Hi, Volodya!

This is example of more complex configuration file:
--------------------------------------------------------------------------------------
/*
  * more_complex.conf
  */

DbName       : my_database
DbHost        : localhost
DbPort         : 100
DbUser         : some_user
DbPassword  : some_password

<Server>
     Host           : 12.45.46.15               // IP semantic may be check.
     Port           :  1080                          // Value must be 
unsigned integer number.
     Admin/*this is comment with unnecessary info
     asf*/istrator  : admin_at_[hidden]             // e-mail semantic 
may be check.

     StorePath     :  /some/path                            // path 
semantic may be check.

<Internal>
         Logfile              : /some/path/to/logfile     // path 
semantic may be check.
         MaxLogFileSize  : 10 MB                           // size 
semantic may be check, result in bytes.
</Internal>

     ReconnectPeriod : 10 m  // time-period semantic may be check, 
result in seconds.
</Server>

I know boost::property_tree, this is very good library, but (imho) it is 
designed specifically to advanced work with XML (though not only with 
him). In other words, primaryarea of this library is notwork with 
configuration files(imho). I could not find in the documentation (or in 
examples) of boost::property_tree features such as option's default 
value or necessary.

My library designed exactly for work with configuration files and not 
for anything more, so it usageis very simple for THIS task.
