+% \begin{abstract}
+%  The \packagename{asypictureB} package allows users to integrate Asymptote code 
+%  for producing pictures into \LaTeX\ source code using the shell-escape 
+%  functionality. It is an alternative to the \texttt{asymptote} package 
+%  that comes with Asymptote. The most important advantage of the 
+%  \packagename{asypictureB} package is that it provides immediate access to 
+%  Asymptote errors by repackaging them as \LaTeX\ errors. It also allows 
+%  limited use of TeX macros such as |\the\linewidth| inside Asymptote code.
+% \end{abstract}
+% 
+% \noindent\textbf{Disclaimer:} The author of this package has no affiliation with 
+% the creators of the Asymptote programming language.

+% 
+% \section{Introduction}
+% 
+% The \href{http://asymptote.sourceforge.net}%
+% {Asymptote programming language}\footnote{\url{http://asymptote.sourceforge.net}} 
+% is a powerful tool for the creation of diagrams, both two- and
+% three-dimensional, that are compatible with 
+% \TeX\ documents. The programming language ships with a \LaTeX\ package 
+% called (appropriately but confusingly) \packagename{asymptote} that makes it 
+% easy to draw pictures by including Asymptote code in the \LaTeX\ source 
+% file. The \packagename{asymptote} package also allows the inclusion of 
+% interactive three-dimensional images in |pdf| files.\footnote{ 
+% The \packagename{asypictureB} package does not 
+% currently support this feature.}
+% 
+% Unfortunately, the author has encountered the several annoyances 
+% using the \packagename{asymptote} package.
+% \begin{enumerate}
+% \item
+% When my Asymptote code contains errors that prevent it 
+% from compiling, I have found it extremely difficult to track down 
+% the offending line in the \TeX\ source file. This has been the 
+% single biggest annoyance and has led me to compose all but the simplest 
+% Asymptote images as separate |.asy| files, which are then 
+% included into the \TeX\ source once they do what I want.
+% \item 
+% The \packagename{asymptote} package does not support PNG files, 
+% although the Asymptote language does.\footnote{A note 
+% on why this is desirable: Asymptote's 3d capabilities are 
+% currently much better for 
+% rasterized images than for vector graphics. Thus, it is often desirable 
+% to produce a rasterized image. Because of a quirk of Asymptote, it is 
+% easy to produce high-resolution images in PNG format, but much harder 
+% to raise the resolution when the output is in the default PDF format.}
+% \item
+% The \packagename{asymptote} package does have a mechanism in place so that 
+% when it is used with |latexmk|, Asymptote images that have not changed are 
+% not recompiled. Unfortunately, the mechanism for recognizing unchanged images 
+% is somewhat fragile: if a single image is inserted or deleted, then all 
+% subsequent images will have to be recompiled. In my experience, this can 
+% make a compilation last several minutes that would otherwise have lasted 
+% several seconds.
+% \item
+% The \packagename{asymptote} package can rescale an Asymptote-produced 
+% image to a given width and/or a given height, but it cannot rescale the 
+% image by a given scaling factor.\footnote{This is relevant because a 
+% second trick for producing a high-resolution rasterized image with the 
+% Asymptote language is to produce a scaled-up PDF image, and then 
+% scale it back down when including it into the \TeX\ file.}
+% \end{enumerate}
+% The most important issue here is the first, which can to some extent be fixed 
+% using editor features; see, for instance, 
+% \href{http://www.artofproblemsolving.com/Wiki/index.php/Asymptote:_Advanced_Configuration\#Showing_Asymptote_error_messages_in_TeXnicCenter}%
+% {this explanation for TeXnicCenter (Windows only)}\footnote{\raggedright
+% \url{http://www.artofproblemsolving.com/Wiki/index.php/Asymptote:_Advanced_Configuration\#Showing_Asymptote_error_messages_in_TeXnicCenter}
+% }.
+% 
+% The \packagename{asypictureB} package is an alternative to the 
+% \packagename{asymptote} 
+% package that (optionally) 
+% uses |\write18| to call the Asymptote compiler directly from 
+% \LaTeX. The package provides some sort of fix for 
+% all the above issues:
+% \begin{enumerate}
+% \item
+% Asymptote errors are repackaged as \LaTeX\ errors and reported immediately.
+% At a minimum, the user is shown the Asymptote error log and a line number 
+% that will allow him to locate the correct Asymptote picture within the 
+% \TeX\ source file.
+% 
+% Additionally, \packagename{asypictureB} is usually able to display the 
+% five lines of Asymptote code up to and including the first error. This is 
+% useful to locate the line of code 
+% on which the error occurs, since the line numbers in the Asymptote error log 
+% do not correspond to the line numbers in the \LaTeX\ source file.
+% %
+% \item
+% Any file type that is supported by both the Asymptote language and the 
+% |\includegraphics| command is supported by \packagename{asypictureB}. 
