Yadex is now installed.

You will need to copy the example yadex.cfg from
${PREFIX}/share/games/yadex/ to either ~/.yadex/
or /etc/yadex/. 

Before you run it, enter the paths to your iwads in
/etc/yadex/yadex.cfg or ~/.yadex/yadex.cfg. When
you're done, type "yadex" to start. If you're
confused, take a look at the full HTML documentation:
${PREFIX}/share/doc/yadex/index.html

Happy editing !
