// Note added 12:41 PM 9/21/2008 by Bob Hanson, hansonr@stolaf.edu:

// JMOLJAR=xxxxx.jar on the URL for this page will override

// the JAR file specified in the jmolInitialize() call.

// The idea is that it can be very useful to test a web page with different JAR files

// Or for an expert user to substitute a signed applet for an unsigned one

// so as to use a broader range of models or to create JPEG files, for example.

// If the JAR file is not in the current directory (has any sort of "/" in its name)

// then the user is presented with a warning and asked whether it is OK to change Jar files.

// The default action, if the user just presses "OK" is to NOT allow the change. 

// The user must type the word "yes" in the prompt box for the change to be approved.

// If you don't want people to be able to switch in their own JAR file on your page,

// simply set this next line to read "var allowJMOLJAR = false".