+% Assuming that the document is compiled using \texttt{pdflatex}, this includes 
+% the PNG, PDF, and (more or less) EPS file formats.
+% \item
+% Users are permitted and strongly encouraged to specify a distinct name for 
+% each Asymptote image in the file. Distinctly named Asymptote images 
+% are not recompiled if their 
+% code has not changed since the last |latex| run.
+% \item Any option that works for the |\includegraphics| command can be given 
+% as an option to an |asypicture| environment.
+% \end{enumerate}
+% 
+% There is one other feature worth mentioning: \LaTeX\ macros will be expanded 
+% inside Asymptote code if they are prefixed by @ instead of |\|. This 
+% can be used as an incomplete substitute for the |inline| option of the 
+% \packagename{asymptote} package.  It also provides a way to use macros 
+% in Asymptote code, which is not a feature that Asymptote supports otherwise.
+% 
+% Each of these features could stand significant improvements. However, 
+% since implementing them, the author has found himself much more willing 
+% to compose Asymptote code directly in a \TeX\ source file.  This indicates 
+% to him that the package might prove useful to others, even in its current 
+% form.  His hope is that the best ideas of this package would 
+% be copied and improved in the official \packagename{asymptote} package,
+% allowing him to deprecate \packagename{asypictureB}.
+% 
+% \section{Installation and running}
+% 
+% First of all, the \packagename{asypictureB} package is mostly useless unless you 
+% have Asymptote installed on your system. 
+% \begin{itemize}
+% \item For a Mac OS X system, this installation
+% is automatic with a standard installation 
+% of \href{http://tug.org/mactex/}{MacTeX}. 
+% \item For a Windows system, the 
+% \href{http://asymptote.sourceforge.net/doc/Microsoft-Windows.html}{official 
+% installation instructions} are fairly good. As of this writing, the most 
+% recent version of the |setup.exe| file can be downloaded from 
+% \url{http://sourceforge.net/projects/asymptote/files/2.24/}.
+% \item
+% For a Unix-like system, a version of 
+% Asymptote is included in TeX Live, but there may be additional dependencies;
+% see, for instance, \url{http://tex.stackexchange.com/a/155284/484}. You 
+% should also consult 
+% \href{http://asymptote.sourceforge.net/doc/UNIX-binary-distributions.html}{these}
+% \href{http://asymptote.sourceforge.net/doc/Compiling-from-UNIX-source.html}{two}
+% pages from the official documentation. 
+% \end{itemize}
+% 
+% To use the \texttt{asypictureB} package, 
+% the \texttt{.tex} file should be run with shell-escape 
+% enabled:
+% \begin{Verbatim}[commandchars=\\\{\},gobble=2]
+% pdflatex -shell-escape \meta{filename}
+% \end{Verbatim}  
+% [Note that |latex|, |lualatex|, etc.\ can be substituted for |pdflatex|, although
+% you should make sure that the engine you use is compatible with whatever 
+% graphics formats your Asymptote pictures are compiled to.]
+% 
+% \subsection{Running without shell escape}
+% 
+% If you are unwilling to use shell-escape, \packagename{asypictureB} 
+% creates a script that makes it easy to execute the necessary commands 
+% afterwards. To use it, run the following three commands at the terminal. 
+% For convenience, it is assumed that the name of the \LaTeX\ source file 
+% is |foo.tex|.
+% 
+% \bigskip\noindent
+% \begin{minipage}{0.48\linewidth}
+% Windows:
+% \begin{Verbatim}[commandchars=\\\{\},gobble=2]
+% pdflatex foo
+% foo-asy_compile.bat
+% pdflatex foo
+% \end{Verbatim}
+% \end{minipage}
+% \hfill
+% \begin{minipage}{0.48\linewidth}
+% Mac OS X and Unix-like systems:
+% \begin{Verbatim}[commandchars=\\\{\},gobble=2]
+% pdflatex foo
+% sh foo-asy_compile.sh
+% pdflatex foo
+% \end{Verbatim}
+% \end{minipage}
+% 
+% \medskip\noindent
+% Instead of |pdflatex|, one may use |latex|, |lualatex|, \ldots. Asymptote 
+% errors will be visible as \TeX\ errors on the second run of \LaTeX.
+% 
+% \begin{warning}
+% This method is not entirely foolproof. In particular, if |pdflatex| is run 
+% twice in a row without running the \meta{filename}-|asy_compile| 
+% script in between, then 
+% Asymptote pictures which have been compiled at some point in the past, even 
+% if they have since been altered, will 
+% not be recompiled. Should this happen, you can force every |asypicture| 
+% to be recompiled using the |\RequireAsyRecompile| command.
