+\subsection{Amor Scan}
+This is a special adaption of the general scan routines for the
+reflectometer AMOR at SINQ. It works by replacing the configurable
+routines in the general scan command with special ones, suited to the
+reflectometers purpose. There are several adaptions to the standard
+scan command:
+\begin{itemize}
+\item Data is written to NeXus files instead of ASCII files.
+\item There are two counters to keep track of. 
+\item Furthermore stubs are provided for dealing with spin flippers.
+\end{itemize}
+
+In order to keep track of counters and monitors the following
+convention has been devised:
+\begin{itemize}
+\item GetCounts gets the main detector.
+\item GetMonitor 0 the second detector
+\item GetMonitor 1 the first detector other spin
+\item GetMonitor 2 the second detector other spin
+\item GetMonitor 3 the first monitor
+\item GetMonitor 4 the second monitor
+\end{itemize}
+Thus the monitor channels are used to keep the additional counter
+information. 
+
+This module provides only one external function:

+\begin{list}{}{\setlength{\itemsep}{-\parsep}\setlength{\itemindent}{-\leftmargin}}
+\item Macro referenced in scrap ?.
+\end{list}
+\end{minipage}\\[4ex]
+\end{flushleft}
+which configures the variable fields and function pointers in pScan to
+functions defined in this module. These then do the right thing. This
+module is also an example of how the scan command can be configured to do
+tricks based on the syntax and  hooks defined in scan.*.
