    Krop is a tool that allows you to optimise your PDF files, and remove
    sections of the page you do not want.  A unique feature of krop, at least to my
    knowledge, is its ability to automatically split pages into subpages to fit the
    limited screensize of devices such as eReaders. This is particularly useful, if
    your eReader does not support convenient scrolling. Krop also has a command line
    interface.
