+ -- Method on Config: void setOptions (int OPTIONS)
+ -- Method on Config: int getOptions ()
+
+     These methods set and get the options for the configuration.  The
+     options affect how configurations are read and written.  The
+     following options are defined:
+
+     'OptionAutoConvert'
+          Turning this option on enables number auto-conversion for the
+          configuration.  When this feature is enabled, an attempt to
+          retrieve a floating point setting's value into an integer (or
+          vice versa), or store an integer to a floating point setting's
+          value (or vice versa) will cause the library to silently
+          perform the necessary conversion (possibly leading to loss of
+          data), rather than reporting failure.  By default this option
+          is turned off.
+
+     'OptionSemicolonSeparators'
+          This option controls whether a semicolon (';') is output after
+          each setting when the configuration is written to a file or
+          stream.  (The semicolon separators are optional in the
+          configuration syntax.)  By default this option is turned on.
+
+     'OptionColonAssignmentForGroups'
+          This option controls whether a colon (':') is output between
+          each group setting's name and its value when the configuration
+          is written to a file or stream.  If the option is turned off,
+          an equals sign ('=') is output instead.  (These tokens are
+          interchangeable in the configuration syntax.)  By default this
+          option is turned on.
+
+     'OptionColonAssignmentForNonGroups'
+          This option controls whether a colon (':') is output between
+          each non-group setting's name and its value when the
+          configuration is written to a file or stream.  If the option
+          is turned off, an equals sign ('=') is output instead.  (These
+          tokens are interchangeable in the configuration syntax.)  By
+          default this option is turned off.
+
+     'OptionOpenBraceOnSeparateLine'
+          This option controls whether an open brace ('{') will be
+          written on its own line when the configuration is written to a
+          file or stream.  If the option is turned off, the brace will
+          be written at the end of the previous line.  By default this
+          option is turned on.
 
  -- Method on Config: void setAutoConvert (bool FLAG)
  -- Method on Config: bool getAutoConvert ()
-     `setAutoConvert()' enables number auto-conversion for the
-     configuration if FLAG is `true', and disables it otherwise. When
-     this feature is enabled, an attempt to assign a floating point
-     setting to an integer (or vice versa), or assign an integer to a
-     floating point setting (or vice versa) will cause the library to
-     silently perform the necessary conversion (possibly leading to
-     loss of data), rather than throwing a `SettingTypeException'. By
-     default this feature is disabled.
-
-     `getAutoConvert()' returns `true' if number auto-conversion is
-     currently enabled for the configuration; otherwise it returns
-     `false'.
 
+     These methods get and set the 'OptionAutoConvert' option.  They are
+     obsoleted by the 'setOptions()' and 'getOptions()' methods
+     described above.

  -- Method on Config: Setting::Format getDefaultFormat ()
-     These methods set and get the default external format for settings
-     in the configuration. If a non-default format has not been set for
