, the following overlapping boxes are
+% provided. All of these boxes have a size of zero. Their content overlaps into
+% adjacent page areas. Horizontal overlap uses |\hbox|, vertical overlap uses
+% |\vbox|.
+% 
+% \tableindent
+% \begin{tabular}{ll}
+%     |\lrlap|    &left and right (i.e. horizontally centred)\\
+%     |\tlap|     &top\\
+%     |\blap|     &bottom\\
+%     |\tblap|    &top and bottom (i.e. vertically centred)\\
+%     |\rtlap|    &right and top\\
+%     |\rblap|    &right and bottom\\
+% \end{tabular}
+% 
+% 
+% The following macros are useful for creating fill-in type forms.
+% 
+% \DescribeMacro{\vnull}
+% In analogy to |\null|: an empty |\vbox|.
+%
+% \DescribeMacro{\vnul}
+% An empty |\vbox| right at the top edge of the page. This uses
+% |\offinterlineskip| (and its own level of grouping).
+% 
+% \DescribeMacro{\hrulenull}
+% An |\hrule| with zero dimensions.
+%
+% 
+% \subsection{Notes}
+% 
+% \DescribeOption{printnotes}
+% Package option \option{printnotes}: print all notes in the document. The
+% default is not to.
+%
+% \begin{pckcmd}
+%     |\notes{|\meta{anytext}|}|\\
+%     |\nnotes{|\meta{anytext}|}|
+% \end{pckcmd}
+%
+% \DescribeMacro{\notes}
+% \DescribeMacro{\nnotes}
+% |\notes| prints \meta{anytext} if package option \option{printnotes} was
+% given, and discards \meta{anytext} otherwise.
+% |\nnotes| always discards \meta{anytext}; instead of deleting any notes you
+% never want printed, rename |\notes| to |\nnotes|.
+%
+% \DescribeMacro{\notesfont}
+% If any notes are printed, they are printed in |\notesfont|.
+%
+% \DescribeMacro{\bnotemark}
+% \DescribeMacro{\enotemark}
+% Printed notes are surrounded by a begin and an end mark which are printed into
+% the margin. These marks are generated by |\bnotemark| and |\enotemark|.
+%
+% \DescribeMacro{\ifprintnotes}
+% The conditional used to decide whether notes are printed is |\ifprintnotes|.
+% It can be used like |\ifprintnotes ... \fi|.
+%
+% 
+% \subsection{Conditional includes}
+% 
+% The conditional including macros provided here use an ``include level'' to
+% decide whether something is to be included or not. This is more powerful than
+% a binary include switch, and for example allows all xfig figures to be
+% included while no graphical images are. Graphical images are a common cause
+% for exploding file sizes and much increased processing times. For larger
+% documents the time saved while preparing can be considerable. For the final
+% document this is then simply turned off.
+% 
+% \DescribeWord{excludelevel}
+% \DescribeMacro{\includelower}
+% The counter |excludelevel| is the document's threshold for whether something
+% is included or not. The default is 5.
+% \begin{pckcmd}
+%     |\includelower{|\meta{includelevel}|}{|\meta{yes}|}{|\meta{no}|}|
+% \end{pckcmd}
+% |\includelower| expands to \meta{yes} if \meta{includelevel} is lower than
+% the counter |excludelevel|, otherwise it expands to \meta{no}.
+% 
+% Example:
+% \exampleindent
+% \begin{verbatim}
+%     \documentclass ...
+%     \usepackage{lhelp}
+%     \setcounter{excludelevel}{2}
+%     \begin{document}
+%     \includelower{1}{\input{some-xfig-figure.latex}}{}
+%     \includelower{2}{\includegraphics{some-image.eps}}{}
+% \end{verbatim}\fixendverbatim
+% Will include the xfig figure but not the eps image.
+% 
+% Set |excludelevel| to a number larger than the largest \meta{includelevel}
+% used to include everything.
+%
+% \DescribeMacro{\ifinclude}
+% An alternative to |\includelower| is
+% \begin{pckcmd}
+%     |\ifinclude{|\meta{includelevel}|}| \ldots\ |\else| \ldots\ |\fi|
+% \end{pckcmd}
+% |\ifinclude{|\meta{includelevel}|}| expands to |\iftrue| if
+% \meta{includelevel} is lower than the counter |excludelevel|, and |\iffalse|
+% otherwise.
