[MS4W-Users] FileGDB tip for MS4W 4.0 users

[Jeff McKenna]

For the record, here is an explanation of those parameters for each driver:

• "ro" means read-only
• "rw" means read and one-time creation only
• "rw+" means read, create and update
• "v" means that it supports virtual files

I am going to add this into the MS4W README, and I have filed a ticket 
for this so it is tracked (http://ms4w.com/trac/ticket/71).

If you or anyone else notices any text that can be added to the MS4W 
documentation, please do create a ticket and include what you need 
added.  Thank you.
