visit-tags-table

,----
| visit-tags-table is an interactive autoloaded Lisp function in
| `etags.el'.
| 
| It is bound to <menu-bar> <edit> <goto> <set-tags-name>.
| 
| (visit-tags-table file &optional local)
| 
| Tell tags commands to use tags table file file.
| file should be the name of a file created with the `etags' program.
| A directory name is ok too; it means file TAGS in that directory.
| 
| Normally M-x visit-tags-table sets the global value of `tags-file-name'.
| With a prefix arg, set the buffer-local value instead.
| When you find a tag with M-., the buffer it finds the tag
| in is given a local value of this variable which is the name of the tags
| file the tag was in.
