We download the non-rpm version (for historical reasons and because we 
need to have several different versions of the JRE/JDK installed), and 
then just make symlinks from the mozilla-seamonkey and firefox plugins 
trees (because that is how we have always done it)...

e.g. for firefox we do
...
   my $moz_inst="/usr/lib/firefox-$mver";
...
    (hackery for lib64 stuff)
...
   chdir($moz_inst) || die ("Can't chdir to $moz_inst: $!");
...
   for $targ (keys(%elinks)) {
...
     symlink($elinks{$targ}, $targ);
...

where for plugins/libjavaplugin_oji.so that currently points off at 
/opt/sunjava/jre1.6.0_01/plugin/i386/ns7/libjavaplugin_oji.so

We do the same process for mozilla-seamonkey except that obviously 
$moz_inst starts off being /usr/lib/mozilla-$moztype-$mver or something...

What is the /usr/lib/mozilla/plugins/ tree for?  Stuff that is shared by 
*both* firefox and mozilla or something else?
