+\maketitle
+\begin{abstract}
+The \textsf{bropd} package simplifies the process of writing differential
+operators and brackets in \LaTeX. The commands facilitate the easy manipulation
+of equations involving brackets and allow partial differentials to be expressed
+in an alternate form.
+\end{abstract}
+\section{Introduction}
+The \textsf{bropd} package introduces a bracket command that automatically
+selects parentheses, square brackets or braces as appropriate based on the
+number of brackets. As such, brackets can be freely added and removed without
+alterations to the rest an equation. A command for writing ordinary and partial
+differentials is also created with an optional concise form for typesetting
+partial derivatives. This allows equations to be typed in a standard form and
+their style altered globally at a later date.
+\section{Usage}
+This section outlines the use of the three commands provided by the
+\textsf{bropd} package.
+\subsection{Brackets}
+The bracket command replaces \verb|\left(| and \verb|\right)| with the single
+command, \verb|\br| to produce brackets in a math environment. The input
+\verb|\br{x}| produces\[\br{x}.\]When nested, the type of bracket is determined
+automatically, for example, \verb|r=\br{\br{x-a}^2+\br{y-b}^2}^{\frac{1}{2}}|
+results in\[r=\br{\br{x-a}^2+\br{y-b}^2}^{\frac{1}{2}}.\]
+\subsection{Differential operators}
+\subsubsection{Ordinary differential}
+The \verb|\od| command produces ordinary differentials, such as \verb|\od{y}{x}|
+which is displayed as\[\od{y}{x}.\]The order of the differential can be
+specified as an optional argument, illustrated here with the command
+\verb|\od[2]{u}{x}=-\omega^2u| which results in\[\od[2]{u}{x}=-\omega^2u.\]When
+using \verb|\od| with a sans-serif font, the package should be loaded with the
+optional argument \verb|sans|.\subsubsection{Partial differential}The command
+\verb|\pd| follows the same form as \verb|\od|, but instead produces partial
+differentials. By default \verb|\pd{u}{t}=6u\pd{u}{x}-\pd[3]{u}{x}|
+produces\[\pd{u}{t}=6u\pd{u}{x}-\pd[3]{u}{x}.\]Loading the package with the
+option \verb|pdshort| results in an alternative format for partial
+differentials:\[u_t=6uu_x-u_{xxx}\]Note that when using this form, the
+\verb|\br| function \emph{must} follow \verb|\pd| when the first argument is
+left empty, as demonstrated by \verb|\pd{}{z}\br{x+y}| which results
+in\[\br{x+y}_z.\]If the optional argument is not a positive integer, the default
+form is reverted to, as with \verb|\pd[n]xy|:\[\pd[n]xy\]The syntax for partial
+differentials is extended to allow the second order term such
+as\[\pd{u}{x,t}\]to be easily typeset with \verb|\pd{u}{x,t}|.
+\subsection{Further examples}
+Combining the commands provided by this package allows more complex terms to be
+written concisely. The \verb|\br| allows equations with multiple brackets to be
+constructed and manipulated quickly and easily. An example of this is
+\verb|\br{x-y}\br{Q-\frac12\br{P+\br{x-1}\br{\br{A+B}\br{u+c}-t}}}|, which
+results in\[\br{x-y}\br{Q-\frac12\br{P+\br{x-1}\br{\br{A+B}\br{u+c}-t}}}.\]
+The form of the partial differentials written with the \verb|\pd| command can be
+changed at any time.\verb|\pd Et+\sum_{i=1}^3\pd{}{x_i}\br{\br{E+p}u_i}|
+produces\[\pd Et+\sum_{i=1}^3\pd{}{x_i}\br{\br{E+p}u_i}\]
+or, with \verb|pdshort|,\[E_t+\sum_{i=1}^3\br{\br{E+p}u_i}_{x_i}.\]