+% 
+% 
+% \subsection{Including EPS files}
+% 
+% \DescribeMacro{\placeEPS}
+% This macro helps with inserting EPS files into the document, reducing the
+% amount of typing required for the common case. In draft mode (see package
+% option \option{epsdraft} below) only an outline of the EPS is drawn. Missing
+% files will not produce an error, only a warning is written on the screen.
+% \begin{pckcmd}
+%    |\placeEPS|\optmeta{moreargs}%^^A
+%       |{|\meta{width}|}{|\meta{height}|}{|\meta{filename}|}|
+% \end{pckcmd}
+%
+% Inserts encapsulated postsript file \meta{filename} into the text with width
+% \meta{width} and height \meta{height}. \meta{width} and/or \meta{height} may
+% be empty; default is natural size. \meta{moreargs} is anything that is allowed
+% as argument to |\includegraphics| (\package{graphicx} version), e.g. bounding
+% boxes---see the \package{graphicx} documentation.
+% 
+% The standard \package{graphicx} package is required, and must be loaded by the
+% user (\package{lhelp} does not load it). Unfortunately, \package{graphics} is
+% not sufficient, so that a document using |\placeEPS| must use the
+% \package{graphicx} package.
+% 
+% If \meta{filename} does not exist, an empty framed box with the given
+% dimensions is drawn with the name of the file in it; if any of \meta{width}
+% and \meta{height} are empty the default for \meta{width} is |.8\hsize|, and
+% for \meta{height} is |40mm|.
+%
+% In short, the advantages of |\placeEPS| over |\includegraphics| are:
+% \begin{itemize}
+% \item \ldots
+% \end{itemize}
+%
+% Example:\\
+%   \exampleindent
+%   |\placeEPS[bb=20 20 500 500,width=6cm]{}{5cm}{figure1}|\\
+% sets the bounding box to 20 20 500 500, and scales figure1.eps to a width of
+% 6\,cm and a height of 5\,cm.
+% The same could have been achieved with\\
+%   \exampleindent
+%   |\placeEPS[bb=20 20 500 500]{6cm}{5cm}{figure1}|
+%
+% \DescribeMacro{\addEPSopt}
+% \begin{pckcmd}
+%     |\addEPSopt{|\meta{options}|}|
+% \end{pckcmd}
+% |\addEPSopt| adds the given comma-separated \meta{options} to the internal
+% option list for |\placeEPS|, so that these options do not need to be repeated
+% with each |\placeEPS|. |\placeEPS| always passes the internal option list on
+% to |\includegraphics|.
+%
+% \DescribeOption{epsdraft}
+% With package option \option{epsdraft}, a draft keyword is inserted into every
+% |\placeEPS| to get only an outline-box of the eps (same as package option
+% \option{draft} for the \package{graphics} package).
+%
+% \DescribeOption{epspdf}
+% \DescribeMacro{\EPSfileext}
+% The package option \option{epspdf} sets |\EPSfileext| to \url{.eps}, or
+% \url{.pdf} when running under pdflatex. |\EPSfileext| is appended to the
+% filename by |\placeEPS|. This makes it possible to use |\placeEPS| in
+% documents which are compiled with either latex or pdflatex. The default for
+% |\EPSfileext| is empty, for compatibility with existing documents.
+%
+%
+% \subsection{List environments and aides}
+%
+% The following macros extend the functionality of the existing list
+% environments \env{list}, \env{itemize}, and \env{enumerate}.
+% 
+% First a few macros which set the spacing of a list environment. They are only
+% useful inside the second argument of the \env{list} environment, which is used
+% for setting various spacing-related variables.
+% 
+% \DescribeMacro{\listlabelleft}
+% Sets the horizontal spacing, and the label raggedright.
