0006 * I recall finding that the main level must larger than the libs
0007   for all the expected libs output to appear
0008   ie that both level criteria gets applied
0009
0010   * TODO: confirm this, and see if some other organization might avoid that
0011
0012 * https://github.com/SergiusTheBest/plog/issues/72

0016     Also you can rewrite your previous sample:
0017
0018     plog::init<1000>(plog::verbose, "/var/log/my.log");
0019     plog::init<0>(plog::info, plog::get<1000>());
0020     plog::init<1>(plog::debug, plog::get<1000>());
0021     plog::init<2>(plog::warning, plog::get<1000>());
0022
0023     so the default log stays 0 and the sink becomes 1000.
