In /doc/en/list.xml, we have "Gentoo Network APpliance User Guide". I think "Appliance" is better than "APpliance", but feel free to mark this bug invalid if you like.
I think this is because the acronym for this is GNAP, and the "AP" belongs to last two letters of the acronym. Imho, would be a bit clearer if we use: "Gentoo Network Appliance User Guide (GNAP)" because most users mainly know the acronym and it would be succesfull to perform a search using "GNAP". BTW, this doc is out of scope of GDP, since it belongs to "/proj/en/base/embedded/". Our list.xml only parses the title of the doc and indexes it. Bug redirected to koon which seems to be the main dev behind GNAP and the author of the doc.
The titles of the GNAP docs have been fixed.
