+% \begin{abstract}
+%    The \Lpack{verse} package provides some aids for the typesetting
+% of simple verse.

+%
+% 
+%
+% \section{Introduction}
+%
+% The typesetting of a poem should be really be dependent on the
+% particular poem. Individual problems do not usually admit of a
+% general solution, so this document and code should be used more
+% as a guide towards some solutions rather than providing a ready
+% made solution for any particular piece of verse.
+%
+% This manual is typeset according to the conventions of the
+% \LaTeX{} \textsc{docstrip} utility which enables the automatic
+% extraction of the \LaTeX{} macro source files~\cite{GOOSSENS94}.
+%
+%    Section~\ref{sec:usc} describes the usage of the \Lpack{verse} 
+% package and 
+% commented source code is in Section~\ref{sec:code}.
+%
+% The doggerel used as illustrative material has been taken 
+% from~\cite{RUMOUR}.
+%
+% LaTeX provides the |verse| environment which is defined as a particular
+% kind of list. Within the environment you use |\\| to end a line
+% and a blank line will end a stanza. For example, here is a single
+% stanza poem:
+% \begin{verbatim}
+% \newcommand{\garden}{
+% I used to love my garden \\
+% But now my love is dead \\
+% For I found a bachelor's button \\
+% In black-eyed Susan's bed.
+% }
+% \end{verbatim}
+% \newcommand{\garden}{
+% I used to love my garden \\
+% But now my love is dead \\
+% For I found a bachelor's button \\
+% In black-eyed Susan's bed.
+% }
+% When this is typeset as a normal LaTeX paragraph (with no paragraph
+% indentation) it looks like: \\[\baselineskip]
+% \garden{}
+%
+% \ablankline
+%
+%    Typesetting it within the |verse| environment produces: \\[\baselineskip]
+% \begin{verse}  
+% \garden
+% \end{verse}
+%
+% \ablankline
+%
+% The stanza could also be typeset within the |alltt| environment, defined
+% in the standard \Lpack{alltt} package, using a normal font and no |\\|
+% line endings.
+% \begin{verbatim}
+% \begin{alltt}\normalfont
+% I used to love my garden 
+% But now my love is dead 
+% For I found a bachelor's button 
+% In black-eyed Susan's bed.
+% \end{alltt}
+% \end{verbatim}
+% which produces:
+% \begin{alltt}
+% \normalfont
+% I used to love my garden 
+% But now my love is dead 
+% For I found a bachelor's button 
+% In black-eyed Susan's bed.
+% \end{alltt}
+% The |alltt| environment is like the |verbatim| environment except that
+% you can use LaTeX macros inside it. Note that the \% characters are
+% an artifact of an interaction between this document's class and
+% the |alltt| environment that I have not been able to eliminate.
+%
+%    In the |verse| environment long lines will be wrapped and indented
+% but in the |alltt| environment there is no indentation. 
+%
+% Some stanzas have certain lines indented, often alternate ones. To
+% typeset stanzas like this you have to add your own spacing. For
+% instance:
+% \begin{verbatim}
+% \begin{verse}
+% There was an old party of Lyme \\
+% Who married three wives at one time. \\
+% \hspace{2em} When asked: `Why the third?' \\
+% \hspace{2em} He replied: `One's absurd, \\
+% And bigamy, sir, is a crime.'
+% \end{verse}
+% \end{verbatim}
+% will be typeset in a verse environment as: 
+% \begin{verse}
+% There was an old party of Lyme \\
+% Who married three wives at one time. \\
+% \hspace{2em} When asked: `Why the third?' \\
+% \hspace{2em} He replied: `One's absurd, \\
+% And bigamy, sir, is a crime.'
+% \end{verse}
+%
+% \ablankline
+%
+% Using the |alltt| environment you can put in the spacing via ordinary
+% spaces. That is, this
+% \begin{verbatim}
+% \begin{alltt}\normalfont
+% There was an old party of Lyme
+% Who married three wives at one time.
