## \subsection*{Purpose}
## Convert from HIPS to VIFF (Khoros) format
## 
## \subsection*{Usage }
## \begin{verbatim}
## hips2viff [-byte|-int|-float|-scale]
## \end{verbatim}
## \begin{description}
##   \item[-byte]
## 	Convert using byte format
##   \item[-int]
## 	Convert using integer format
##   \item[-float]
## 	Convert using floating point format
##   \item[-scale]
## 	Convert using byte format, scaled to the maximum dynamic range
## \end{description}
