Re: [Caml-list] Speeding up compilation

[Francois Berenger <berenger@riken.jp>]

I've had good experience shifting all my projects from whatever they
were using to obuild[1]. ;)

More seriously (yeah, shameless plug...), I have heard that people
handling a lot of OCaml source files and interested in fast compilation
use omake[2].

I also heard that there is an incremental build feature in merlin[3].

I did not try omake because I am too lazy to learn a new
syntax to describe my build.
I tried merlin, but it made my Emacs lag, so I removed it
quickly after a few days of trial.
