<p>
This plugin reads data from a custom GIO <a href="http://library.gnome.org/devel/gio/unstable/GInputStream.html"><span class="type">GInputStream</span></a>.
</p>
<p>
It can, for example, be used to read data from memory with a
<a href="http://library.gnome.org/devel/gio/unstable/GMemoryInputStream.html"><span class="type">GMemoryInputStream</span></a> or to read from a file with a
<a href="http://library.gnome.org/devel/gio/unstable/GFileInputStream.html"><span class="type">GFileInputStream</span></a>.