+%       When asked: `Why the third?' 
+%       He replied: `One's absurd, 
+% And bigamy, sir, is a crime.'
+% \end{alltt}
+% \end{verbatim}
+% is typeset as
+% \begin{alltt}
+% \normalfont
+% There was an old party of Lyme
+% Who married three wives at one time.
+%       When asked: `Why the third?' 
+%       He replied: `One's absurd, 
+% And bigamy, sir, is a crime.'
+% \end{alltt}
+%
+% More exotically you could use the TeX |\parshape| command:
+% \begin{verbatim}
+% \parshape = 5 0pt \linewidth 0pt \linewidth 
+%               2em \linewidth 2em \linewidth 0pt \linewidth
+% \noindent There was an old party of Lyme \\
+% Who married three wives at one time. \\
+% When asked: `Why the third?' \\
+% He replied: `One's absurd, \\
+% And bigamy, sir, is a crime.' \par
+% \end{verbatim}
+% which will be typeset as:
+%
+% \ablankline
+%
+% \parshape = 5 0pt \linewidth 0pt \linewidth 
+%               2em \linewidth 2em \linewidth 0pt \linewidth
+% \noindent There was an old party of Lyme \\
+% Who married three wives at one time. \\
+% When asked: `Why the third?' \\
+% He replied: `One's absurd, \\
+% And bigamy, sir, is a crime.' \par
+%
+% \ablankline
+% 
+%    This is about as much assistance as standard (La)TeX provides.
+%

+% \clearpage
+% \section{The \Lpack{verse} package} \label{sec:usc}
+%
+% The code provided by the \Lpack{verse} package is meant to help
+% with some aspects of typesetting poetry but does not, and cannot,
+% provide a comprehensive solution to all the requirements that
+% will arise.
+%
+% \DescribeEnv{verse}
+% The |verse| environment provided by the package is an extension
+% of the usual LaTeX environment. The environment takes one optional
+% parameter, which is a length; for example |\begin{verse}[4em]|.
+% You may have noticed that the earlier verse examples are all
+% near the left margin, whereas verses usually look better if they
+% are typeset about the center of the page. The length parameter,
+% if given, should be about the length of an average line, and then
+% the entire contents will be typeset with the mid point of the length
+% centered horizontally on the page.
+%
+% \DescribeMacro{\versewidth}
+% The length |\versewidth| is provided as a convenience. It may be used,
+% for example, to calculate the length of a line of text for use
+% as the optional argument to the |verse| environment: 
+% \begin{verbatim}
+% \settowidth{\versewidth}{This is the average line,}
+% \begin{verse}[\versewidth]
+% \end{verbatim}
+%
+% \DescribeEnv{altverse}
+% Within the |verse| environment verses are seperated by a blank line
+% in the input. Individual verses within |verse| may, however, 
+% be enclosed in the |altverse| environment. This has the effect of
+% indenting the 2nd, 4th, etc., lines of the verse by the length |\vgap|.
+%
+% \DescribeEnv{patverse}
+% Individual verses within the |verse| environment may be enclosed
+% in the |patverse| environment. Within the environment the indentation
+% of each line is specified by an indentation pattern, which consists
+% of an array of digits, $d_{1}$ to $d_{n}$, and the $n^{th}$ line is
+% indented by $d_{n}$ times |\vgap|. However, the first line is
+% not indented, irrespective of the value of $d_{1}$.
+%
+% \DescribeEnv{patverse*}
+% The |patverse*| environment is similar to |patverse| environment,
+% except that the pattern will keep on repeating itself.
+%
+% \DescribeMacro{\indentpattern}
+% The indentation pattern for a |patverse| environment is specified
+% via the |\indentpattern{|\meta{digits}|}| command. If the pattern is
+% shorter than the number of lines in a verse, the trailing lines will
+% not be indented.
+%
+% \DescribeMacro{\vin}
+% \DescribeMacro{\vgap}
+% The command |\vin| is shorthand for |\hspace{\vgap}| for use
+% at the start of an indented line of verse. The length |\vgap|
+% (initially 1.5em) can be changed by |\setlength| or |\addtolength|.
