package ij;
import java.applet.Applet;

    Runs ImageJ as an applet and optionally opens up to 
    nine images using URLs passed as a parameters.
    Here is an example applet tag that launches ImageJ as an applet
    and passes it the URLs of two images:
    &lt;applet archive="../ij.jar" code="ij.ImageJApplet.class" width=0 height=0&gt;
    &lt;param name=url1 value=""&gt;
    &lt;param name=url2 value=""&gt;
    To use plugins, add them to ij.jar and add entries to IJ_Props.txt file (in ij.jar) that will  
    create commands for them in the Plugins menu, or a submenu. There are examples 
    of such entries in IJ.Props.txt, in the "Plugins installed in the Plugins menu" section.
    Macros contained in a file named "StartupMacros.txt", in the same directory as the HTML file
    containing the applet tag, will be installed on startup.
