\section{Installation}
To Build Diskmodel:

1.  build libparam and libtrace 

2.  edit .paths in the diskmodel source directory to reflect where
you built libparam and libtrace

3.  'make' in the diskmodel directory

\section{Typical use with libparam}

'make all' sets up include and lib subdirectories such that
you may use 
\begin{verbatim}-I$(DISKMODEL_PREFIX)/include \end{verbatim}
with the preprocessor and 
\begin{verbatim}#include<diskmodel/dm.h> \end{verbatim} etc.  Similarly, 
\begin{verbatim}-L$(DISKMODEL_PREFIX)/lib -ldiskmodel \end{verbatim} 
with the linker where \texttt{DISKMODEL\_PREFIX} is the top-level
source directory where you built diskmodel.


1.  register diskmodel libparam modules with libparam. e.g.
\begin{verbatim}
#include <diskmodel/modules/modules.h>
for(i = 0; i <= DM_MAX_MODULE; i++) {
  lp_register_module(dm_mods[i]);
}
\end{verbatim}

2.  use \texttt{lp\_loadfile()} to load a model file

3.  use \texttt{lp\_instantiate()} to instantiate a model from the
input file.  The result of the instantiation is a \texttt{struct
dm\_disk\_if *}

e.g. \texttt{struct dm\_disk\_if *disk = lp\_instantiate(...);}


4.  Access methods through d.
e.g. \texttt{dm\_time\_t seektime = d->mech->dm\_seek\_time(...)}
