be interesting for other developers.]

Hi Ernest

there is a mechanism for "data" packages, outside the better-known 
"software" section, exactly for cases such as yours. E.g. the 'CCl4' 
package is ~100 MB: 
and 'davidTiling' is afaIr even six times larger.

For several reasons, it is good to separate such a big dataset, and the 
code that uses it, each into their own package - not least because the 
code package can then be updated without re-downloading the data that 
presumably are more stable.

I've just failed to locate the instructions on the website (*) for how 
to submit such a data package - perhaps someone (from Seattle?) can advise?

(*) I looked here:
