I have two questions:
	1. I'd like to create a file package similar to Librarian.app for an application I'm writing, 

so I can include a help file in the package.  I couldn't find any documention on how to
 actually create a file package, so I just made a directory called Myapp.app, and put the
 executable Myapp together with the help file in Myapp.app. That seems to work ok - when
 I double click on Myapp.app the correct application starts up. However,  the icon
 associated with Myapp.app is the generic application icon rather than the custom one I 

associated with Myapp. So what I'd like to know is, 1) how do you get a  custom 

application icon to be associated with the file package,  and 2) is there some other way I'm 

supposed to create file packages?

        2. When I do NXMapFile(filename, NX_WRITEONLY), the routine fails (ie can't open 

filename) unless it already exists. So  I have to create an empty file with standard Unix 

commands first, after which the routine works. This doesn't seem to be the behaviour you'd
 want - so is this a bug or a feature, or am I doing something wrong?

Thanks
