Hi, I would like to request review of property_tree library. It is available for download at http://boost-consulting.com/vault, current filename is property_tree_rev4.zip. Documentation is also available online at http://kaalus.atspace.com/ptree A short description: Property tree is a data structure - a tree of (key, value) pairs. It differs from its cousin, "usual" property map, because it is hierarchical, not linear. Thus, it is more like a minimalistic Document Object Model, but not bound to any specific file format. It can store contents of XML files, windows registry, JSON files, INI files, even command line parameters. The library contains parsers for all these formats, and more. By any chance it is not a substitute for (upcoming?) boost XML library - it only supports a subset of XML, and focuses rather on being format-independent. cheers, Marcin
