elpa-page-break-lines binary package in Ubuntu Mantic amd64

 This library provides an Emacs mode which displays form feed
 characters as horizontal rules.
 .
 The U+000C FORM FEED character is a normal white-space character, and
 in a text file is often used to mark virtual “page” separation.
 .
 Though it is rendered invisibly as white space, Emacs will (like many
 text editors) represent it with a glyph such as “^L”. This Emacs mode
 allows the same character to instead display as a custom horizontal
 line.
