/proj/en/releng/catalyst/faq.xml was recently translated. This has not been updated in document status page at http://dev.gentoo.org/~yoswink/doc/es/status/index.html (It still shows "No disponible") Besides, there is no entry for: /proj/en/releng/catalyst/index.xml Cheers!
This page is home-made but generated from the overview.xml official page. I've updated overview so changes will be ready in the project page very soon. Thanks.