+% \end{warning}
+% 
+% \paragraph{The safer method}
+% If you want to compile a \TeX\ source file from someone else (e.g., 
+% the internet), you may want neither to enable shell-escape nor to 
+% run a script generated by this file.
+% A safer way to compile 
+% all Asymptote pictures generated by \packagename{asypictureB} 
+% (and for that matter by the \packagename{asymptote} package) is to run 
+% |asy -noV |\meta{filename}|-*.asy| after compiling \meta{filename}|.tex|.
+% Once this is done, all the Asymptote files should be compiled, will be 
+% correctly imported upon a second run of |pdflatex| (or |latex|, \ldots).
+% Re-running |asy| is not necessary until and unless any of the Asymptote 
+% pictures change. This method is ``safe'' in that you have greater 
+% control over which programs are actually being run.
+% 
+% This method will also work for your own files-in-progress, but is not 
+% recommended for two reasons:
+% \begin{itemize}
+% \item Asymptote errors will not be repackaged as \TeX\ errors, negating 
+% one of the main features of the \packagename{asypictureB} package.
+% \item All Asymptote pictures will be recompiled, even if they have not 
+% changed since the last run. This can add considerably to the compile time.
+% \end{itemize}
+% 
+% \subsection{Dependencies}
+% As currently implemented, the \packagename{asypictureB} package requires
+% the packages \packagename{fancyvrb} (tested with version 2.8), 
+% \packagename{graphicx} (tested with version 2005/11/14), 
+% \packagename{pgfkeys}, and \packagename{ifplatform} (tested with 
+% version 0.4). In fact, it depends 
+% on undocumented internals of the \packagename{fancyvrb} package, so 
+% later versions of this package could conceivably break it as well as earlier versions.
+% 
+% If shell-escape is 
+% not enabled, it also requires the \packagename{verbatimcopy} package, 
+% version 0.06 or later.  Since \packagename{verbatimcopy} is not backwards 
+% compatible, earlier versions will, in fact, break \packagename{asypictureB}.
+% 
+% \section{Usage}
+%
+% \DescribeEnv{asypicture} Code for Asymptote pictures should be placed 
+% within the |asypicture| environment, which takes one mandatory argument:
+% a list of comma-separated expressions of the form 
+% \meta{key}\texttt{=}\meta{value}. It is strongly recommended that the 
+% key |name| always be used, since this will prevent the package from 
+% re-compiling pictures whose code has not changed. The time saving can 
+% be substantial if you have a document with a significant number of 
+% Asymptote pictures. 
+% 
+% Keys other than |name| are passed onto an |\includegraphics| 
+% command from the \packagename{graphicx} package. The keys should be given 
+% in the following order:
+% \begin{enumerate}
+% \item Keys other than |scale| or |angle|.
+% \item The |scale| key (if it is used).
+% \item The |angle| key (if it is used).
+% \end{enumerate}
+% The way the package is currently implemented, the |scale| and |angle| keys 
+% will effectively be evaluated last, regardless of the order in which they 
+% are given. However, this behavior is not ideal and may change in future versions 
+% of the package; the goal would be that keys should be evaluated in the order 
+% in which they are given. For the time being, giving keys in the order specified 
+% should ensure compatibility with future versions.
+% 
+% It is possible to expand macros within an |asypicture| environment by using an 
+% at symbol
+% \texttt{@} in place of a backslash |\|. For instance, the line
+% \begin{Verbatim}[gobble=2]
+% size(@the@linewidth, 0);
+% \end{Verbatim}
+% will be translated to something like
+% \begin{Verbatim}[gobble=2]
+% size(345.0pt, 0);
+% \end{Verbatim}
+% before being compiled by Asymptote.
+% 
+% \bigskip\noindent
+% \DescribeEnv{asyheader}Code within an |asyheader| environment is appended to 
+% the ``header,'' which is inserted at the beginning of every \texttt{.asy} file 
+% output by the \packagename{asypictureB} package. Initially, the header 
+% consists of the two lines
+% \begin{Verbatim}[gobble=2]
+% defaultpen(fontsize(@getfontsize pt));
+% settings.prc = false;
+% \end{Verbatim}
+% Again, macros can be expanded inside an |asyheader| environment by prefixing them 
+% by @ rather than |\|. The macros are fully expanded when they are added to the 
+% header, not when they are written to a file. Thus, for instance, in a 10-point 
+% document, the first line of the header will always read 
+% \begin{Verbatim}[gobble=2]
+% defaultpen(fontsize(10pt));
+% \end{Verbatim}
+% even if the font size is later changed to 12 points.
+% 
+% Note that any change to the header will require all subsequent |asypicture| 
+% environments to be recompiled.  In a document with many Asympotote images, 
+% this could take a while.
+% 
+% \bigskip\noindent
+% \DescribeMacro{\getfontsize}The |\getfontsize| macro is an alias for 
+% |\f@size| that does not require |\makeatletter|. It expands to the current 
+% font size (without the suffix |pt|).
