+\begin{abstract}  Provides commands to give consistent, easy-to-remember, easy to edit way to control the size  and blackness
+ of delimiters: append 1-4 ``b''s to command for larger sizes; prepend ``B'' for boldface. These commands reduce the likelihood 
+ of incomplete delimeter pairs and typically use fewer characters than the \LaTeX\ default.

+\section{Installation and the basic delimiters}
+Put \texttt{delimseasy.sty} in a convenient folder and
+add
+\texttt{$\backslash$usepackage\{delimseasy\}}
+ to your  preamble. If  \LaTeX \ can't find the \texttt{sty} file,
+ move it to the folder of your \texttt{tex} file 
+or add a \texttt{PATH} to the \texttt{$\backslash$usepackage} parameter, so you have (for example)
+\newline
+\texttt{$\backslash$usepackage\{C:/user/YOU/Documents/WHEREYOUPUTIT/delimseasy\}}.
+
+\medskip
+Here are the basic macros:
+\begin{equation*}
+\begin{matrix}
+\text{the macro}&	\quad\text{ typesets like }&\quad \text{common name}\\
+\backslash\texttt{prn[1]}  &\texttt{(\#1)}                                     &\text{round parens}\\
+\backslash\texttt{sqpr[1]} &\texttt{[\#1]}                                     &\text{square braces}\\
+\backslash\texttt{crl[1]}  &\{\texttt{\#1} \}                                  &\text{curly braces}\\
+\backslash\texttt{ceil[1]} &\backslash\texttt{lceil \#1} \backslash\texttt{rceil}&\text{ceiling}\\        
+\backslash\texttt{flr[1]}  &\backslash\texttt{lfloor \#1}\backslash\texttt{rfloor}&\text{floor}\\
+\backslash\texttt{ngl[1]}  &\backslash\texttt{langle \#1}\backslash\texttt{rangle}&\text{langle/rangle}\\
+\backslash\texttt{abs[1]}  &\backslash\texttt{vert \#1} \backslash\texttt{vert}  &\text{absolute value}\\
+\backslash\texttt{nrm[1]}  &\backslash\texttt{Vert \#1}  \backslash\texttt{Vert}    &\text{norm}\\
+\backslash\texttt{stgt[1]} &\texttt{< \#1>}                               & \text{lessthan greaterthan}
+\end{matrix}
+\end{equation*}
+
+\subsection{Adding ``b''s to change the size}
+Add one to four ``b''s to the end of a macro; each ``b'' raises size by one step. Example:
+\texttt{$\backslash$prnb$\{x\widehat\ 2-1\}$} gives $\prnb{x^2-1}$.
+
+\subsection{Adding ``l'' or ``r'' for one-sided delimiters}
+Prepend ``l'' (ell) or ``r'' to the front of the macro (after the backslash) for the single sided (\textbf{l}eft or \textbf{r}ight).  These macros take no parameter. Example: \texttt{$\backslash$lprnb}
+gives $\lprnb$.
+
+\subsection{Prepending a ``B'' for  boldface}
+Prepend a capital ``B'' to the front of the  macro for boldface (poor man's bold); if
+the macro is already a left or right, the ``B'' must preceed the ``l'' or ``r''. Needs a parameter if the
+non-bolded macro does. Example: \texttt{$\backslash$Blprnb} gives $\Blprnb$
+
+ \subsection{Warnings about paired delimeters}
+ The paired delimeter macros take as a single parameter the expression to be inside of the pair. 
+ Curley brackets around the expression will be essential here, as always in \LaTeX.
+ See the examples below.
+ 
+ Paired delimiters cause an error if the alignment ampersand \& is used between them.
+ The same issue arises with \texttt{$\backslash$left( --- \& -- $\backslash$right}), as you may have discovered.
+ There may be other formatting characters which break paired delimeters; please let me know if you
+ encounter an instance.
+ 
+ \subsubsection{Workarounds to the \& problem}
+ \begin{enumerate}
+ \item Rewrite. If you don't like the looks of
+ \begin{align*}
+ \int \text{A very very very very long  expression }&\le \text{ a shorter one}\\
+ &\le\text{ another short one}\\
+ &=\text{the final expression}
+ \end{align*}
+ perhaps you can break up the computations into smaller pieces so that you end with something like,
+ `` putting (3.12)-(3.36) together we see that
+ \[
+ \int \text{A very very very very long  expression }\le \text{the final expression}.\text{''}
+ \]
+ 
+ \item Use the left-right versions of the delimiters. They do not have the ampersand
+  problem that the two-sided versions and
+ $\backslash$\texttt{left\dots$\backslash$right} do.