+% \begin{pckcmd}
+%     |\listlabelleft{|\meta{labelindent}|}{|\meta{labelwidth}|}{|%^^A
+%        \meta{labelsep}|}{|\meta{rightmargin}|}|
+% \end{pckcmd}
+% \meta{labelindent} is
+% the distance from the left edge of the surrounding text to the left edge of
+% the label, \meta{labelwidth} the width of the label, \meta{labelsep} the
+% distance between the label and the left edge of the list-text, and
+% \meta{rightmargin} the distance between the right edge of the list-text and
+% the right edge of the surrounding text.
+% 
+% \meta{labelindent}, \meta{labelwidth}, \meta{labelsep}, the width of the
+% list-text and \meta{rightmargin} added together make up |\columnwidth|. I find
+% this much more user-friendly than the way \LaTeX\ measures the horizontal
+% dimensions in the \env{list} environment.
+% |\listparindent| is set to zero.
+% Currently, |\itemindent| is unchanged but \LaTeX's default is zero.
+%
+% \DescribeMacro{\listlabelleftindent}
+% Some hard-coded values:
+% \begin{pckcmd}
+%     |\listlabelleftindent{|\meta{labelwidth}|}|
+% \end{pckcmd}
+% Short for |\listlabelleft{1.5em}{|\meta{labelwidth}|}{1.5em}{4.5em}|.
+% 
+% \DescribeMacro{\listshort}
+% |\listshort| sets all vertical spacing to zero: |\topsep|, |\partopsep|,
+% |\itemsep| and |\parsep|. Useful for lists which are not intended to stand out
+% as prominently as \LaTeX's default.
+% 
+% 
+% \DescribeEnv{Eenumerate}
+% \DescribeEnv{Eitemize}
+% Extend the \env{enumerate} and \env{itemize} environments such that the list
+% spacing can be user-controlled.
+% \begin{pckcmd}
+%     |\begin{Eenumerate}{|\meta{formatting for list}|}|\\
+%     |\begin{Eitemize}{|\meta{formatting for list}|}|
+% \end{pckcmd}
+% When \env{enumerate} and \env{itemize} call the \env{list} environment,
+% \meta{formatting for list} is inserted into the second argument of the
+% \env{list} environment to allow changing any of the spacing.
+% These can be mixed with \env{enumerate} and \env{itemize}.
+%
+% \DescribeEnv{enumerateshort}
+% \DescribeEnv{itemizeshort}
+% As the \env{enumerate} and \env{itemize} environments, but with reduced
+% vertical spacing.
+% \begin{pckcmd}
+%     |\begin{enumerateshort}|\\
+%     |\begin{itemizeshort}|
+% \end{pckcmd}
+% These can be mixed with \env{enumerate} and \env{itemize}.
+% 
+% 
+% \subsection{Starting new pages}
+% 
+% This macros start new pages in a variety of ways.
+% 
+% \DescribeMacro{\newoddpage}
+% \DescribeMacro{\newevenpage}
+% |\newoddpage| starts a new odd page and |\newevenpage| starts a new even page,
+% creating a blank page if necessary. The behaviour is always the same,
+% regardless whether the document is double-sided (i.e. |\twoside| is in effect)
+% or not.
+% 
+% \DescribeMacro{\clearoddpage}
+% \DescribeMacro{\clearevenpage}
+% |\clearoddpage| and |\clearevenpage| are the same as |\newoddpage| and
+% |\newevenpage|, except they call |\clearpage| first, causing all unprocessed
+% floats to be written out.
+% 
+% \DescribeMacro{\newoddpage*}
+% \DescribeMacro{\newevenpage*}
+% The star-form of these commands will always advance to the next odd/even page,
+% creating blank pages if necessary, even if the current page is odd/even and
+% empty. This means that they can be used repeatedly in immediate succession:
+% |\newoddpage*||\newoddpage*| starts an odd page and leaves another 2 blank
+% pages.
+% 
+% \DescribeMacro{\clearthispage}
+% |\clearthispage| writes out all unprocessed floats, and starts a new page
+% regardless of whether the current page is empty.
+% 
+% Currently none of these macros allow to change the pagestyle of any blank
+% pages which are generated (for example to empty when the document's pagestyle
+% is plain).
+% 
+% There could be problems with page number references after |\new...|. It might
+% pay to check |\pageref|'s after any of |\new...|.
