Hi all!

Is there any interest in a library for configuration file parsing?

I know there is a good library Program_options, but it supports (asit is 
written in the documentation) "parsing of simple INI-like configuration 
files". If all you need for configure your programs is INI-like files - 
use Program_options and forget about this letter. But if you want to use 
a more complex configuration files, you may be interested in my library, 
Configurator.

simplest.conf:
Host = 127.0.0.1

Code for work with this config:
cf::configurator configurator;
configurator.add_option( "Host" );
configurator.parse( "/some/path/to/simplest.conf" );
std::cout << "Value of host: " << configurator.get_value( "Host" )<< 
std::endl;

Features
- Header-only
- Allows to set option's default value or/and necessity.
- Allows to use arbitrary nesting of sections.
- Provides "standard" checks of value's semantic, like correct path, IP 
validity, email correctness, etc.
- Provides "extended" checks of value's semantic, like time period and 
file size.
- Provides common checks of options and sections, like duplication, 
incorrection, etc.
- Supports single-line and multi-line comments (in C++ style).
- Allow to register values with multi-values.
- Allows to set another "name-value" separator (including space symbol), 
instead default '='.
