I and Sylvain Le Gall just released OASIS 0.4.5.
    OASIS is a tool to help OCaml developers to integrate
      configure, build and install systems in their projects. It should
      help to create standard entry points in the source code build
      system, allowing external tools to analyse projects easily.
    
    
      
      Important changes:
      * Build and install annotation files.
      * Use builtin bin_annot and annot tags.
      * Tag .mly files on the same basis as .ml and .mli files (required
      by menhir).
      * Remove 'program' constraint from C-dependencies. Currently, when
      a library has C-sources and e.g. an executable depends on that
      library, then changing the C-sources and running '-build' does not
      yield a rebuild of the library. By adding these dependencies
      (rather removing the constraint), it seems to work fine.
      * Some bug fixes
      
Features:
        * no_automatic_syntax (alpha): Disable the automatic inclusion
        of -syntax camlp4o for packages that matches the internal
        heuristic (if a dependency ends with a .syntax or is a well
        known syntax).
        * compiled_setup_ml (alpha): Fix a bug using multiple arguments
        to the configure script.
