All packages available in the XMLEye private repository are signed with my GPG key. You'll have to add it to your apt keyring, as usual. You can either download it manually and add it under the Authentication tab from the “Software sources” administration tool, or use this command:

wget http://www.shoyusauce.org/packages/claveDebian.asc -O- | sudo apt-key add -

You must add these two lines to your /etc/apt/sources.list:

deb http://www.shoyusauce.org/packages/ubuntu gutsy main
deb-src http://www.shoyusauce.org/packages/ubuntu gutsy main

You can do it manually or use the “Software sources” administration tool, as in the previous step. If you use Synaptic, you will have to tell it to update the package listings.

You only have to update and install XMLEye and some converters, like this:

sudo aptitude update
sudo aptitude install xmleye libacl2-procesador-perl libyaxml-reverse-perl

All dependencies will also be installed as needed. If you're using Synaptic, you can just take the names of the above packages (the names right after the install keyword).

Your preferences will be saved in ~/.xmleye, stylesheets will be available at /usr/share/xmleye/xslt, and document format descriptors will be at /usr/share/xmleye/types.
