\begin{document}
82
The \autodoc:package{pullquote} package formats longer quotations in an indented blockquote block with decorative quotation marks in the margins.
83
Here is some text set in a \autodoc:environment{pullquote} environment:
84

85
\begin[author=Anatole France]{pullquote}%
86
An education is not how much you have committed to memory, or even how much you know.
87
It is being able to differentiate between what you do know and what you do not know.
88
\end{pullquote}
89

90
Optional values are available for:
91

92
\begin{itemize}
93
\item{\autodoc:parameter{author} to add an attribution line}
94
\item{\autodoc:parameter{setback} to set the bilateral margins around the block}
95
\item{\autodoc:parameter{color} to change the color of the quote marks}
96
\item{\autodoc:parameter{scale} to change the relative size of the quote marks}
97
\end{itemize}
98

99
If you want to specify what font the \autodoc:environment{pullquote} environment should use, you can redefine the \autodoc:command{\pullquote:font} command.
100
By default it will be the same as the surrounding document.
101
The font style used for the attribution line can likewise be set redefining \autodoc:command{\pullquote:author-font}, and the font used for the quote marks can be set redefining \autodoc:command{\pullquote:mark-font}.
