-\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:
+\subsection{Adding ``b''s to change the size; ``D''s to use \LaTeX\ default}
+Add one to four ``b''s to the end of a command; 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 $\lprnb$.
+Save typing by prepending ``D'' to the start of a 
+command to use the \texttt{$\backslash$left$\dots\backslash$right}
+default sizing provided by \LaTeX. 
+Example: \texttt{$\backslash$Dprn$\{x\widehat\ 2-1\}$} gives
+ $\Dprn{x^2-1}$ while \texttt{$\backslash$Dprn$\{x-1\}$} gives $\Dprn{x-1}$. 
+
+\subsection{Adding ``L'' or ``R'' for one-sided delimiters}
+Prepend upper or lowercase ``L''  or upper or lowercase 
+``R'' to the front of the command (after the backslash) for the single 
+sided (\textbf{L}eft or \textbf{R}ight).  
+These commands take no parameter. Example: \texttt{$\backslash$Lprnb}
+gives $\Lprnb$. 
+
+There are no  one-sided versions of the \texttt{$\backslash$D...} commands.
 
 \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.
+This is not available for the $\backslash$\texttt{D\dots} commands.

+ ampersand \& is used between them.
+ There may be other formatting characters which break 
+ paired delimeters; please let me know if you

 \section{Examples}

-\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]}).
+\item Here are two versions of the same displays. 
+The first pair uses $\backslash$\texttt{left $\backslash$right} (implemented through $\backslash$\texttt{Dsqpr}

+I prefer the second pair for being using less vertical space and being more easily  resizable than the first.

+ \subsection{Bionomial coefficients  and reversed delimiters}
+  
+ Binomial coefficients often display with overly large parens. Versions under your control

- \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.

+ To make your own delimiter pairs, just adapt the models in the 
+ \texttt{sty} file. 
+ Note that the $\backslash$\texttt{B}... versions use
  $\backslash$\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.
- 
+ throughout because $\backslash$\texttt{boldsymbol}
+ does not work for all delimiters, while  $\backslash$\texttt{pmb}
+ does. Some ``delimiters'' may not have 
+ $\backslash$\texttt{big}(ger) versions so you will have to improvise, as here for
+  $\ll\dots\gg$.
+The larger versions of  $\ll\dots\gg$  do not look great; they merely illustrate what can be naively
+ achieved.
  
+ The  two Valentine delimiters  must be in Math mode. If your beloved's name has spaces, 
+ you will need to protect
+ the space(s) by preceding each one with
+  a $\backslash$\texttt{backslash} since
+ Math mode ignores unprotected spaces. The Valentines commands can be nested at least once:
+ \[
+\valentine{\ \diamondsgbf{\ Kim\ }\ }\qquad {\diamondsgbf{\ \valentine{Leslie}\ }}
+\qquad\valentine{\valentine{\valentine{\ \valentine{ Deniz }\ }}}.
+\]
+ Adjusting the space in the various pairs with $\backslash{\ }$'s  may improve the look.

+Added ``D'' versions for those who prefer \LaTeX's choice for sizing.
