[Install.]addDirectory

The Install object's addDirectory method queues an entire directory for installation once performInstall is called.

 var vi = "10.10.10.10";
 var xpiSrc = "adddir1";
 
 initInstall("addFileNoVers1", "adddir_1", vi, 1);
 
 f = getFolder("Program");
 setPackageFolder(f);
 err = addDirectory(xpiSrc);	 	 	 	 
 logComment("the error = " + err);
 
 if (0 == getLastError())
    performInstall();
 else
    cancelInstall();
