Except for one problem. If the second run of "bcp" selects less files than
the first, and you only ovewrite files, not clean up the entire directory,
the number of files will not be reduced. Uncessasary ones will just lay in
the directory.

I start to understand why Gennadiy Rozental was saying that dependency from
program_options to function is a bit too much --- don't feel all that good
about adding 2Megs just for command line parsing. Of course, this only
matters when packaging library separately.
