% \section{Usage}
-% You just have to type intervals in an easy way:
-% |$x\in]0,\pi[\cup]2\pi, 3\pi[$|
-% produce
-% \[ x\in]0, \pi[\cup]2\pi, 3\pi[ \mbox{\quad with \textsf{ibrackets}}, \]
-% instead of
-% \[ x\in\mathclose{]} 0,\pi \mathopen{[}\cup\mathclose{]} 2\pi, 3\pi\mathopen{[}
-% \mbox{\quad without \textsf{ibrackets}}.
-% \]
+% With the \textsf{ibrackets} package, you can easily type intervals. For example the code
+% |$x\in]0,\pi[\cup]2\pi, 3\pi[$| yields
+% \begin{align*}
+% x\in]0, \pi[\cup]2\pi, 3\pi[ &\mbox{\quad with \textsf{ibrackets}}, \\
+% \text{instead of \quad}
+% x\in\mathclose{]} 0,\pi \mathopen{[}\cup\mathclose{]} 2\pi, 3\pi\mathopen{[}
+% &\mbox{\quad without \textsf{ibrackets}}.
+% \end{align*}
%
-% Generally $[$ and $]$ symbols are not defined anymore as delimiters,
-% but as ordinary characters.
-% Thereby a line break could occur between the two square brackets, but
-% it is always possible to transform them
-% into delimiters with |\left| and |\right|.
+% For the example in the introduction the spacing is now correct with the following simple code:
+% |$x \in ]-\infty, 0]$|, which gives $x \in ]-\infty, 0]$.
%
% \medskip
-% The problem of a sign following the first bracket is solved with this package,
-% so the example in the introduction is simply obtained with |$x \in ]-\infty, 0]$|
-% which gives $x \in ]-\infty, 0]$.
+% In \textsf{ibrackets}, the symbols $[$ and $]$
+% and are not defined by default as delimiters.
+% Therefore, a line break could occur between the two brackets. However,
+% it is always possible to transform them
+% into delimiters using |\left| and |\right|.
%
% \medskip
-% \emph{However, you don't have to leave a space between the first bracket and the sign}: e.g.\@
-% |$x \in ] -\infty, 0]$| yields $x \in ] -\infty, 0]$ with bad spacing around the
-% minus sign.
-% Contrariwise, when you want to write algebra on intervals then
-% \emph{you must leave a blank space between the second bracket and the} +/- \emph{operations},
-% e.g.\@ |$[a, b] + [c, d]$| yields $[a, b] + [c, d]$
-% but |$[a, b]+ [c, d]$| yields $[a, b]+ [c, d]$.
-% To summarize the new behavior of a bracket: it is an ordinary character,
-% but an open delimiter when it is immediately followed by a + or - character.
+% Actually, brackets are set as ``active'' characters,
+% behaving like ordinary characters in most cases.
+% However, when a bracket is \emph{immediately} followed by a + or - character,
+% it becomes an open delimiter. Therefore, when the left bound contains an operator sign,
+% \emph{you don't have to leave a space between the first bracket and the sign},
+% otherwise, the spaces surrounding the operator will be too large.
+% For example if you write |$x \in ] -\infty, 0]$| it yields $x \in ] -\infty, 0]$
+% instead of $x \in ]-\infty, 0]$.
+% Conversely, when dealing with algebraic expressions involving intervals,
+% \emph{you must leave a space between the second bracket and the} +/- \emph{operations}
+% to maintain proper spacing.
+% For instance |$[a, b] + [c, d]$| yields $[a, b] + [c, d]$
+% while |$[a, b]+ [c, d]$| would yield $[a, b]+ [c, d]$.
