Usage: vnews 

When you run Vnews for the first time, a .vnewsrc configuration file will be
generated in your home directory.  You must edit this file to match your MySQL
settings, and then run `vnews --create-db`.

After that you can run `vnews` to read your feeds.

Specific options:

-u, --update           Update all feeds and folders before starting vnews
-U                     Update all feeds and folders without starting vnews session
--opml [opml file]     Import feeds from an OPML file
--create-db            Create MySQL database configured in .vnewrc 
-v, --version          Show version
-h, --help             Show this message
