A simple CSV file reader.
READ-CSV(stream &optional (sep #\,) (eof-error-p t) eof-value)Read a single line of CSV data from stream. Return the parsed CSV data and a boolean that is true when you've just read the last record in the stream. eof-error-p controls how this function behaves if the first character read is end-of-file. If true, an error is thrown, if false, the eof-value is returned.
PARSE-CSV(stream &optional (sep #\,))Read CSV data from a stream until end-of-file is encountered.
