Re: How to parse a text file

I did parse a 100Mb file once (into a NSString) when I wanted to do like a
quick and dirty semi-database thing. Ok, it wasn't that fast (for obvious
reasons) but it did work.

I think even NSMutableString would handle such a large file. I'm not sure if
I tried that in the same spin as above, but I do know of someone who did (if
I'm not completely wrong).
