[p4] [OS X]Exclude ~.nib directories

[David]

I would like to exclude directories and their contents from a Mac OS  
X project that include directories that end in "~.nib" such as  
"MyDialog~.nib".  But I also need to include files and directories  
that end in ".nib".  The only exclude line I was able to add to my  
workspace view to remove the "~.nib" directories also removed the  
directories ending in ".nib".

Is the a exclude spec I can use that will work for this?

Thanks.
