How to Use: Chapter ZIP file or chapter1 directory on http://hf-mw.com (normal mode)
Everything you need for completing the exercises in the chapter is contained in the chapter1.zip file, which is an archive of the chapter1 directory.
Execute the build.sh script; it will spit out a chapter1 directory and also a ZIP archive of same. This is the starting point for the exercises in the chapter. You can then use chapter1 exclusively and ignore everything else.
