Missing are Motivation and Rationale sections. When/Why would someone use this library versus ostream_iterator/Tokenizer/Spirit/...
ostream_iterator does not, AFAIK, handle nested constructs like std::vector< std::list< int > >. Tokenizer is primarliy concerned with reading data back in and I'm not sure if/how it supports containers, arrays and pair/nary types.
Spirit is too complex for when you want simple formatting and is only concerned with parsing (reading) data. It also adds a lot of overhead and does not fit in with the C++ I/O stream framework.
Boost.Serialize does a great job, but is not very flexible in the way that the data is serialized.
You can add this to the docs ;) Best, John -- John Torjo -- john@torjo.com Contributing editor, C/C++ Users Journal -- "Win32 GUI Generics" -- generics & GUI do mix, after all -- http://www.torjo.com/win32gui/ -- v1.4.0 - save_dlg - true binding of your data to UI controls! + easily add validation rules (win32gui/examples/smart_dlg)
