Done.

+ // the list with a qvalue appended to each language. |
+ // The way qvalues are assigned is rather simple. The qvalue |
+ // starts with 1.0 and is decremented by 0.2 for each successive entry |
+ // in the list until it reaches 0.2. All the entries after that are |
+ // assigned the same qvalue of 0.2. Also, note that the 1st language |
+ // will not have a qvalue added because the absence of a qvalue implicitly |
+ // means q=1.0. |
+ // |
+ // When making a http request, this should be used to determine what |
+ // to put in Accept-Language header. If a comma separated list of language |
+ // codes *without* qvalue is sent, web servers regard all |
+ // of them as having q=1.0 and pick one of them even though it may not |
+ // be at the beginning of the list (see http://crbug.com/5899). |