+% 
+% \bigskip\noindent\DescribeMacro{\asylistingfile}The |\asylistingfile| macro
+% contains the filename of the Asymptote code for the most recent |asypicture|.
+% It can be used with commands from e.g. \packagename{fancyvrb} or 
+% \packagename{listings} to display the Asymptote code for an image.
+% 
+% \bigskip\noindent
+% \DescribeMacro{\RequireAsyRecompile}\DescribeMacro{\AsyCompileIfNecessary}
+% By default, Asymptote images are compiled only if the Asymptote code has changed. 
+% The command |\RequireAsyRecompile| changes this setting to make all subsequent 
+% images recompile even if the code has not changed. 
+% (This can be useful, for instance, 
+% if you have just updated Asymptote.) The command 
+% |\AsyCompileIfNecessary| restores the default behavior for all subsequent 
+% Asymptote pictures.
+% 
+% \subsection{Keys for \texttt{asypicture}}
+% 
+% \DescribeMacro{name} If the key-value combination |name=|\meta{picturename} 
+% appears in the mandatory argument to an |asypicture| environment, then the 
+% contents of that environment will be saved to the file 
+% \begin{Verbatim}[gobble=2,commandchars=\\\{\}]
+% \meta{filename}-\meta{picturename}.asy
+% \end{Verbatim}
+% where \meta{filename} is the name of the current |.tex| file (not including 
+% the |.tex| extension). 
+% The compiled Asymptote picture is saved to an image file such as 
+% \texttt{\meta{filename}-\meta{picturename}.eps},
+% \texttt{\meta{filename}-\meta{picturename}.pdf}, or
+% \texttt{\meta{filename}-\meta{picturename}.png}.
+% 
+% Alphanumeric characters are allowed in the |name| key, as are the 
+% characters |-| (hyphen) and |_| (underscore). Other characters (including 
+% spaces, asterisks, etc.) should 
+% be avoided. The key may begin with any allowed character; however, names 
+% consisting of a single number with three or fewer digits are discouraged, 
+% since these may conflict with the \packagename{asymptote} package.
+% 
+% Although the |name| key is technically not required, 
+% it is strongly recommended that distinct names be given 
+% to all the different |asypicture| 
+% environments. This allows the \packagename{asypictureB} package to avoid 
+% recompiling pictures whose code has not changed---even if the pictures are
+% reordered.  
+% 
+% If the name \meta{picturename} has been used before, 
+% a suffix will be appended to it: |__1| for the first repeat, |__2| for 
+% the second repeat, etc. Thus, if the same name (say |foo|) 
+% is used for several |asypicture|s, 
+% then deleting the first of these will force all the others to recompile; 
+% but changing a picture of a different name will not affect any of the 
+% pictures named |foo|.
+% 
+% If no |name| key is given, the key-value combination |name=noname| is 
+% assumed. This default can be changed using the |\asyset| command: after 
+% the line 
+% \begin{Verbatim}[gobble=2]
+% \asyset{name = foo}
+% \end{Verbatim}
+% nameless pictures will be called |foo| rather than |noname|.
+% 
+% \begin{warning}
+% If \packagename{asypictureB} determines that the contents of an |asypicture|
+% environment named \meta{picturname} 
+% have changed since the last run, it will delete 
+% all of the following files that exist:
+% \begin{Verbatim}[gobble=2,commandchars=\\\{\}]
+% \texttt{\meta{filename}-\meta{picturename}.eps}
+% \texttt{\meta{filename}-\meta{picturename}.pdf}
+% \texttt{\meta{filename}-\meta{picturename}.png}
+% \end{Verbatim}
+% \end{warning}
+% 
+% \subsection{Styles}
+% \DescribeMacro{\asyset} 
+% Since \packagename{asypictureB} uses \packagename{pgfkeys} for keys, 
+% it is possible to create new keys, called ``styles,'' that set 
+% several other keys at once. For instance, the following line 
+% \begin{Verbatim}[gobble=2]
+% \asyset{mysize/.style = {width=6cm, height=4cm}}
+% \end{Verbatim}
+% creates a new key called |mysize|. Any time in the document after this 
+% line, the command
+% \begin{Verbatim}[gobble=2]
+% \begin{asypicture}{name=picturename, mysize}
+% \end{Verbatim}
+% is exactly equivalent to the line
+% \begin{Verbatim}[gobble=2]
+% \begin{asypicture}{name=picturename, width=6cm, height=4cm}
+% \end{Verbatim}
+% This is precisely the same style mechanism that is used in TikZ; in 
+% fact, |\asyset|\marg{keys} is equivalent to |\pgfkeys{/asy/.cd,|\meta{keys}|}|, 
+% much as |\tikzset|\marg{keys} is equivalent to |\pgfkeys{/tikz/.cd,|\meta{keys}|}|.
