+KindlePDFViewer
+===============
+
+This is a PDF viewer application, created for usage on the Kindle e-ink reader.
+It is currently restricted to 4bpp inverse grayscale displays. It's using the
+muPDF library (see http://mupdf.com/) and its UI is scripted using Lua (see
+http://www.lua.org/).
+
+The application is licensed under the GPLv3 (see COPYING file).
+
+
+Building
+========
+
+
+Follow these steps:
+
+* fetch thirdparty sources
+	* manually fetch all the thirdparty sources:
+		* install muPDF sources into subfolder "mupdf"
+		* install muPDF third-party sources (see muPDF homepage) into a new
+		subfolder "mupdf/thirdparty"
+		* install libDjvuLibre sources into subfolder "djvulibre"
+		* install CREngine sources into subfolder "kpvcrlib/crengine"
+		* install LuaJit sources into subfolder "luajit-2.0"
+
+	* automatically fetch thirdparty sources with Makefile:
+		* make sure you have wget, unzip and git installed
+		* run "make fetchthirdparty".
+
+* adapt Makefile to your needs
+
+* run `make thirdparty`. This will build MuPDF (plus the libraries it depends
+  on), libDjvuLibre, CREngine and Lua.
+
+* run `make`. This will build the kpdfview application
+
+
+Running
+=======
+
+The user interface (or what's there yet) is scripted in Lua. See "reader.lua".
+It uses the Linux feature to run scripts by using a corresponding line at its
+start.
+
+So you might just call that script. Note that the script and the kpdfview
+binary currently must be in the same directory.
+
+You would then just call reader.lua, giving the document file path, or any
+directory path, as its first argument. Run reader.lua without arguments to see
+usage notes.  The reader.lua script can also show a file chooser: it will do
+this when you call it with a directory (instead of a file) as first argument.
+
+
+Device emulation
+================
+
+The code also features a device emulation. You need SDL headers and library
+for this. It allows to develop on a standard PC and saves precious development
+time. It might also compose the most unfriendly desktop PDF reader, depending
+on your view. 
+
+If you are using Ubuntu, simply install `libsdl-dev1.2` package.
+
+To build in "emulation mode", you need to run make like this:
+	make clean cleanthirdparty
+	EMULATE_READER=1 make thirdparty kpdfview
+
+And run the emulator like this:
+```
+	./reader.lua /PATH/TO/PDF.pdf
+```
+or:
+```
+	./reader.lua /ANY/PATH
+```
+
+By default emulation will provide DXG resolution of 824*1200. It can be
+specified at compile time, this is example for Kindle 3:
+
+```
+	EMULATE_READER_W=600 EMULATE_READER_H=800 EMULATE_READER=1 make kpdfview
+```
+
