  "Minor mode to show the title of a tag in the header line.
Enables/disables making the header line of functions sticky.
A function (or other tag class specified by
`semantic-stickyfunc-sticky-classes') has a header line, meaning the
first line which describes the rest of the construct.  This first
line is what is displayed in the header line.

The minor mode can be turned on only if semantic feature is
available and the current buffer was set up for parsing.  Return
non-nil if the minor mode is enabled."
