widow and orphan control

[Darrin Thompson]

Is there a latex or lyx package of some kind that adds widow and orphan
control?

Just in case I am not using standard words:

widow: The last line of a paragraph containing seven or less characters.

orphan: The last line of paragraph appearing as the first line in a
column.

These are considered undesireable in some cases and I would like to know
if there is any latex or lyx way of automatically removing them.
