cclog.trace(obj)

stderr if obj is Error instance then log the stack, else inspect it.

cclog.intercept([msg], [callback])

db.get('foo', cclog.intercept('callback foo', handle));

alias

db.get('foo', function(err, data) {
  if(err) {
    cclog.error('callback foo', err);
  } else {
    cclog.info('callback foo', err, data);
  }
  handle && handle(err, data);
}

cclog.ifError

deprecated use cclog.intercept() instead. stderr generate a function to handle error.

fs.mkdir('/foo', function(err) {
  if(err) cclog.error(err);
});

use cclog.ifError to get a closure, NOTE always use cclog.

// WRONG
var ifError = cclog.ifError;
fs.mkdir('/foo', ifError);

// right
fs.mkdir('/foo', cclog.ifError);

cclog.replace()

replace console functions with cclog, console.log(msg) will work like cclog.log(msg)

cclog.restore()

restore original console functions, but keep the function that doesn't present in original console.
