% ctags -R
This assumes Exuberant Ctags. The -R (or --recurse) option tells ctags to recurse into directories.
Then, set the tags option in ~/.vimrc as
The last semicolon is the key here. When Vim tries to locate the 'tags' file, it first looks at the current directory, then the parent directory, then the parent of the parent, and so on.
This setting works nicely with 'set autochdir'. You need +path-extra feature for this tip.
You can also tag help/man files, and access it from Vim with commands like these in vimrc:
au FileType perl set tags^=$DOC/perl/tags au FileType cpp set tags^=$DOC/cpp/tags
