=============================================================================== Convention

Module to wrap/unwrap functions in the node (err, results) convention.

var c = require('convention')

c.wrap(errorHandler, successHandler)

takes two functions, one to handle errors, the other results, and returns them combined.

c.unwrap(nodeFn)

Takes a node style function, and returns an object with an e property for the errorHandler and an s property for the successHandler.
