+\section{Overview}
+\ctsim\ is the graphical shell for the CTSim project. It is
 written using the wxLibrary for cross-platform compatibility with GTK,
 Motif, and Microsoft Windows. It includes all of the functionality of
-the command-line tool {\tt ctsimtext} as well as image processing and visualization features.

-\ctsim can open projection files, image files, phantom definition files, and plotfiles.

 \usage
 ctsim [OPTIONS] [files to open...]
 
+\section{Files Supported}
+\subsection{Phantom}
+Phantom files are supported. Besides loading phantom files from
+the disk, the Herman and Shepp-Logan phantoms are built-in to CTSim.
+Phantom files can be read and stored on the disk. However, a text
+editor is required to create and edit these files.
+ 
+\subsection{Image}
+Image files are 2-dimensional files stored a 4-byte floating point values.
+They are stored in little-endian format and \ctsim\ incorporates routines
+to read and write files correctly on both big and little endian architextures.
+
+Images files can be either real or complex valued. Typically, all images
+are real except for images that have been processed by Fourier transforms.
+
+\subsection{Projection}
+Projection files are created from Phantom files during the projection process.
+Numerous options are available for creation of the these files.
+
+\subsection{Plot}
+Plot files are created by CTSim during analysis of image files. They can be
+read and stored on the disk. They are stored as ASCII files for easy
+cross-platform support.
+
+\section{Phantom Menus}
+
+\subsection{Rasterize Dialog}
+This creates an image file from a phantom. Technically, it converts
+the phantom from a vector (infinite resolution) object into defined resolution
+image. The parameters to set are:
+
+x-size   Number of columns in image file
+y-size   Number of rows in image file
+samples  Numbers of samples taken per pixel in the x and y directions.
+         For example, if the nsamples is set to \texttt{3}, then for every
+         pixel in the image file, 9 samples (3 x 3) are averaged.
+
+\subsection{Projection Dialog}
+This creates a projection file from a phantom.