+%
+% \DescribeMacro{\vindent}
+% When a verse line is too long to fit within the typeblock it is
+% wrapped onto the next line with a space, given by the value of the
+%
+% \DescribeMacro{\stanzaskip}
+% The length |\stanzaskip| controls the spacing between stanzas.
+% It may be changed like any other length.
+%
+% \DescribeMacro{\verselinebreak}
+% Using the command |\verselinebreak[|\meta{length}|]| will cause 
+% later text in the
+% line of the verse to be typeset indented on the following line.
+% If the optional length argument is not given the indentation is 
+% |\vgap|, otherwise the indentation is given by \meta{length} plus |\vgap|.
+% The broken
+% line will count as a single line as far as the |altverse| and |patverse|
+% environments are concerned (see also the |\\>| macro).
+%
+% \DescribeMacro{\flagverse}
+% \DescribeMacro{\vleftskip}
+% Putting the command |\flagverse{|\meta{flag}|}| at the start of a line
+% of verse will typeset \meta{flag} towards the left margin, ending
+% a distance |\vleftskip| before the verse line.
+%
+% \DescribeMacro{\poemlines}
+% The declaration |\poemlines{|\meta{nth}|}| will cause every \meta{nth}
+% lines of succeeding verses to be numbered. For example, |\poemlines{5}|
+% will number every fifth line. The default is |\poemlines{0}| which prevents
+% any numbering.
+%
+% \DescribeMacro{\thepoemline}
+% \DescribeMacro{\vrightskip}
+% Lines are numbered via |\thepoemline| which defaults to typesetting normal
+% sized arabic numerals. These are typeset at the distance |\vrightskip| into
+% the right margin.
+%
+% \DescribeMacro{\\}
+% Within the |verse| environment, the macro |\\| must be used at the
+% end of each line of a verse, except for the last line in each stanza.
+% If the lines in a poem are to be numbered then |\\!| must be used at the 
+% end of the last line in each stanza (the |\\| macro increments the line
+% numbers). The starred version, |\\*|, prohibits a page break after the
+% line. The |\\>| version causes a linebreak within a verse line.
+% The |\\| macro in its various forms can also take an optional length 
+% argument, like |\\[30pt]|
+% which will insert |30pt| of vertical space; in the case of |\\>[30pt]|
+% an additional 30pt of horizontal space will be inserted after the
+% linebreak (effectively |\\>| is shorthand for |\verselinebreak|).
+% The allowable forms of the
+% macro are: |\\|, |\\*|. |\\!|, |\\>|, |\\[...]|, |\\*[...]|, |\\![...]|,
+% and |\\>[...]|.
+%
+% \DescribeMacro{\label}
+% \DescribeMacro{\ref}
+% The standard |\label{|meta{key}|}| command
+% can be used inside the |verse| environment, between the end of the text 
+% of a line and the line-ending |\\|, to grab that line number, no matter 
+% what the setting of |\poemlines|. Elsewhere the standard
+% |\ref{|\meta{key}|}| command can be used to refer to the line number.
+%
+% \DescribeMacro{\poemtitle}
+% |\poemtitle[|\meta{short}|}{|\meta{long}|}| typesets the title
+% of a poem and makes an entry into the ToC. There is a starred version
+% that makes no ToC entry.
+%
+% \DescribeMacro{\poemtoc}
+% The kind of entry made in the ToC by the |\poemtitle| command is
+% defined by |\poemtoc|. The initial definition is: \\
+% |\newcommand{\poemtoc}{section}| \\
+% for a section-like ToC entry. This can be changed to, say, |chapter|
+% or |subsection| or \ldots.
+%
+% \DescribeMacro{\poemtitlefont}
+% This macro specifies the font and positioning of the poem title. Its
+% initial definition is: \\
+% |\newcommand{\poemtitlefont}{\normalfont\bfseries\large\centering}| \\
+% to give a |\large| bold centered title. This can of course be renewed
+% if you want something else.
