Hello! I tried to find info about this topic, without much success...
How can I pick a language for a document not included in the drop-down menu from LyX? I want to typeset a document in a language not included, and I can't figure out how to include it. Please notice that I don't want to ADD a custom language to a preset one: I want to use a language not included in the menu as the only and main language. Thanks in advance, Luis.