+ 
+ \item Use $\backslash$\texttt{phantom}
+  \begin{verbatim}
+ &\int \text{A very very very very long  expression }
+      \le \text{ a shorter one}\\
+ &\phantom{\int \text{A very }}\le\text{the final expression}
+  \end{verbatim}
+  to get
+ \begin{align*}
+ &\int \text{A very very very very long  expression }
+      \le \text{ a shorter one}\\
+ &\phantom{\int \text{A very }}\le\text{the final expression}
+  \end{align*}
+ \end{enumerate}
+
+
+\section{Examples}
+\begin{enumerate}
+
+
+\item Here are two versions of the same display. The first uses $\backslash$\texttt{left $\backslash$right}; the
+second $\backslash$\texttt{sqprbbb}.
+I prefer the second one for being smaller, neater and using less typing. It's also much easier to change the size of the
+ second (add or remove a \texttt{b}) than the first (replace \texttt{$\backslash$left[...$\backslash$right]} with
+  \texttt{$\backslash$bigg[...$\backslash$bigg]}).
+ \[
+ \left[ \sum_n\frac{x_n}{y_n}\right]^{1/2}\quad \sqprbbb{\sum_n\frac{x_n}{y_n}}^{1/2}
+ \]
+ 
+ \item Bold vs. default:
+ \[
+  \Bprnbb{\frac x{x^2+1}} \quad  \prnbb{\frac x{x^2+1}} \quad
+  \Bcrlbb{\frac x{x^2+1}} \quad  \crlbb{\frac x{x^2+1}} 
+ \]
+ 
+ \medbreak
+ \item
+ \begin{verbatim}\sqprbbb{\int_a^b\prnbb{\frac{x+1}{x^2+5}}^p  dx}^{1/p}
+\text{,\  }\nrmbbbb{\crlbbb{\crlbb{\crlb{\crl{x-y}}}}}\text{ and } 
+  \lcrlbbbb\lsqprbbb\labsbb\lprnb \lngl
+  \end{verbatim}
+  \vskip-.3in
+  gives
+ \[
+ \sqprbbb{\int_a^b\prnbb{\frac{x+1}{x^2+5}}^p  dx}^{1/p} \text{,\  }\nrmbbbb{\crlbbb{\crlbb{\crlb{\crl{x-y}}}}}\text{ and } 
+  \lcrlbbbb\lsqprbbb\labsbb\lprnb \lngl
+ \]
+
+ \end{enumerate}
+ The \texttt{tex} source for this PDF contains more examples, commented out.
+ 
+ \section{Further comments}
+ \subsection{An alternate package, \textit{delim}}
+ The package \textit{delim} by Stefan Majewsky 
+ does things this one does, in a somewhat different way, and may be preferred by many \TeX\ users.
+ You can find this package by browsing CTAN under ``D''.
+ 
+ 
+ \subsection{Reversed parens}
+ At one time one saw open intervals expressed as
+ \[
+ \nrp{a,b} \quad\text{ or }\quad \rpqs{c,d}.
+ \]
+ This package provides paired delimeters at the 5 sizes, with and without bold face, for those two
+ situations. The macros are \texttt{$\backslash$nrp} and \texttt{$\backslash$rpqs}, followed by one to four 
+ ``b''s for  larger sizes and prepended by an optional  ``B'' for the bold face versions. No single sided 
+ reversed macros are given.
+ 
+ 
+ \subsection{Adding other delimiters}
+ Just copy the model here. In making the $\backslash$\texttt{B}... versions I have used 
+ $\backslash$\texttt{pmb} (poor man's bold)
+ throughout because $\backslash$\texttt{boldsymbol}, though recommended (e.g., by Gr\"atzer)
+ for many situations, 
+ does not work for all delimiters, while poor man's bold does.
+ 
+ 
+\subsection{Easy to remember sizers}
+\texttt{delimseasy} includes 
+versions of \LaTeX's 
+built-ins:
+\[\begin{matrix}
+\text{New}&\text{\LaTeX\ built-in}\\
+   &\texttt{$\backslash$big}\\
+\backslash\texttt{bigb}  &\texttt{$\backslash$Big}\\
+\backslash\texttt{bigbb} &\texttt{$\backslash$bigg}\\
+\backslash\texttt{bigbbb}&\texttt{$\backslash$Bigg}
+\end{matrix}\]
