This is something that could be part of boost.process which is an SOC project in the works now:

Julio and I have at least discussed that this could either be part or an extension of the core library -- see the bottom of:

If you really want to see this functionality it would be good to say so.

Personally, I think boost should refrain from the bloat that is inevitable from "Hey this library does XYZ, we should have a boost library that does it". I'm happy with the direction boost is going in (if that counts for anything). I look to boost to solve data structure related problems for me where C++ lacks, less so for other things that a full library like POCO can provide. Sohail
