+//var AMTcgiloc = "http://www.imathas.com/cgi-bin/mimetex.cgi?"; //path to CGI script that
+//						     //can render a TeX string
+//
+// You should pick up and install on your server software for TeX rendering as:
+//
+// mimeTeX - http://www.forkosh.dreamhost.com/source_mimetex.html
+// mathTeX - http://www.forkosh.com/mathtex.html
+//
+// or you may try to use some public services as:
+//
+// MathTran - http://www.mathtran.org/
+// Google Chart Tools - http://code.google.com/apis/charttools/
+//
+// You have to set here the path to the script for TeX rendering
+// and query parameters, if any.
+//
+// Examples:
+//
+// var AMTcgiloc = "/cgi-bin/mimetex.cgi?";
+// var AMTcgiloc = "http://my_server.net/cgi-bin/mimetex.cgi?";
