Multiple countries may be selected using commas (e.g. --country France,Germany) or by passing this option multiple times (e.g. -c fr -c de). Use "--list-countries" to display a table of available countries along with their country codes. When sorting by country, this option may also be used to sort by a preferred order instead of alphabetically. For example, to select mirrors from Sweden, Norway, Denmark and Finland, in that order, use the options "--country se,no,dk,fi --sort country". To set a preferred country sort order without filtering any countries. this option also recognizes the glob pattern "*", which will match any country. For example, to ensure that any mirrors from Sweden are at the top of the list and any mirrors from Denmark are at the bottom, with any other countries in between, use "--country \'se,*,dk\' --sort country". It is however important to note that when "*" is given along with other filter criteria, there is no guarantee that certain countries will be included in the results. For example, with the options "--country \'se,*,dk\' --sort country --latest 10", the latest 10 mirrors may all be from the United States. When the glob pattern is present, it only ensures that if certain countries are included in the results, they will be sorted in the requested order.'
