Place the file "revAltPlugin.rev" into your plugins folder. When it launches, it creates a folder "altPlugs" where you can place all of the *new* altPlugins.

Note: If you are a previous user of altPlugin, you may see another folder in the RunRev plugins folder named "altPlugins." You should delete this folder and its contents and install the new 'versioned' altPlugins. Launch RunRev and the altPlugin toolbar will install itself and auto-load any plugins it finds in the new "altPlugs" folder.
