DUNE::Parsers::Config Class Reference

Detailed Description

Microsoft Windows INI configuration file parser.

The configuration file format consists of sections, led by a "[section]" header and followed by "option = value" entries, with continuations in the style of RFC 822. Note that leading and trailing whitespaces are removed from values. Character case in "option" identifiers is discarded. Lines beginning with "#" or ";" are ignored and may be used to provide comments.
