Hello,

I'm new to Boost.Build and after reading the documentation and
experimenting with simple examples I'm willing to use it in a real
project. I've managed to deploy a Boost.Build build system but was
wondering myself if I was doing things right.

Here is the project tree :

top/
  |
  +-- configure
  |
  +-- user-config.jam
  |
  +-- Jamroot
  |
  +-- network/
  |    |
  |    +-- Jamfile
  |    `-- network.cpp
  |    `-- network.hpp
  |
  `-- core/
       |
       +-- Jamfile
       `-- core.cpp

The idea is that core is the main function and network a network class
using Boost.Asio that is to be used by the core function.

The configure script generates the user-config.jam file with
informations on various library locations (boost and pthread for now).

Then the Jamroot file builds the core module which depends on network.
Therefore network is built as a static library which is linked with
core. I need network to be a library because it will be reused in other
projects.

As I said, I've managed to get everything working but I find the way I
did it a bit crappy (may be I'm just not used to Boost.Build yet).
Espcially the way I did the user-config.jam file, however I didn't find
any other method.

Thanks in advance !

Here are the jam files :
