it should be possible to use any container for Arguments as long as its  
elements are std::strings. The flexibility regarding Context is more  
theoretical (you basically have to copy boost::process::context and can't  
leave anything out).

In early versions of the library one of the goals was to support multiple  
string types. In practice nothing but std::string ever worked. There were  
once also multiple context classes when the library shipped  
platform-specific classes for POSIX and Windows. As of today  
create_child() heavily depends on boost::process::context though.

HTH,
