Product Features Format for CSV files

[puckstop]

A quick question on the csv upload for products. I see where the Prestashop format for csv import allows for upload of feature information as well. The format is Feature(Name:Value:Position). How are multiple features separated? For example, a particular product has the following features:

 

Caliber  9mm

Action Type        DA/SA (SRT) or DAK

Trigger Pull DA   10.0 lbs or 5.5-6.5 lb (DAK)

Trigger Pull SA   4.4 lbs

Overall Length   6.7 in

Overall Height   4.5 in

Overall Width    1.3 in

Barrel Length     3.5 in

Sight Radius        5.3 in

 

How would I go about adding these to the csv file so they load with the product info? Thanks for any help you can provide.