+%
+% \DescribeMacro{\beforepoemtitleskip}
+% \DescribeMacro{\afterpoemtitleskip}
+% These two lengths are the vertical space before and after the |\poemtitle|
+% title text. They are initially defined to give the same spacing
+% as for a |\section| title. They can be changed by |\setlength| or
+% |\addtolength| for different spacings.
+%
+%
+% \DescribeMacro{\poemtitlemark}
+% The |\poemtitle| macro, but not |\poemtitle*|,
+% calls the |\poemtitlemark{|\meta{title}|}| macro,
+% which is defined to do nothing. This would probably be changed by a
+% pagestyle definition (like |\sectionmark| or |\chaptermark|).
+%
+% \subsection{Supports}
+%
+%    The package includes some macros for supporting the |patverse|
+% environment which may be more generally useful. See the code section
+% for examples on how these may be used.
+%
+% \DescribeMacro{\newarray}
+% |\newarray{|\meta{arrayname}|}{|\meta{low}|}{|\meta{high}|}| defines
+% the \meta{arrayname} array, where \meta{arrayname} is a name like
+% |MyArray|. The lowest and highest array indices are set to
+% \meta{low} and \meta{high} respectively, where both are integer numbers.
+%
+% \DescribeMacro{\setarrayelement}
+% |\setarrayelement{|\meta{arrayname}|}{|\meta{index}|}{|\meta{text}|}|
+% sets the \meta{index} location in the \meta{arrayname} array to be 
+% \meta{text}. For example: \\
+%  |\setarrayelement{MyArray}{23}{$2^{23}$}|.
+%
+% \DescribeMacro{\getarrayelement}
+% |\getarrayelement{|\meta{arrayname}|}{|\meta{index}|}{|\meta{result}|}|
+% sets the parameterless macro \meta{result} to the contents of
+% the \meta{index} location in the \meta{arrayname} array. For
+% example: \\
+%  |\getarrayelement{MyArray}{23}{\result}|.
+%
+% \DescribeMacro{\checkarrayindex}
+% |\checkarrayindex{|\meta{arrayname}|}{|\meta{index}|}| checks if
+% \meta{arrayname} is an array and if \meta{index} is a valid index for
+% the array.
+%
+% \DescribeMacro{\stringtoarray}
+% |\stringtoarray{|\meta{arrayname}|}{|\meta{string}|}| puts each character
+% from \meta{string} sequentially into the \meta{arrayname} array, starting
+% at index 1. For example: \\
+%  |\stringtoarray{MyArray}{Chars}|.
+%
+% \DescribeMacro{\arraytostring}
+% The macro |\arraytostring{|\meta{arrayname}|}{|\meta{result}|}| assumes
+% that \meta{arrayname} is an array of characters, and defines the macro
+% \meta{result} to be that sequence of characters. For example: \\
+% |\arraytostring{MyArray}{\MyString}|.
+%
+% \DescribeMacro{\checkifinteger}
+% |\checkifinteger{|\meta{num}|}| ckecks if \meta{num} is an integer (not less
+% than zero). If it is then |\ifinteger| is set TRUE, otherwise it is set 
+% FALSE.
+%
+% \clearpage
+% \subsection{Examples}
+%
+%    Here are some sample verses using the package facilities.
+% First our old Limerick friend, but titled and centered:
+% \begin{verbatim}
+% \renewcommand{\poemtoc}{subsection}
+% \poemtitle{A Limerick}
+% \settowidth{\versewidth}{There was an old party of Lyme}
+% \begin{verse}[\versewidth]
+% There was an old party of Lyme \\
+% Who married three wives at one time. \\
+% \vin When asked: `Why the third?' \\
+% \vin He replied: `One's absurd, \\
+% And bigamy, sir, is a crime.'