+% 
+% The |\asyset| command may be used in the preamble or anywhere in the body of 
+% the document where macros are processed normally. It may not be used in the 
+% body of an |asypicture| or any other verbatim-like environment.
+% 
+% \section{Examples}
+% 
+% Here is a simple example:
+% 
+% \noindent\def\asywidth{2.5cm}
+% \begin{minipage}[t]{\asywidth}
+% \vspace*{0pt}
+% \begin{asypicture}[gobble=2]{name = sphere_image, width=\asywidth}
+% settings.outformat = "png";
+% settings.render = 16;
+% size(@asywidth,0);
+% import three;
+% draw(unitsphere);
+% \end{asypicture}
+% \end{minipage}
+% \hfill
+% \begin{minipage}[t]{\dimexpr\linewidth-\asywidth-10pt\relax}
+% \vspace*{0pt}
+% \begin{Verbatim}[gobble=2,codes={\catcode`@=0},frame=single]
+% \begin{asypicture}{name=sphere_image}
+% settings.outformat = "png";
+% settings.render = 16;
+% size(@asywidth,0);
+% import three;
+% draw(unitsphere);
+% \end{asypicture}
+% \end{Verbatim}
+% \end{minipage}
+% 
+% \medskip\noindent
+% Here is an example that uses the user-defined macro |\asywidth| 
+% inside the Asymptote code to avoid duplicate code.
+% 
+% \begin{Verbatim}[gobble=2,tabsize=4,frame=single]
+% \noindent\def\asywidth{4cm}
+% \begin{asypicture}{name=triangle,width=\asywidth}
+% 	settings.outformat="pdf";
+% 	size(@asywidth,0);
+% 	draw((0,0) -- (1,0) -- (1,1) -- cycle);
+% 	dot((1,0), L=Label(
+% 		"\textbf{Bold} \textsc{Smallcaps}",
+% 		align=NE));
+% \end{asypicture}
+% \hfill
+% \begin{minipage}{\dimexpr\linewidth-\asywidth-15pt\relax}
+% \VerbatimInput[frame=leftline]{\asylistingfile}
+% \end{minipage}
+% \end{Verbatim}

+% \section{Error handling}
+% 
+% It has been stated several places in this document that 
+% \packagename{asypictureB} repackages Asymptote errors as 
+% \TeX\ errors (and at least once that this feature, among others, 
+% could stand significant improvements). In this section is described 
+% exactly how these errors are repackaged, at least as of the current 
+% implementation. None of this is guaranteed to remain the same in 
+% future versions.
+% 
+% When \packagename{asypictureB} tells Asymptote to compile the file 
+% \begin{quote}
+% \texttt{\meta{filename}-\meta{picturename}.asy},
+% \end{quote}
+%  it reroutes all 
+% warning and error messages to the file 
+% \begin{quote}
+% \texttt{\meta{filename}-\meta{picturename}\_errors.txt}.
+% \end{quote}
+% Once the Asymptote run is complete, it checks whether the error file 
+% has any content. If so, it throws a \LaTeX\ package error and displays 
+% the contents of the error file, which include all the errors and 
+% warnings issued by Asymptote. One unfortunate 
+% consequence of this procedure is that 
+% a warning by Asymptote will be translated into a full-fledged error, 
+% which is why the \LaTeX\ error message begins with the words 
+% ``Possible Asymptote error."
+% 
+% The \LaTeX\ error message will give the line number of the 
+% |\end{asypicture}| command for the |asypicture| that caused the error, which 
+% is of limited use in isolating the error.
+% More precise line numbers are given by the Asymptote error log; 
+% however, these line numbers are 
+% for the |asy| file rather than the |tex| file, and consequently not 
+% terribly helpful.
+% 
+% To allow the user to locate the line on which the actual error occurred, 
+% the \packagename{asypictureB} package attempts to parse the Asymptote 
+% error log and print out the five lines leading up to the error.  More precisely, 
+% it does the following:
+% \begin{enumerate}
+% \item If the first line of the error log is of the form
+% \begin{quote}
+% \texttt{\meta{filename}-\meta{picturename}.asy:\meta{number}.\meta{stuff}}
+% \end{quote}
+% then the \meta{number} is extracted. If the first line is not of this 
+% form, then the parsing is considered to have failed. As a consequence, 
+% if the first line of the error log is a warning but an error shows up 
+% later, \packagename{asypictureB} will not notice the error message.
+% In the author's experience, this problem does occur, but not often.
+% \item Assuming \meta{number} was extracted successfully, the lines 
+% of the |asy| file from 
+% the inclusive range $\meta{number}-5$ to \meta{number} are displayed
+% as part of the \LaTeX\ error message. These lines are usually identical 
+% and almost always similar to the lines in the actual |tex| file 
+% leading up to the error. In the author's experience, this is usually enough 
+% information to locate without difficulty the line on which the error 
+% occurred.\footnote{I.e., the line that caused Asymptote to choke. 
