This module is for reading record-oriented data in a delimited text
file. The most common example have records separated by newlines and
fields separated by commas or tabs, but this module aims to provide a
consistent interface for handling sequential records in a file however
they may be delimited. Typically this data lists the fields in the
first line of the file, in which case you should call bind_header to
bind the field name (or not, and it will be called implicitly). If the
first line contains data, you can still bind your own field names via
bind_fields. Either way, you can then use many methods to get at the
data as arrays or hashes.
