A.6 Boot Template

Although running the command org-babel-tangle (‘C-c C-v t’) from within Emacs will install everything, it would be nice to have a simple Makefile that is downloaded with this file that could be invoked to do the same thing without starting Emacs and Org-mode and keying in the org-babel-tangle command. This little Makefile should be stored on GitHub along with the Template.org file. When the source is extracted to a directory, then running this Makefile’s default rule as simply make will extract the preprocess.el script, which updates ‘DEV’ and then extracts the full Makefile. Because this file is tangled along with the full Makefile, it simply gets tacked onto the end of the big Makefile as an additional rule. Now, running make runs the default rule from the main Makefile, which is to extract everything, then export to TEXI, INFO, HTML, and PDF forms.

It is assumed that an Emacs server is running, and that the $EDITOR environment variable is set to use emacsclient.