+% The usual rules of debugging apply: the line on which the compiler identified 
+% an error might have been correct if not for an earlier mistake that 
+% was syntactically correct.}
+% \end{enumerate}
+% 
+% \noindent Here's an example: Consider \LaTeX\ file
+% \begin{Verbatim}[gobble=2,numbers=left,tabsize=4]
+% \documentclass{article}
+% \usepackage{asypictureB}
+%  \begin{document}
+% \def\asywidth{5cm}
+% \begin{asypicture}{name=error_example}
+% 	// A comment
+% 	size(@asywidth, 0);
+% 	path l1 = (0,0) -- (1,1);
+% 	// Another comment
+% 	draw(box((0,0),(1,1)))
+% 	draw(l1, dotted);
+% 	draw(l2, dashed);
+% \end{asypicture}
+% \end{document}
+% \end{Verbatim}
+% If this file is saved as \texttt{asyerrorexample.tex} and then 
+% compiled with the shell-escape option, the following error results:
+% \begin{Verbatim}[gobble=2]
+% ./asyerrorexample.tex:13: Package asypicture Error: 
+% Possible Asymptote error:
+% asyerrorexample-error_example.asy: 10.5: syntax error 
+% error: could not load module 'asyerrorexample-error_example.asy'
+% 
+% 
+% 
+% 6     size(5cm, 0);
+% 7     path l1 = (0,0) -- (1,1);
+% 8     // Another comment
+% 9     draw(box((0,0),(1,1)))
+% 10     draw(l1, dotted);
+% .
+% 
+% See the asypicture package documentation for explanation.
+% Type  H <return>  for immediate help.
+%  ...                                              
+%                                                    
+% l.13 \end{asypicture}
+% \end{Verbatim}
+% The first two lines of the \LaTeX\ error message identifies that the 
+% |asypicture| environment ending on line 13 may have produced an error.
+% The next two lines are the Asymptote error log: they explain that this 
+% was, in fact, a syntax error. Looking at the five lines displayed, 
+% one can determine that the difficulty was a comma omitted 
+% on line 9 of the Asympote file. (It is diagnosed on line 10 because 
+% of how the compiler works.) Looking at the context, this corresponds 
+% to line 10 of the \LaTeX\ file.
+% 
+% Note that the macro |@asywidth| in the |asypicture| code 
+% has been expanded to \texttt{5cm} in the error message.
+% 
+% \section{Macros in \texttt{asypicture}s}
+% 
+% When the author first conceived of allowing macros in an 
+% |asypicture| environment, the goal was to allow expressions like 
+% |size(@asywidth,0);| where |\asywidth| was a user-defined macro 
+% also used in the \LaTeX\ code to avoid hard-coding numbers. 
+% However, it was almost immediately apparent that this feature 
+% has more sophistocated uses, such as allowing user-defined 
+% syntax or even creating something similar to templates. 
+% 
+% \subsection{Limitations}
+% 
+% Before discussing the nifty features, let's discuss the fairly 
+% severe limitations they will have to work around.
+% 
+% \begin{description}
+% \item[No grouping symbols.] If a macro takes a mandatory argument 
+% inside braces |{}|, then that macro cannot be used inside an 
+% |asypicture|.
+% \item[Purely expandable macros only.] Macros will be expanded, but not 
+% executed. In particular, macros that allow optional arguments will usually 
+% go horribly wrong.
+% \item[One line only.] As we will discuss, it is 
+% possible to use ``unconventionally delimited'' arguments. However, even 
+% in this case, a macro and all its arguments must fit on a single line.
+% \end{description}
+% 
+% Since the first two points all but forbid the use of macros with 
+% conventional arguments, it might 
+% be wondered whether macros in Asymptote code can be used for anything 
+% more interesting than storing user-defined lengths. They can.
+% 
+% \subsection{Single-token arguments}
+% 
+% [This is really more a fix than an example, but this seems as good a 
+% place as any to discuss it.]
+% 
+% Some macros, such as |\the|,
+% take arguments that consist only of a single character or 
+% control sequence. For instance, |\the\textwidth| expands to something like 
+% \texttt{345.0pt}, whereas |\textwidth| by itself expands only to 
+% |\textwidth|. This can be significant if you want to produce an 
+% Asymptote picture that takes up a specified fraction of the text width.
