Convert Rust books to EPUB (incl. The Rust Programming Language)

The following steps work for all the HTML learning materials on the Learn Rust page:

Click on the "Print this book" icon in the top right corner.
"Cancel" print popup.
Press F12.
Copy, paste, and run the contents of ebookFormatPreparation.js into your browser's console.
Save the modified HTML file.

Before you begin

Make sure you have adb installed and that it works. Test this by connecting your phone and running adb devices. In order to proceed past the build stage, your device must be rooted. The device I used is running Cyanogenmod with root enabled for both apps and adb.

Build

Fetch the Android NDK

You'll need to get the Android NDK. I used r8e, which you can get from here: http://dl.google.com/android/ndk/android-ndk-r8e-linux-x86.tar.bz2. Make sure you get the x86 version, as the x86_64 version will not help you. Let's call the path where you unpack this NDK_PATH.

	double computeDewPoint2(double celsius, double humidity)
	{
	double RATIO = 373.15 / (273.15 + celsius); // RATIO was originally named A0, possibly confusing in Arduino context
	double SUM = -7.90298 * (RATIO - 1);
	SUM += 5.02808 * log10(RATIO);
	SUM += -1.3816e-7 * (pow(10, (11.344 * (1 - 1/RATIO ))) - 1) ;
	SUM += 8.1328e-3 * (pow(10, (-3.49149 * (RATIO - 1))) - 1) ;
	SUM += log10(1013.246);
	double VP = pow(10, SUM - 3) * humidity;

	var path = require('path');

	var _invalidateRequireCacheForFile = function(filePath){
	delete require.cache[path.resolve(filePath)];
	};

	var requireNoCache = function(filePath){
	_invalidateRequireCacheForFile(filePath);
	return require(filePath);
	};

	var svg = document.querySelector( "svg" );
	var svgData = new XMLSerializer().serializeToString( svg );

	var canvas = document.createElement( "canvas" );
	var ctx = canvas.getContext( "2d" );

	var img = document.createElement( "img" );
	img.setAttribute( "src", "data:image/svg+xml;base64," + btoa( svgData ) );

	img.onload = function() {
