 % If our document contains randomly generated counters, but we wish to typeset
 % the document again without changing those values, then we need a way to save
-% those values. The \textsf{counterz} package offers the following solution: a
-% file \textsf{\meta{jobname}.counters.tex} may be created during the
-% typesetting process to store the necessary information. For example, if the
-% document is named \textsf{Yellowdog.tex}, then the previously generated

-% \textsf{Yellowdog.counters.tex}.

+% them. The command \cs{opencountersfile} creates and opens the write stream to
+% the file \textsf{\meta{jobname}.counters.tex} to store the necessary
+% information. For example, if the document is
+% named \textsf{Yellowdog.tex}, then the previously generated counters and their
+% assigned values will be stored the file \textsf{Yellowdog.counters.tex}. 
+% The author only has to include this command once, prior to any commands used
+% to save the counter values. Additional instances of \cs{opencountersfile} will
+% report an error, as will trying to use the command when the document is set to
+% not randomize (e.g. \cs{norandomizectr}). These error reports are designed to
+% prevent the accidental overwriting of \textsf{\meta{jobname}.counters.tex}.
+%
+% After opening the write stream to \textsf{\meta{jobname}.counters.tex}, the
+% command \cs{savecounter}\marg{counter} may be used to ``save'' the value of
+%\DescribeMacro{\savecounter}
+% \textit{counter} by writing to the file the relevant \cs{providecounter} and

-% written to the file explicitly include the necessary counter prefixes, and

+% \cs{savecounter}. When using \cs{xsavecounter}, the commands that are written
+% to the file include the necessary counter prefixes. Consequently, an author
+% can, if necessary or desired, manually search the file for the value assigned
+% to any randomly generated counter.
+%
+% Once we have generated a file for storing counters, we need a way to recover
+% those values during a subsequent typesetting. The command
+%\DescribeMacro{\inputcountersfile}
+% \cs{inputcountersfile} will input the necessary file, if it exists, and report
+% an error if it does not. Keep in mind that inputting the file will override
+% any previous assignments of those counters, so it is probably best to invoke
+% this command near the beginning of a document. For example, after including an

+%\DescribeMacro{\promptrandomizectr}
+% The command \cs{promptrandomizectr}\oarg{macro}\marg{message}\marg{string}
+% offers an alternative to manually switching between the commands
+% \cs{randomizectr} and \cs{norandomizectr} for different typesettings. The
+% contents of \meta{message} are displayed in the terminal, awaiting a response
+% from the user at the prompt \meta{macro}. If the optional argument is not used
+% then the default prompt is \cs{@typein}. If the optional argument is given, it
+% must be a macro name that includes the backslash. The user's response is
+% stored as a string in \meta{macro} and compared to \meta{string}. If they are
+% equal, then the command \cs{randomizectr} is executed. If they are not equal
+% then \cs{norandomizectr} is executed. 
+%
+% Consider the following example code:
+%
+%\begin{verbatim}
+%\promptrandomizectr[\EnterResponse]{%
+%   ^^J Enter 1 to randomize.
+%   ^^J Enter 2 to not randomize.
+%}{%
+%   1%
+%}%
+%\ifrandomizectr{%
+%   \opencountersfile
+%}{%
+%   \inputcountersfile
+%}%
+%\end{verbatim}
+%
+% \noindent
+% which displays the following in the terminal:
+%
+%\begin{verbatim}
+% Enter 1 to randomize.
+% Enter 2 to not randomize.
+%
+%\EnterResponse=
+%\end{verbatim}
+%
+% \noindent
+% Notice that the first (optional) argument \cs{EnterResponse} begins with a
+% backslash and is displayed with an equals sign ``='' at the prompt. Also note
+% that the second argument contains two instances of the text \texttt{\^{}\^{}J}
+% which is used to produce a line break in the terminal output. Next, note that
+% the third argument \texttt{1} is immediately followed by a percent symbol
+% \texttt{\%} to prevent extra space being included in the string. (If the
+% \texttt{1} was immediately followed by a closing brace instead of a line break
+% in the code, the percent symbol would not be used.) Finally, note that if the
+% user types a \texttt{1} in the terminal and presses Enter, then the commands
+% \cs{randomizectr} and \cs{opencountersfile} will be executed. If the user
+% enters \textit{any other text} or simply presses Enter with no text, then the
+% commands \cs{norandomizectr} and \cs{inputcountersfile} will be executed,
+% despite the instructions to enter a \texttt{2} to achieve this outcome.
