Creating Exports and Imports file for shared library

[David_Alan_Lee at cup.portal.com]

I am trying to create a shared library on AIX RS/6000 and I am having 
trouble finding the best way to create the exports and imports files.
Currently I am running /usr/ucb/nm on my non-shared library and grep'ing
for global text and data symbols, however I get duplicate definitions,
like:

Function   
.Function

Which of these should be used for an import or export file? (if either)
Does anyone have any suggestions on the "best" way to generate the 
list of exported and imported symbols for a shared library?
I know that once I already HAVE a shared libary (like /lib/libc.a) I 
can use dump -Tv library | awk '$2 == "EXP" {print $8}' , but 
I don't know what to do on a non-shared library.
Any suggestions would be greatly appreciated.
