  	/// This implementation of a Configuration reads properties
  	/// from a legacy Windows initialization (.ini) file.
  	///
  	/// The file syntax is implemented as follows.
  	///   - a line starting with a semicolon is treated as a comment and ignored
  	///   - a line starting with a square bracket denotes a section key [<key>]
  	///   - every other line denotes a property assignment in the form
  	///     <value key> = <value>
  	///
  	/// The name of a property is composed of the section key and the value key,
  	/// separated by a period (<section key>.<value key>).
  	///
  	/// Property names are not case sensitive. Leading and trailing whitespace is
  	/// removed from both keys and values.
