 \section{Overview}
-\ctsim\ can also be executed via a web browser. The CGI program
+\ctsim\ can also be executed via a web browser. The Perl 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 statistical
 analysis.
 
+The \texttt{ctsim.cgi} program is invoked from the HTML file
+\texttt{simulate.html}.
