Highly flexible CSV parser for large files

Surely the CPAN doesn’t need yet another CSV parsing module.

TextCSV_XS is the standard parser for CSV files. It is fast as hell, but unfortunately it can be a bit verbose to use.

A number of other modules have attempted to put usability wrappers around this venerable module, but they have all focussed on parsing the entire file into memory at once.

This method is fine unless your CSV files start to get large. Once that happens, the only existing option is to fall back on the relatively slow and heavyweight XMLSAXDriverCSV module.

ParseCSV fills this functionality gap. It provides a flexible and light-weight streaming parser for large, extremely large, or arbitrarily large CSV files.
