<title>Introduction to <application>GStreamer</application></title>

<para>The <application>GStreamer</application> package contains a streaming 
media framework that enables applications to share a common set of plugins for 
things like video decoding and encoding, audio encoding and decoding, audio 
and video filters, audio visualisation, Web streaming and anything else that 
streams in real-time or otherwise. It is modelled after research software 
worked on at the Oregon Graduate Institute.</para>

<para><parameter>--localstatedir=/var</parameter>: This switch puts 
<command>gst-register</command>'s cache in 
<filename class="directory">/var/cache/gstreamer-0.8</filename> 
instead of 
<filename class="directory">/usr/cache/gstreamer-0.8</filename>.</para>

<para><parameter>--sysconfdir=/etc</parameter>: This switch puts configuration 
files in <filename class="directory">/etc</filename>

<para><option>--disable-docs-build</option>: This switch prevents
the rebuilding of documentation during the <command>make</command>
command.</para>

<para><command>chown -R root:root ...</command>: The documentation is 
installed with ownerships of the user who untarred and built the package. 
This command changes the ownerships of the installed documentation files to
