Great, thanks for doing that.

Noticed while quickly looking over the file:

- it is not valid xml: & needs to be escaped as &

- 'gui' is not a great term to use. I'd suggest rewording the first
sentence maybe as 'Yum extender is a graphical package management
application, ...'

- Instead of 'categories' I would say 'criteria' in 'Browse packages
by...'. Categories already has (too many) meanings...
