The directories here that begin with numerals represent subsequent steps as the learner moves through the chapter exercises.
How to Use: Chapter ZIP file or chapter2 directory on http://hf-mw.com (normal mode)
Everything you need for completing the exercises in the chapter is contained in the chapter2.zip file, which is an archive of the chapter2 directory.
Execute the build.sh script; it will spit out a chapter2 directory and also a ZIP archive of same. This is the starting point for the exercises in the chapter. You can then use chapter2 exclusively and ignore everything else.
