[sqlite] pragma table_info(...) documentation?

[Dan Baker]

I'm needing to find some information about a table, and the table_info 
pragma seems to be the right ticket.

I've looked around, and failed, to find any documentation on this cool 
pragma.
It appears to return 6 columns of data per table-column.  I believe they are 
as follows:
[1] = column# (0...)
[2] = column name
[3] = column affinity/type
[4] = ?
[5] = ?
[6] = ?
Can someone point me to a good place about what is coming back?

Thanks