+% 
+% 
+% \subsection{One and two columns}
+% 
+% \DescribeMacro{\ensureonecolumn}
+% \DescribeMacro{\ensuretwocolumn}
+% \DescribeMacro{\ensurecolumnend}
+% Ensure one or two columns for a part of a document, regardless
+% whether the rest of the document is in one or two columns. Every
+% |\ensureonecolumn|, or |\ensuretwocolumn| must be ended by
+% |\ensurecolumnend|.
+% \begin{pckcmd}
+%     |\ensureonecolumn|\\
+%     |\ensuretwocolumn|\\
+%     |\ensurecolumnend|
+% \end{pckcmd}
+% 
+% If nesting is required, the environment form must be used:
+% \begin{verbatim}
+%     ... text in one or two columns ...
+%     \begin{ensureonecolumn}
+%        ... text in one column ...
+%        \begin{ensuretwocolumn}
+%        ... text in two columns ...
+%        \end{ensuretwocolumn}
+%        ... text back in one column ...
+%     \end{ensureonecolumn}
+%     ... text in one or two columns again ...
+% \end{verbatim}\fixendverbatim
+% 
+% 
+% \subsection{Hanging indentation}
+% \label{s:hanghere}
+%
+% \DescribeMacro{\hanghere}
+% The macro |\hanghere| causes a hanging indentation for the rest of the
+% paragraph, from the actual horizontal position of the |\hanghere|.
+% 
+% \emph{NOTE: The code for \texttt{\string\absval} and
+% \texttt{\string\hangindent} is not covered by the copyright of the
+% \package{lhelp} package, and, as published by its author, remains without
+% copyright.}
+% 
+% Here is the documentation of |\hanghere|, as published on the newsgroup
+% \url{comp.text.tex}:
+% 
+% \begin{verbatim}
+% -- Donald Arseneau (1993)  (Not copyright, not supported)
+%    asnd@reg.triumf.ca
+%
+% This is a style file that can be used in both LaTeX and plain TeX.
+% To use, put \hanghere in the middle of a paragraph and the rest of 
+%             the paragraph will be indented to the spot so indicated.
+%             Spaces are retained on both sides of \hanghere, but if
+%                                                  you want a space 
+%                                                  afterwards, you 
+%                                                  should type \hanghere\ 
+% or \hanghere{} .  There is a length parameter, \minlinelen, that sets
+%    a minimum length for the lines of text.  If the position of \hanghere
+% would cause the line length to be too small, the following lines will
+% start at the left margin, as illustrated twice just above. Multiple
+% uses of \hanghere in a paragraph are cumulative, until the line length
+%         gets too short and reverts to the full text width.  There are
+%         no parboxes used so line spacing and page breaking is normal.
+%         There is one problem: if some text on the first line following
+%         the \hanghere is very tall, it can overlap the text above 
+%             instead of doing the line spacing properly.  Other instances
+%             of tall text work fine.
+% \end{verbatim}\fixendverbatim
+%
+% \DescribeMacro{\absval}
+% The |\absval| macro is used by |\hanghere|, but is generally useful. It
+% returns the ``absolute value of a number or a dimension (if in a dimension
+% register)''.
+%
+% \DescribeMacro{\labelhangindent}
+% Hanging indentation with the width of the printed label.
+% \begin{pckcmd}
+%     |\labelhangindent{|\meta{label}|}|
+% \end{pckcmd}
+% This prints \meta{label} and starts a hanging indentation.
+% The hanging indentation remains for all paragraphs in the current group.
+% Because this does not insert any horizontal space after the label, it is
+% probably a good idea to insert a \verb*'\ ' as part of the label.
+% |\labelhangindent| uses |\everypar|.
+% So far, |\labelhangindent| is not cumulative, i.e. only one can be used in a
+% paragraph.
+%
+%
+% \subsection{Misc}
+% 
+% \DescribeMacro{\gobble}
+% \DescribeMacro{\gobbletwo}
+% These macros simply discard their argument(s).
+% \begin{pckcmd}
+%     |\gobble{|\meta{anything}|}|\\
+%     |\gobbletwo{|\meta{anything}|}{|\meta{anythingelse}|}|
+% \end{pckcmd}
+%
+%
+% \DescribeOption{ddmonthyyyy}
+% \DescribeMacro{\ddmonthyyyy}
+% Package option \option{ddmonthyyyy} switches |\today|'s date format to a more
+% user-friendly (and non-American) ``dd Month yyyy''. Regardless of what
+% |\today| happens to be defined as, |\ddmonthyyyy| gives a format of
+% \ddmonthyyyy.
