Uninstallin Flashplayer?

[Leonard Chatagnier]

Instructions for installing the new alpha tar.gz for the 64 bit adobe flashplayer says:
"Important: All users should uninstall any currently installed Flash Player before installing the latest prerelease."

I'm wondering if there is any more to it than just rming the file, libflashplayer.so, from the system. The current adobe flashplayer was installed with "flashplugin-nonfree" on Intrepid, up to date, on a fresh install, not upgraded, using the alternate AMD64 CD.
Any enlightenment is most welcome as I have downloaded the new alpha version, extracted it and only the libflashplayer.so file was found. No readme or bin files were found.
