MacOS X plugin sample

Hi,

I have to implement a firefox plugin on MacOSX. I've checked out the 
cvs and build the samples but no one worked yet.

I put the sample Defaut\ Plugin.plugin in my /Library/Internet\ Plugin/ 
and Firefox doesn't detected it.

Does anyone have a little sample which just show me how build a plugin 
(Mach-O or CFM) and how install it ?

Thanks,
