\subsection{Detailed Description}
Interact with system dependencies.
This file holds the routines that interact with the system-dependent interface. This file essentially bridges the gap between the XML data and the hardware contained within the machine.
Definition in file {\bf sysdep.c}.

Convert sysdep device data into discover data under the \char`\"{}device\char`\"{} node.
Set up the toplevel data node.
Set up the first parent below \char`\"{}device\char`\"{} for this node.
Set up the token parser.
Split the node path by the path separator.
Set up the new data node.
Does this node have a predecessor in the path?
No; make it a child of the \char`\"{}device\char`\"{} node.
Yes; make it a child of the previous.
Clean up after the token parser.