+% \end{verse}
+% \end{verbatim}
+% which gets typeset as below. The default |\poemtoc| is redefined
+% to |subsection| so the
+% title is entered into the ToC as an unnumbered |\subsection|.
+%
+% \renewcommand{\poemtoc}{subsection}
+% \poemtitle{A Limerick}
+% \settowidth{\versewidth}{There was an old party of Lyme}
+% \begin{verse}[\versewidth]
+% There was an old party of Lyme \\
+% Who married three wives at one time. \\
+% \vin When asked: `Why the third?' \\
+% \vin He replied: `One's absurd, \\
+% And bigamy, sir, is a crime.'
+% \end{verse}
+%
+% \ablankline
+%
+%     Next is the Garden verse within the |altverse| environment. It
+% is titled and centered.
+% \begin{verbatim}
+% \settowidth{\versewidth}{But now my love is dead}
+% \poemtitle{Love's lost}
+% \begin{verse}[\versewidth]
+% \begin{altverse}
+% \garden
+% \end{altverse}
+% \end{verse}
+% \end{verbatim}
+% which produces:
+% \settowidth{\versewidth}{But now my love is dead}
+% \poemtitle{Love's lost}
+% \begin{verse}[\versewidth]
+% \begin{altverse}
+% \garden
+% \end{altverse}
+% \end{verse}
+%
+%  \ablankline
+%
+% It is left up to you how you might want to add information about
+% the author of a poem. Here is one example of a macro for this:
+% \begin{verbatim}
+% \newcommand{\attrib}[1]{%
+%    \nopagebreak{\raggedleft\footnotesize #1\par}}
+% \end{verbatim}
+% \newcommand{\attrib}[1]{%
+%    \nopagebreak{\raggedleft\footnotesize #1\par}}
+%
+%    This can be used as in the next bit of doggeral.
+% \begin{verbatim}
+% \poemtitle{Fleas}
+% \settowidth{\versewidth}{What a funny thing is a flea}
+% \begin{verse}[\versewidth]
+% What a funny thing is a flea. \\
+% You can't tell a he from a she. \\
+% But he can. And she can. \\
+% Whoopee!
+% \end{verse}
+% \attrib{Anonymous}
+% \end{verbatim}
+%
+% \poemtitle{Fleas}
+% \settowidth{\versewidth}{What a funny thing is a flea}
+% \begin{verse}[\versewidth]
+% What a funny thing is a flea. \\
+% You can't tell a he from a she. \\
+% But he can. And she can. \\
+% Whoopee!
+% \end{verse}
+% \attrib{Anonymous}
+%
+% \ablankline
+%
+% Here is an example of line wrapping.
+% \begin{verbatim}
+% \poemtitle{In the beginning}
+% \settowidth{\versewidth}{And objects at rest tended to remain at rest}
+% \begin{verse}[\versewidth]
+% Then God created Newton, \\
+% And objects at rest tended to remain at rest, \\
+% And objects in motion tended to remain in motion, \\
+% And energy was conserved
+%    and momentum was conserved
+%    and matter was conserved \\
+% And God saw that it was conservative.
+% \end{verse}
+% \attrib{Possibly from \textit{Analog}, circa 1950}
+% \end{verbatim}
+%
+% \enlargethispage{\baselineskip}
+% \poemtitle{In the beginning}
+% \settowidth{\versewidth}{And objects at rest tended to remain at rest}
+% \begin{verse}[\versewidth]
+% Then God created Newton, \\

+% And objects in motion tended to remain in motion, \\
+% And energy was conserved
+%    and momentum was conserved
+%    and matter was conserved \\
+% And God saw that it was conservative.
+% \end{verse}
+% \attrib{Possibly from \textit{Analog}, circa 1950}
+%
+% \ablankline
+%
+% Here is one with a forced line break and a slightly different title style.
+% \begin{verbatim}
+% \renewcommand{\poemtitlefont}{\normalfont\large\itshape\centering}
+% \poemtitle{Mathematics}
+% \settowidth{\versewidth}{Than Tycho Brahe, or Erra Pater:}
