+        - Powerful enough to support all common uses.
+        - Simple and easy to learn/use.
+        - Minimal code size and external dependencies.
+        - Extensible for custom syntaxes.
+
+        First all options are registered. After that, elements of command line
+        are extracted using operator++. 
+
+        For each element, user can find
+        - if it's an option or an argument
+        - name of the option
+        - index of the option
+        - option value(s), if any
+        
+        Sometimes the registered option name is not equal to the encountered
+        one, for example, because name abbreviation is supported.  Therefore
+        two option names can be obtained: 
+        - the registered one 
+        - the one found at the command line
+
+        There are lot of style options, which can be used to tune the command
+        line parsing. In addition, it's possible to install additional parser
+        which will process custom option styles.
+
+        @todo mininal match length for guessing?

+    /** Standalone parser for config files in ini-line format.
+        The parser is a model of single-pass lvalue iterator, and
+        default constructor creates past-the-end-iterator. The typical usage is:
+        config_file_iterator i(is, ... set of options ...), e;
+        for(; i !=e; ++i) {
+            *i;
+        }
+        
+        Syntax conventions:
+
+        - config file can not contain positional options
+        - '#' is comment character: it is ignored together with
+          the rest of the line.
+        - variable assignments are in the form
+          name '=' value.
+          spaces around '=' are trimmed.
+        - Section names are given in brackets. 
+
+         The actual option name is constructed by combining current section
+         name and specified option name, with dot between. If section_name 
+         already contains dot at the end, new dot is not inserted. For example:
+         @verbatim
+         [gui.accessibility]
+         visual_bell=yes
+         @endverbatim
+         will result in option "gui.accessibility.visual_bell" with value
