+The `getitems' package v1.0
+Copyright (C) 2016 Anders Hendrickson (anders.hendrickson@snc.edu)
+
+This package provides a \gatheritems command to parse a list of data separated 
+by \item tokens.  This makes it easier to define custom environments which 
+structure their data in the same way that itemize or enumerate do.

+% \maketitle
+%
+% \section{Overview}
+%
+% The |enumerate| and |itemize| environments of \LaTeX\ organize their contents
+% through the use of the |\item| command.  Each entry in these lists is prefaced
+% with the command |\item|, making for very compact and easily readable source 
+% code.  Package designers may find it useful to use the same syntax for
+% their custom environments.  The \textsf{getitems} package makes
+% it easy to code such environments by parsing a string of tokens, separating them
+% by the occurrence of |\item|'s, and saving the contents as macros.  
+% Nested environments are handled correctly.
+% 
+% Moreover, some typesetting tasks naturally consist of a ``header'' followed by 
+% several related items; one example would be a multiple-choice question on a 
+% school examination.  This package saves any \TeX\ tokens appearing before the
+% first |\item| as the zeroth item for special handling.
+% 
+% \section{Usage}
+% 
+% \DescribeMacro{\gatheritems}
+% To parse a string of text, such as the body of an environment,
+% call 
+% \begin{center}
+%   |\gatheritems|\marg{text to parse}.
+% \end{center}
+% This will scan through the \meta{text to parse}, dividing it at each |\item|
+% while respecting \TeX\ groupings and nested environments, 
+% and store the divided portions of text into memory.
+% 
+% \DescribeMacro{numgathereditems}
+% The total number of items in the parsed text is stored in the \LaTeX\ counter
+% |numgathereditems|.
+% 
+% \DescribeMacro{\gathereditem}
+% To retrieve a stored item, you may call |\gathereditem|\marg{item number};
+% the \meta{item number} should expand to an arabic representation of a nonnegative integer.
+% Any tokens occurring before the first |\item| may be retrieved with
+% |\gathereditem{0}|.
+% 
+% \DescribeMacro{\loopthroughitemswithcommand}
+% Once the items are gathered, it will probably be necessary to loop through
+% all of them.  
+% Of course a package author can do so manually, but |getitems| provides a 
+% built-in way to do so by calling |\loopthroughitemswithcommand|\marg{macro}.
+% The \meta{macro} must be a control sequence taking exactly one argument;
+% it will be called successively with the item text.
+% For example,
+% \begin{quote}
+% \begin{tabular}{p{3in}p{1.5in}}
+% \begin{minipage}{3in}
+%   \begin{Verbatim}[gobble=6]
+%     \gatheritems{%
+%       Zero
+%       \item One
+%       \item Two
+%       \item Three
+%     }
+%     \loopthroughitemswithcommand{\fbox}
+%   \end{Verbatim}
+% \end{minipage}
+% &
+% \begin{minipage}{1.5in}
+%     \gatheritems{%
+%       Zero
+%       \item One
+%       \item Two
+%       \item Three
+%     }
+%     \loopthroughitemswithcommand{\fbox}
+% \end{minipage} 
+% \end{tabular}
+% \end{quote}
+% The result is the same as processing |\fbox{One}|, then |\fbox{Two}|, and finally |\fbox{Three}|.
+% Note that |\loopthroughitemswithcommand| deliberately ignores the zeroth entry, which occurs
+% before the first |\item|.
+% 
+% \DescribeMacro{currentitemnumber}
+% Typically the package author will create a custom macro to process each item.
+% This macro may make use of the index of the loop, which is stored in the 
+% \LaTeX\ counter |currentitemnumber|.
+% \DescribeMacro{\ifgatherbeginningofloop}
+% A conditional |\ifgatherbeginningofloop| is also available,
+% which only evaluates as true when
+% processing the first item; it is thus functionally equivalent to
+% |\ifnum1=\c@currentitemnumber|.
+% The custom macro may take advantage of this to run special code for the first item only.
+% 
+% 
+% \section{Example}
+% An example using |getitems| to create a custom environment may be informative.
+% We use the |\NewEnviron| command from the |environ| package 
+% (automatically loaded by |getitems|) to define a |question| environment;
+% the body between the |\begin{question}| and |\end{question}| is available as |\BODY|.
+% \medskip

