The "data index" is mentioned in the R Extensions Writer guide as

Now since this is now required,  
what is the format of that file? what must/should it contain?
Shouldn't this be built automatically from the data's *.Rd files when it
doesn't exist?

Thanks for any clarification; the requirement of this 00Index has been new
for me (must have slept at some time in the past...).

Martin.
