CSV like file format featured recently in Daily Python URL?

[Alex Willmer]

I'm trying to track down the name of a file format and python module,
that was featured in the Daily Python URL some time in the last month or
two.

The format was ASCII with a multiline header defining types for the
comma seperated column data below. It may have had the capability to
store multiple tables in one file. There was news on the homepage that
an alternate 'no data here' syntax was also supported.

An example file had vaguely this structure:

columnname as datatype
columnname as datatype
columnname as datatype
columnname as datatype

data,data,data,data
data,"other data",data,data
data,data,"",data

Can anyone remember this file format/python module?

With thanks

Alex
