File format
The Smile CDR import format is a Comma Separated Values (CSV) file containing three record types:
Commas separating unused columns at the end of a line may not be omitted.
Refer to RFC 4180 (http://www.ietf.org/rfc/rfc4180.txt) for a detailed definition of CSV file formats. Note that Smile will accept a broader definition than this file. For example, any popular newline format (CR/LF) is accepted.
