Sometimes we need data split into records and a simple split on the input record separator ($/) or some other value fails because the values we're splitting on may allowed in other parts of the data. Perhaps they're quoted. Perhaps they're embedded in other data which should not be split up. This module allows you to specify what you wish to split the data on, but also speficy an "unless" regular expression. If the text in question matches the "unless" regex, it will not be split there. This allows us to do things like split on newlines unless newlines are embedded in quotes.
