\title{A Sample Document Using glossaries.sty}
\author{Nicola Talbot}
\maketitle
\begin{abstract}
This is a sample document illustrating the use of the \textsf{glossaries}
package. The functions here have been taken from ``Tables of
Integrals, Series, and Products'' by I.S.~Gradshteyn and I.M~Ryzhik.
The glossary is a list of special functions, so
the equation number has been used rather than the page number. This
can be done using the \texttt{counter=equation} package
option.

\chapter{Gamma Functions}
\begin{equation}
\gls{Gamma} = \int_{0}^{\infty}e^{-t}t^{z-1}\,dt
\end{equation}
\verb|\ensuremath| is only required here if using
hyperlinks.
\begin{equation}
\glslink{Gamma}{\ensuremath{\Gamma(x+1)}} = x\Gamma(x)
\end{equation}
\begin{equation}
\gls{gamma} = \int_0^x e^{-t}t^{\alpha-1}\,dt
\end{equation}
\begin{equation}
\gls{iGamma} = \int_x^\infty e^{-t}t^{\alpha-1}\,dt
\end{equation}
\newpage
\begin{equation}
