Re: Incrmental indexing

I'm sorry, I must have misunderstood the question. Timo, were you asking 
how to get the --enable-incremental option to compile? Or how to use it?

See this mail thread:

I think basically you need to compile with --enable-incremental, then 
use the -u option (probably with -N to update files newer than some date 
-- usually the timestamp of the index, I would guess).

I think this is, in effect, similar to the -N/-M scenario I described 
before, but does it in one step instead of two. Please, someone who 
wrote the code (Jose? Bill?), correct me on this.
