I would like information and leads on change-control software.  One of our 
publication groups stores files on a Macintosh server, and we would like to 
have some control of who can do what with the files.  For example, we would 
like a writer to be able to check out a file, but keep the file on the server 
as read-only until it is checked back it.  We'd also like to have some way of 
keeping track of who checks the files in and out, and when they are checked in 
and out.  

If you have any information on software that does this, please send me email 
at one of the addresses below.  I'll summarize and post if interest warrants.
