The \texttt{btrecord} and \texttt{btreplay} tools provide the ability to
record and replay IOs captured by the \texttt{blktrace} utility. Attempts
are made to maintain ordering, CPU mappings and time-separation of IOs. The
general workflow is expected to be:

\begin{enumerate}
  \item Initiate \texttt{blktrace} to capture traces
  \item Generate traces\ldots
  \item Stop \texttt{blktrace}
  \item Run \texttt{btrecord} to convert traces into IO records 
  \item Utilize \texttt{btreplay} to replay IOs 
\end{enumerate}

This document will discuss the operating characteristics of
\texttt{btreplay} and provide detailed command line option descriptions.
