-The CGI program \texttt{ctsim.cgi} takes projections of a standard
-phantom object, performs reconstruction, and then compares the
-rasterized phantom object with the reconstruction. The comparison is
-performed both visually by an image subtraction as well as by standard
-statistics as described by Herman\cite{HERMAN80}.
