<div class="block">This class represents an svcdump. It is the main class in the dumpreader package and
provides low-level access to the contents of an svcdump (eg the ability to read the contents
of an address in a given address space).
<p>
Implementation note: currently implemented by linking to the old svcdump.jar code (so you
need to include svcdump.jar when using) but this dependency will eventually be removed.</div>