+%
+%
+% \DescribeOption{yyyymmdd}
+% \DescribeMacro{\yyyymmdd}
+% Package option \option{yyyymmdd} switches |\today|'s date format to
+% ``yyyy/mm/dd''. Regardless of what |\today| happens to be defined as,
+% |\yyyymmdd| gives a format of \yyyymmdd.
+%
+%
+% \DescribeOption{hh:mm}
+% \DescribeMacro{\timehhmm}
+% \DescribeMacro{\todayaddtime}
+% The current time is put into |\timehhmm| formatted as HH:MM with leading 0.
+% Package option \option{hh:mm} appends |\timehhmm| to whatever |\today| is
+% defined as, at the beginning of the document. Order of options is
+% important---\option{yyyymmdd} for example redefines |\today|, so an appended
+% time would be lost. |\todayaddtime| appends the time to the definition of
+% |\today|, which is useful if something else has redefined |\today|.
+% 
+% 
+% \DescribeOption{morefontsizes}
+% Package option \option{morefontsizes} defines the additional font sizes
+% |\HUGE|, |\veryhuge|, |\veryHuge|, and |\veryHUGE|, which is sometimes useful
+% for posters, or very large headings. It should look ok with PostScript fonts,
+% and perhaps computer modern fonts. It is recommended to use this with the
+% type-1 version of the computer modern fonts, or metafont might create some
+% humungous bitmap fonts.
+%
+%
+% \DescribeOption{verbose}
+% Package option \option{verbose} causes some commands to print some
+% output which might be useful sometimes. Currently only |\placeEPS| makes use
+% of it.
+%
+%
+% \DescribeOption{shorttoc}
+% For documents with a zero |\parindent| and a non-zero |\parskip|,
+% |\tableofcontents| generates fairly useless output.  Package option
+% \option{shorttoc} restores the previous behaviour for the table of contents.
+%
+%
+% \DescribeOption{countryselect}
+% \DescribeMacro{\selectD}
+% \DescribeMacro{\selectNZ}
+% \DescribeMacro{\selectUK}
+% \DescribeMacro{\selectUSA}
+% These macros are meant to provide a standardised way for selecting
+% country-specific settings, i.e.\ hyphenation patterns and 
+% specific language definitions. Theoretically, the \package{babel}
+% package should offer this, but it doesn't---the name for a particular country
+% depends on the name entered into \package{babel}'s configuration file, for
+% which there is no standard. Package option \option{countryselect} defines
+% known names for selecting settings of a specific country.
+% Because using the hyphenation patterns of a language is desirable even
+% without the language-specific macro definitions, these commands now select
+% the hyphenation patterns when available, even if babel is not used by the
+% document. If babel is used, a |\selectlanguage| command is issued.
+% 
+% Currently only \package{babel} is supported as underlaying language-switching
+% mechanism. Clearly this also calls for an \package{lhelp} configuration file,
+% matching the entries in \package{babel}'s.
+% 
+% So far, |\selectD|, |\selectNZ|, |\selectUK|, |\selectUSA| are
+% defined for Germany, New Zealand, the UK, and the USA.
+% 
+% 
+% \DescribeEnv{narrowpars}
+% The narrowpars environment temporarily narrows the width of the text body,
+% respectively increases the left and right margins.
+% \begin{pckcmd}
+%     |\begin{narrowpars}{|\meta{indentation}|}|
+% \end{pckcmd}
+% Paragraphs are narrowed by \meta{indentation} on the left and
+% \meta{indentation} on the right.
+% It uses |\everypar|, |\hangindent| and |\hangafter|, and changes
+% |\columnwidth| and |\hsize|.
+% 
+% It would have been possible to achieve the same effect by using |\leftskip|
+% and |\rightskip|, but either will fail in some cases. Perhaps a narrowpars$*$
+% environment should use these?
+%
+%
+% \DescribeMacro{\thinthinspace}
+% Approximately half a thinspace. A quarterspace?
