FBPDF
=====

Fbpdf is a framebuffer PDF and DjVu viewer.  There are three make
targets:

* fbpdf: uses mupdf library for rendering PDF, CBZ, and EPUB files.
* fbpdf2: uses poppler library for rendering PDF files.
* fbdjvu: uses djvulibre library for rendering DjVu files.

The default target is fbpdf; to build the other two, they must be
explicitly specified.

The following options are available in all three programs:

  fbpdf [-r rotation] [-z zoom_x10] [-p page_number] file.pdf

The following table lists the commands available in fbpdf.  Most of
them accept a numerical prefix.  For instance, '^F' tells fbpdf to
show the next page while '5^F' tells it to show the fifth next page.
