vim-gutentags - A Vim plugin that manages your tag files
Gutentags is a plugin that takes care of the much needed management of tags files in Vim. It will (re)generate tag files as you work while staying completely out of your way. It will even do its best to keep those tag files out of your way too. It has no dependencies and just works. Then you only need to do a :call pathogen#helptags() to generate the documentation tags (how ironic, eh?) and you can access Gutentags' help pages with help gutentags.