+%
+%
+% \DescribeMacro{\setTBstruts}
+% \DescribeMacro{\T}
+% \DescribeMacro{\B}
+% In tables created with tabular and array which use horizontal lines, there is
+% often too little space between the text of a line and the adjacent horizontal
+% lines. |\setTBstruts| defines two macros, |\T| and |\B|, which fine-tune the
+% vertical spacing on these lines.
+% Example:
+%
+% \begin{minipage}[t]{.38\textwidth}
+% \vspace{-2ex}
+% \begin{verbatim}
+%     text ...\par
+%     \setTBstruts
+%     \begin{tabular}{ll}
+%         \hline\T
+%             cell$^2$ & cell\\
+%             cell$_3$ & cell \B\\
+%         \hline\T
+%             cell & cell \B\\
+%         \hline
+%     \end{tabular}\par
+%     text ...
+% \end{verbatim}%^^A\fixendverbatim
+% \end{minipage}\hspace{8mm}
+% \begin{minipage}[t]{.2\textwidth}
+%     With |\T| and |\B|:\\[1ex]
+%     text ...\par
+%     \setTBstruts
+%     \begin{tabular}{ll}
+%         \hline\T
+%             cell$^2$ & cell\\
+%             cell$_3$ & cell \B\\
+%         \hline\T
+%             cell & cell \B\\
+%         \hline
+%     \end{tabular}\par
+%     text ...
+% \end{minipage}\hspace{8mm}
+% \begin{minipage}[t]{.15\textwidth}
+%     Without:\\[1ex]
+%     text ...\par
+%     \begin{tabular}{ll}
+%         \hline
+%             cell$^2$ & cell\\
+%             cell$_3$ & cell\\
+%         \hline
+%             cell & cell\\
+%         \hline
+%     \end{tabular}\par
+%     text ...
+% \end{minipage}
+%
+% (Taken from "TeX and TUG NEWS", Vol. 2, No. 3, 1993, p. 10.)
+%
+%
+% \DescribeMacro{\placepos}
+% This macro can place anything at an arbitrary position onto the page, without
+% shifting the current position (as much that is possible).
+% \begin{pckcmd}
+%	|\placepos{|\meta{right}|}{|\meta{down}|}{|\meta{text}|}|
+% \end{pckcmd}
+% Places \meta{text} (in LR mode) a distance of \meta{right} to the right and
+% \meta{down} down from the current position. \meta{right}, \meta{down} can be
+% negative.
+%
+% |\placepos{..}| has zero size and is equivalent to |\hbox{}|, which is the
+% same as |\mbox{}| without the |\leavevmode|. This means that |\placepos|,
+% unlike |\mbox|, will never start a paragraph. Although |\placepos| has zero
+% size, placing an |\hbox| can have effects on spacing in some circumstances.
+% If |\placepos| is at the beginning of a paragraph of text, it 
+% might be necessary to use a |\leavevmode| before the first |\placepos|.
+%
+% To include paragraph material in \meta{text}, use
+% |\parbox{|\meta{width}|}{|\meta{text}|}| as \meta{text}.
+%
+% Spaces following |\placepos| are ignored.
+%
+%
+% \DescribeMacro{\PSadjust}
+% Some older versions of the PostScript fonts had such a tight horizontal
+% spacing that they could essentially not hyphenate a word. As a temporary
+% solution it was suggested to change some line breaking parameters. Putting
+% |\PSadjust| into the preamble will do this.
+% Current versions of the PostScript fonts (from CTAN) don't need this.
+%

+% \section{To Do and Bugs}
+%
+% To do:
+% \begin{itemizeshort}
+% \item
+% 	|\sref| should become |\aref| when used after |\appendix|
+% \item
+% 	coloured boxes of specified sizes, e.g. |\fcolorparbox|
+% \item
+%	Provide an upright Greek micro for units in roman text.
+% \end{itemizeshort}
+% 
+% Any bugs? 
+% Please notify the author if you find any, or if the documentation is unclear.
+% These ones were already found:
+% \begin{itemizeshort}
+% \item
+% 	draftmarkps causes two DRAFT warnings to be printed and logged to .log,
