use_bs_tooltip()

title
character, title for the tooltip
placement
character, placement of the tooltip with respect to tag
...
other named arguments, passed to bs_set_data()

## Details

To activate the use of tooltips in your page, you will need to call the use_bs_tooltip() function somewhere.

The verb embed is used to signify that you are embedding information into a tag. This implies that you can embed, at most, one "thing" into a particular tag. You should not, for example, expect to embed both a tooltip and a popover into a tag.
