	Roundcube inline PDF Viewer
	===========================
	The rendering of PDF documents is based on the pdf.js library
	by andreasgal. See http://mozilla.github.com/pdf.js/ for more information.


	INSTALLATION
	------------

	Add 'pdfviewer' to the list of plugins in the config/main.inc.php file
	of your Roundcube installation.


	BUILD (for developers only)
	-----
	Clone the git repository into a local directory:

	$ git clone https://github.com/mozilla/pdf.js.git pdfjs
	$ cd pdfjs

	To actually build the viewer, node.js is required!

	$ node make generic

	The viewer is generated in build/generic/web/ and the pdf.js script in
	build/generic/build/pdf.js. Copy build/generic/web/ to the plugin directory
	<roundcubedir>/plugins/pdfviewer/viewer/ and also copy pdf.js into the viewer
	directory:

	$ cd <roundcubedir>/plugins/pdfviewer
	$ cp -r <pdfjsdir>/build/generic/web viewer
	$ cp <pdfjsdir>/build/generic/build/pdf.js viewer/pdf.js
	$ rm viewer/*.pdf

	Then apply the pdfjs-viewer.diff patch to adjust the viewer for the use
	within Roundcube:

	$ patch -p1 < pdfjs-viewer.diff

	Optionally, compress the scripts using Google's Closure Compiler [1]
	or the YUI Compressor [2].

	$ <roundcubedir>/bin/jsshrink.sh viewer/pdf.js ECMASCRIPT5
	$ <roundcubedir>/bin/jsshrink.sh viewer/viewer.js ECMASCRIPT5
