+\subsection{The SICS Help System}
+SICS has a very simple help system. It is based on plain text files
+containing the help texts. There is a default help file which is
+printed when help is called without arguments. Other help files are
+printed by the command: help name. The name of the text file is then
+name.txt. This file is earched in a configurable small set of
+directories. This allows to separate general SICS help files and
+instrument specific help files.
+
+This system is implemented as a module defined in help.c. The
+interface is simply the interpreter function implementing the help
+command. There is also a function for removing the data associated
+with help.
