This is not an official snap.
Dosage is designed to keep a local copy of specific webcomics and other
picture-based content such as Picture of the Day sites. With the dosage
command line script you can get the latest strip of a webcomic, or catch-up
to the last strip downloaded, or download a strip for a particular
date/index (if the webcomic's site layout allows this).
For advanced options and features execute `dosage --help`.