+% \begin{tabular}{p{3in}p{1.5in}}

+% \section{Implementation}
+% 
+% We need the |trimspaces| package to remove excess spaces
+% from the items we find.
+% Although the |environ| package is not used by |getitems| itself,
+% it will almost certainly be needed.
+%    \begin{macrocode}
+\RequirePackage{environ}
+\RequirePackage{trimspaces}
+\let\xa=\expandafter
+%    \end{macrocode}
+%  \begin{macro}{\gathereditem}
+%    The $k$th item found will be stored in the macro |\getitems@item@|\meta{k};
+%    the user can access it through the |\gathereditem| macro.
+%    \begin{macrocode}
+\def\gathereditem#1{\csname getitems@item@#1\endcsname}
+%    \end{macrocode}
+%  \end{macro}
+%  
+%  \begin{macro}{numgathereditems}
+%    We define the \LaTeX\ counter |numgathereditems|.
+%    \begin{macrocode}
+\newcounter{numgathereditems}
+%    \end{macrocode}
+%  \end{macro}
+%  
+%  \begin{macro}{\gatheritems}
+%    The main control sequence of this package is |\gatheritems|.
+%    The na\"ive strategy is to use the delimiter mechanism of \TeX\ to
+%    split the text at the first occurrence of the token ``|\item|.''
+%    We add |\getitems@relax| before, 
+%    and ``|\item\getitems@terminalitem|'' after, the text to help us
+%    detect empty items and prevent
+%    errors after we have found all the genuine |\item|'s.
+%    \begin{macrocode}
+\long\def\gatheritems#1{%
+  \setcounter{getitems@begindepth}{0}%
+  \setcounter{numgathereditems}{0}%
+  \xa\long\xa\gdef\csname getitems@item@0\endcsname{}%
+  \gatheritems@int\getitems@relax#1\item\getitems@terminalitem\getitems@endgatheritems
+  \xa\let\xa\gatheredheader\xa=\csname getitems@item@0\endcsname
+}
+%    \end{macrocode}
+%  \end{macro}
+%  The trouble with the na\"ive strategy is that it won't handle nested
+%  environments correctly.  To do that, we need to keep track of how deeply
+%  nested we are with the macro |\getitems@trackbegindepth|, defined below.
+%  That macro stores its results in the \LaTeX\ counter |getitems@begindepth|;
+%  a value of 0 indicates the top-level within the argument of |\gatheritems|.
+%    \begin{macrocode}
+\def\@getitems@terminalitem{\getitems@terminalitem}%
+\def\@dummy@relax{\getitems@relax}%
+\long\def\gatheritems@int#1\item#2\getitems@endgatheritems{%
+  \getitems@trackbegindepth{#1}%
+  \ifnum\c@getitems@begindepth=0\relax
+%    \end{macrocode}
+% At this point we have gathered a complete |\item|; we have not stopped 
+% accidentally at a sub|\item|.  The original |\item| might have had no content,
+% in which case |#1| will be simply ``|\getitems@relax|'', and we do nothing;
+% otherwise we strip off the |\getitems@relax| and store those tokens in 
+% |\getitems@item@|\meta{numgathereditems}.
+%    \begin{macrocode}
+    \def\getitems@test@i{#1}%
+    \ifx\getitems@test@i\@dummy@relax
+      \relax
+    \else
+      \xa\xa\xa\g@addto@macro
+         \xa\xa\csname getitems@item@\the\c@numgathereditems\endcsname
+            \xa{\getitems@stripfirsttokenfrom#1\getitems@endstrip}%
+    \fi
+%    \end{macrocode}
+% Now we test whether we have reached the end of the text to be parsed.
+% This is the case if |#2| is simply |\getitems@terminalitem|,
+% and we stop the recursion.
+% Otherwise there is at least one more |\item| to process, so we increment |numgathereditems|,
+% prepare |\getitems@item@|\meta{k+1},
+% and prepare to recurse.
+%    \begin{macrocode}
+    \def\getitems@test@ii{#2}%
+    \ifx\getitems@test@ii\@getitems@terminalitem
+      \let\getitems@next=\relax
+    \else
+      \stepcounter{numgathereditems}%
+      \xa\gdef\csname getitems@item@\the\c@numgathereditems\endcsname{}%
+      \def\getitems@next{\gatheritems@int\getitems@relax#2\getitems@endgatheritems}%
+    \fi
+  \else
+%    \end{macrocode}
+% We are now in the case where |getitems@begindepth|${}\neq 0$.
+% This essentially means that the text in |#1| has more |\begin|'s than |\end|'s,
+% so we have not read a complete |\item|; we stopped at an ``|\item|'' token
+% within a sub-environment.
+% We save the text gathered so far to |\getitems@item@|\meta{k},
+% including the |\item| we parsed by mistake,
+% and then call |\gatheritems@int| again to sweep up more tokens.
+%    \begin{macrocode}
+    \xa\xa\xa\g@addto@macro
+       \xa\xa\csname getitems@item@\the\c@numgathereditems\endcsname
+          \xa{\getitems@stripfirsttokenfrom#1\getitems@endstrip}%
+    \xa\g@addto@macro\csname getitems@item@\the\c@numgathereditems\endcsname{\item}%
+    \def\getitems@next{\gatheritems@int\getitems@relax#2\getitems@endgatheritems}%
+  \fi
+  \getitems@next
+}
+%    \end{macrocode}
+% This next macro is used by |\gatheritems@int| to strip off a 
+% dummy |\getitems@relax| token from the beginning of its first parameter.
+%    \begin{macrocode}
+\long\def\getitems@stripfirsttokenfrom#1#2\getitems@endstrip{#2}
+%    \end{macrocode}
+% Here is the code used to track the depth of nesting of |\begin|'s in a text.
+%    \begin{macrocode}
+\newcounter{getitems@begindepth}
+\long\def\getitems@trackbegindepth#1{%
+  \getitems@trackbegindepth@int#1\getitems@terminalbegindepth\getitems@endtrackbegindepth

+\def\@getitems@end{\end}%

+  \else

+  \fi
+  \getitems@trackbegindepth@next
+}
+%    \end{macrocode}
+% \begin{macro}{\loopthroughitemswithcommand}
+%   Finally, we define the user-level command to loop through
+%   the gathered items from 1 through |numgathereditems|.
+%    \begin{macrocode}
