zathura - pdf viewer
zathura - a document viewer
--------------------
zathura is a pdf viewer based on the poppler pdf rendering library
zathura is a highly customizable and functional document viewer based on the
girara user interface library and several document libraries.
Requirements

and that the Makefile is only compatible with GNU make.
Please note that you need to have a working pkg-config installation and that the
Makefile is only compatible with GNU make. If you don't have a working
pkg-config installation please set the GTK_INC, GTK_LIB, GIRARA_INC, GIRARA_LIB,
SQLITE_INC and SQLITE_LIB variables accordingly.
And also note that rst2man from python-docutils is needed to build
zathurarc.5. If it is not installed, zathurarc.5 won't be built.
Configuration
-------------
You can modify some parts of zathura by editing the config.h file
And also note that rst2man from python-docutils is needed to build zathurarc.5.
If it is not installed, zathurarc.5 won't be built.
Installation
------------
