Detailed Description

typical use: declare some verbose global object: verbose debug("debug"); verbose stats("stats"); verbose level2("level2");

setup from command line the state of these objects

verbose::setup(command_line_args_to'--verbose=');

cverb << stats << "stats\n"; cverb << (stats&level2) << "very verbose stats\n" cverb << (stats|debug) << "bar\n"; these will give a compile time error cverb << stats << "foo" << debug << "bar"; cout << stats << "foo";

In critical code path cverb can be used in the more efficient way: if (cverb << vdebug) cverb << vdebug << "foo" << "bar"; the condition test the fails bit for the returned stream while the later build a sentry object for each << (more efficient even with one level of <<)
