Hi, The section of the docs '1.1 The problem' shouldn't be focussed on how C++ doesn't have system calls built in, as this is a problem that the whole of boost is addressing, not just this library. It should be more like the introduction to lexical cast, where a short history of what was available in C,C++ is given. The short history and the shortcomings of whats gone before would be platform specific. The last bit starting 'One of these is process management' is relevant but the previous 3 paragraphs aren't. Similarly in '1.2 Motivation'. It is stated that 'It is clear that there is a need for a library to manage processes'. If i had no previous knowledge of managing processes it wouldn't be clear from the documentation so far that there is this need. What seems more clear from this section is the authors desire to get their library included in a future C++ standard. Thanks
