[AccessD] Import/Export Specifications - Basic questions

I've faced this same "pain": the import file gets changed (unknowingly) and
now the import references gets all messed up....and of course, the entire
system you built...crashes.
Below is good advice. Modifying the system specs sounds easy...but IT IS NOT
!

> Just start a manual import as usual, select the import spec you want to
> modify, which does most of the hard work for you, and then make changes
> to it as needed. Finally save it with a different name with the 'Save
> As' button on the Import Specification dialog box.