+% 
+% \subsection{Unconventionally delimited arguments}
+% 
+% The \TeX\ primitive |\def| can be used to produce macros that are 
+% quite flexible about how they are delimited. For instance, the \TeX\ code
+% \begin{Verbatim}[gobble=2]
+% \def\draw#1;{draw(#1);}
+% \end{Verbatim}
+% will take as its argument everything between the |\draw| command and the 
+% first subsequent semicolon. If this line showed up in \TeX\ code 
+% (preferably in the preamble), then subsequent |\asypicture| environments 
+% could include a line such as 
+% \begin{Verbatim}[gobble=2]
+% @draw box((0,0), (1,1));
+% \end{Verbatim}
+% as an arguably more aesthetic alternative to the translation
+% \begin{Verbatim}[gobble=2]
+% draw( box((0,0), (1,1)));
+% \end{Verbatim}
+% 
+% A more advanced example is essentially a template for a sorting 
+% function\footnote{The algorithm here is a somewhat inefficient 
+% mergesort.}. 
+% Include the following code in the \TeX\ preamble:
+% \begin{Verbatim}[gobble=2]
+% \def\definesortfunction #1;{%
+% #1[] sort(#1[]  a) {
+%     if (a.length <= 1) return a; 
+%     static #1[] merge(#1[] b, #1[] c) { 
+%         #1[] toreturn;
+%         int i = 0, j = 0;
+%         while (i < b.length && j < c.length) {
+%             if (!(c[j] < b[i])) { toreturn.push(b[i]); ++i; }
+%             else { toreturn.push(c[j]); ++j; }
+%         }
+%         while (i < b.length) {
+%             toreturn.push(b[i]);
+%             ++i;
+%         }
+%         while (j < c.length) {
+%             toreturn.push(c[j]);
+%             ++j;
+%         }
+%         return toreturn;
+%     }
+%     int halfway = floor(a.length / 2);
+%     #1[] b = sort(a[0:halfway]);
+%     #1[] c = sort(a[halfway:a.length]);
+% 
+% 
+%     return merge(b, c);
+% }}
+% \end{Verbatim}
+% Then within any |asypicture| environment, the line |@definesortfunction T;| 
+% can be used to define a function |T[] sort(T[])| that returns a sorted 
+% version of its argument, for any type |T| for which the less than operator 
+% |<| is defined. For instance, within an |asypicture|, the code 
+% \begin{Verbatim}[gobble=2]
+% bool operator <(pair a, pair b) {
+%    return (a.x < b.x  || (a.x == b.x && a.y < b.y));
+% }
+%
+% @definesortfunction pair;
+% \end{Verbatim}
+% makes available a lexicographic sorting routine for ordered pairs of real 
+% numbers.
+% 
+% Unfortunately, while this compiles correctly, the resulting Asymptote 
+% file has no line breaks in the entire definition of the sort function.
+% If you want the Asymptote code (as opposed to just the |asypicture| code) 
+% to be readable, the following setup, proposed by Enrico Gregorio\footnote{
+% \url{http://tex.stackexchange.com/a/160740/484}}, does the job:
+% 
+% \begin{Verbatim}[gobble=2]
+% \begingroup
+% \endlinechar=`^^J \obeyspaces% end of lines are newlines
+% \gdef\definesortfunction #1;{% eat up the space following the macro
+% #1[] sort(#1[]  a) {
+%     if (a.length <= 1) return a; 
+%     static #1[] merge(#1[] b, #1[] c) { 
+%         #1[] toreturn;
+%         int i = 0, j = 0;
+%         while (i < b.length && j < c.length) {
+%             if (!(c[j] < b[i])) { toreturn.push(b[i]); ++i; }
+%             else { toreturn.push(c[j]); ++j; }
+%         }
+%         while (i < b.length) {
+%             toreturn.push(b[i]);
+%             ++i;
+%         }
+%         while (j < c.length) {
+%             toreturn.push(c[j]);
+%             ++j;
+%         }
+%         return toreturn;
+%     }
+%     int halfway = floor(a.length / 2);
+%     #1[] b = sort(a[0:halfway]);
+%     #1[] c = sort(a[halfway:a.length]);
+% 
+% 
+%     return merge(b, c);
+% }% this % is necessary
+% }% this % is necessary
+% \endgroup% this % is necessary
+% \end{Verbatim}
+% 
+% \begin{warning}
+% If two commands use the same unconventional delimiter, then they cannot 
+% be nested. In particular, a command cannot appear inside its own argument. 
+% This is one of the reasons people usually delimit with grouping 
+% symbols, which is not an option here, short of using |@bgroup| and 
+% |@egroup| with copious occurrences of |@expandafter|.
+% \end{warning}
+% \begin{warning}
+% The |\def| command is not expandable. Thus, the code defining the 
+% macros must be given \emph{outside} |asypicture| environments, 
+% even when the macros are intended for use exclusively inside |asypicture|s.
