# Bob Ippolito:
"""
Ok.. the code to find the filename for __getattr__ should look
something like:

import os
from macholib.dyld import dyld_find

def find_lib(name):
     possible = ['lib'+name+'.dylib', name+'.dylib',
     name+'.framework/'+name]
     for dylib in possible:
         try:
             return os.path.realpath(dyld_find(dylib))
         except ValueError:
             pass
     raise ValueError, "%s not found" % (name,)

It'll have output like this:

 >>> find_lib('pthread')
'/usr/lib/libSystem.B.dylib'
 >>> find_lib('z')
'/usr/lib/libz.1.dylib'
 >>> find_lib('IOKit')
'/System/Library/Frameworks/IOKit.framework/Versions/A/IOKit'
