  "Minor mode to automatically generate and update tags tables.

This minor mode generates the tags table automatically based on
the current project configuration, and later updates it as you
edit the files and save the changes.

If you select a tags table manually (for example, using
\\[visit-tags-table]), then this mode will be effectively
disabled for the entire session.  Use \\[tags-reset-tags-tables]
to countermand the effect of a previous \\[visit-tags-table]."