+% \end{warning}
+% 
+% 
+% \section{Missing features} 
+% 
+% The introduction of this documentation touted ways in which 
+% \packagename{asypictureB} improves on the behavior of the \packagename{asymptote}
+% package. In this section, I clarify ways in which it falls short and 
+% describe how to compensate where possible. My hope 
+% is that these differences would narrow in both directions until only 
+% one package is necessary---preferably the official \packagename{asymptote} 
+% package.
+% 
+% Note that some of these ``missing features'' cannot be fixed without 
+% breaking backwards compatibility. This is largely why the package is 
+% named \packagename{asypictureB}, allowing room for a future, more 
+% powerful version named \packagename{asypicture}, in case the 
+% \packagename{asymptote} package does not step into the gap.
+% 
+% \begin{framed}
+% \noindent\textbf{Tip:} To retrieve the documentation for the 
+% \packagename{asymptote} \LaTeX\ package, 
+% type \texttt{texdoc asy-latex} at the command line. To retrieve the 
+% documentation for the Asymptote programming language, type 
+% \texttt{texdoc asymptote}. To retrieve the documentation for 
+% \packagename{asypictureB}, type \texttt{texdoc asypictureB}.
+% \end{framed}
+% 
+% \paragraph{No 3d interaction}
+% One of the most spectacular features of the \packagename{asymptote} package is 
+% the embedding of interactive three-dimensional images in PDF files. 
+% (Note that this requires the |inline| option when loading the package.)
+% The \packagename{asypictureB} package currently has no such feature. 
+% In fact, the default header includes 
+% the line \texttt{settings.prc = false;} to prevent Asymptote from trying 
+% to produce an interactive (|prc|) image, since this might break things.
+% 
+% \paragraph{No \texttt{inline} option}
+% A second feature that is important, but less spectacular, is the |inline| 
+% option itself, which causes the Asymptote labels to be compiled (in \LaTeX) 
+% with all the 
+% same packages loaded and macros defined as in the original document. 
+% For instance, font consistency between the Asymptote images and the 
+% larger document is ensured by this option.
+% It comes with an important limitations---Asymptote cannot use size information 
+% about the labels when this option is in use.
+% 
+% The closest 
+% equivalent in the \packagename{asypictureB} package is the immediate 
+% expansion of macros introduced by the @ symbol. This does not have the 
+% drawback of the |inline| option, and has many additional uses. However, 
+% it is less flexible inside labels (since, e.g., macros with arguments 
+% cannot be used this way), and does not ensure font consistency. 
+% 
+% To compensate for this when using \packagename{asypictureB}, important 
+% packages and macro definitions should be echoed in the Asymptote header. 
+% Here is an example of code that could be placed in the preamble of a document 
+% to make the macro |\RR| (for $\mathbb R$) available in both the document 
+% text and the labels of its Asymptote pictures:
+% \begin{Verbatim}[gobble=2]
+% \usepackage{amssymb}
+% \newcommand{\RR}{\mathbb{R}}
+% \begin{asyheader}
+% usepackage("amssymb");
+% texpreamble("\newcommand{\RR}{\mathbb{R}}");
+% \end{asyheader}
+% \end{Verbatim}
+% 
+% \paragraph{The output format is not automatically set.} 
+% When using \packagename{asymptote}, the output format is automatically 
+% set to either |eps| or |pdf| depending on what \TeX\ engine is being run 
+% (and which kind of graphics file it prefers). When using \packagename{asypictureB}, 
+% no such provision is made; if any format other than |eps| is desired, 
+% it must be selected by including the Asymptote code 
+% \texttt{settings.outformat="pdf";} (or |"png"|). This is by design, to allow 
+% the use of |png| files; but it can be a bit annoying at times. To set all 
+% Asymptote files to have |pdf| format, include the code 
+% \begin{Verbatim}[gobble=2]
+% \begin{asyheader}
+% settings.outformat="pdf";
+% \end{asyheader}
+% \end{Verbatim}
+% in the preamble (or anywhere prior to the first |asypicture| environment).
+% 
+% \paragraph{Keys to \texttt{asypicture} are not conveyed to Asymptote}
+% In the \packagename{asymptote} package, keys like |width| and 
+% |height| are conveyed both to the implicit |\includegraphics| command 
+% and to Asymptote. In \packagename{asypictureB}, they are conveyed only 
+% to the |\includegraphics| command; font size and even resolution (for 
+% rasterized images) will be 
+% changed in the process of scaling the picture. 
+% Thus, the preferred method is to set the width, height, etc.\ 
+% through Asymptote's |size| command.

+% Note that in the ``good'' example, the key |width=3.5cm| is necessary 
+% only if you want to make sure the included image has \emph{precisely} 
+% the specified 
+% width, and probably not even then.
+% 
+% \paragraph{No spaces in file names} The \packagename{asymptote} package
+% takes measures to accomodate peculiar file names---in particular, file 
+% names that include spaces. The \packagename{asypictureB} package does not.
