+This small package use the pgfkeys pacakge to solve the problem of
+using the ]a,b[ syntax for indicating an open interval. Instead of
+having to type this as \mathopen{]}a,b\mathclose{[} users can simply
+use
+
+  \interval[open]{a}{b}        (= ]a,b[ with proper spacing)
+
+Other usages include
+
+  \interval[open left]{a}{b}   (= ]a,b])
+  \interval{a}{b}              (= [a,b])
+
+We also provide a simple interface to switch to the more convenient
+(a,b) tradition for specifying an open interval.
+
+See the manual for details.

+\item[colorize]
+  Default: \meta{empty}. When rewriting an existing document into
+  using the \textsf{interval} package, it turns out to be \emph{very}
+  handy to color the result of the \cs{interval} macro to keep track
+  of which have been rewritten and which has not.
+  This can be done using
+\begin{lstlisting}[basicstyle=\ttfamily,columns=flexible]
+  \usepackage{xcolor}
+  \intervalconfig{ colorize=\color{red} }
+\end{lstlisting}
+It will colorize the entire interval including the fences.
