= Implementing CMT2 on top of Waf

Principle:
 * every package is still packaged using the CMT style:
   * a `cmt` directory with its `requirements` file
     * the `requirements` files hold:
       * used packages
       * declarations of the constituents (libraries, programs, ...)
       * specific macro declarations
   * a `src` directory containing the sources
 * the Project still contains a `cmt` directory with its own `requirements` file
   * this `requirements` holds:
     * the list of used packages of the projects
     * generic macro definitions

Only one generic `wscript` is needed for managing the whole project.

{{{

import sys
import os

import cmt

top, out = cmt.init ()

def options (ctx):
  cmt.options (ctx)

def configure (ctx):
  cmt.configure (ctx)

def build (ctx):

the build is launched using:

{{{
