ocamlspotter support in core

[Jun Furuse]

Hi,

It is now rather off-topic and non related with core, but

If you set OCAML_ANNOT environment variable with something non-empty,
the patched compiler creates .annot/.spot/.spit files automatically
even w/o -annot option. Thus I compile OCaml library packages with
annot/spot/spit files even if the build scripts are not with -annot.

Installation of spot/spit files of such packages untouching the build
scripts is bit more tricky. I have written a small tool automatically
finds those in source directories and copy into ocamlfind destdirs. It
is not documented at all but you can try it:

  https://bitbucket.org/camlspotter/spotinstall  (It requires
https://bitbucket.org/camlspotter/spotlib)
