libcsv is a small, simple and fast CSV library written in pure ANSI
C89 that can read and write CSV[*] data. It provides a straightforward
interface using callback functions to handle fields and rows, and can
parse improperly formatted CSV files.

[*] libcsv is capable of using any delimiter, not just commas.

Included are example utilities:

* csvfix
* csvinfo
* csvvalid
