ZIP archives

I am wanting to implement in my app the ability to create 
standard .zip archives.  I have looked through the list archives and 
read various things on the internet, but I'm rather confused :(

Thus far my research has uncovered to me:

zlib - pre-installed with OS X.  Does not support .zip archives, but 
there is add-on code to do it.

gzip - Also doesn't support .zip archives

info-zip - As far as I can tell, this is an open source command line 
tool, rather than a library I can use.


So, what would people recommend for Cocoa use?  Should I use NSTask 
to have a command line tool handle the thing for me?  Or should I use 
a library like zlib?  Or is there something better that I've missed 
altogether!?
