A question from the truly dumb?

[William Case]

Hi,

More and more I have noticed the use of a double colon [::]in coding
explanations but have not noticed it actually used anywhere.  Does it
mean anything other than being used as a format.  

For example, in a recent repo description:

        perl-DateTime-Format-Natural
        Description :
        DateTime::Format::Natural takes a string with a human readable
        date/time and creates a machine readable one by applying natural
        parsing logic.
        
rsync uses the :: in its a man pages.  There it seems to indicate a
remote machine, but doesn't seem to be required.

Just something I have been meaning to ask for a long time.
