@Skif-off the part that possibly is affected is the `Adding a TagManager parser` section, but its very general and looks like its written for those who already know what they are doing (which is not me as far as adding ctags parsers, so I may be wrong).
Since its so general I don't think its affected by any changes to the ctags layout. What it might possibly need is an improvement, but thats something to make a separate issue/pull request.
