Hi/re

But what if i don't want to use dedicated variables, and want to store all
configuration in one place?  For example, i need to load configuration from
file, but set some variables from the command-line, that will override values
from file. Option processing will done in dedicated thread, and i want to pass
only one argument - program_options object
