Flash player re-packaging & install preparation

Can we get a consensus opinion about what version/parts of Flash Player get installed with Tiger - 10.4.11 PPC Tiger - 10.4.11 x86 Leopard - 10.5.2 The /Library/Internet Plug-ins folder appears to have a functional Flash player in it - in the form of Flash Player.plugin, Flash Player Enabler.plugin (Tiger PPC only?), and flashplayer.xpt. In an effort to find the 'best practice way' of re-packaging the Flash Player installer, I have a feeling a preflight script must be written to clean up these files but am not certain. Anyone have thoughts on this?
