How to use nspluginwrapper

[Eduardo Cerejo]

It's been a while since I used this and decided to use it again because gnash looks like is getting harder to use and becoming very buggy.

I've installed linu-flashplugin and now I want to installed the plugin using nspluginwrapper and I've trying to install it like this:

nspluginwrapper -i /usr/local/lib/npapi/linux-flashplugin/libflashplayer.so

but it doesn't install it, what is the right way of doing it?
