\section{Introduction}
The \texlabel{} package allows you to label parts of your document
just like labelling e-mail.

\section{Usage}
You can use the \labelscom{} command when you want to label some part of
your document. The labels remain effective until you issue the next
\labelscom{} command.

\section{Example}
See tex-label-demo.tex and tex-label-demo.pdf

\section{Customizing}
You can change the color of label text and label background by
redefining {\em label-color} and {\em label-bg-color} respectievely. 

For ex:- to redefine label text to white use

\begin{verbatim}
\definecolor{label-color}{rgb}{1,1,1}
\end{verbatim}
