A long overdue rewrite of my Autoconf tutorial

In 2003, I learned Autoconf in order to write a configure script for libCVD. There were not many good resources for those getting started so I wrote a tutorial.  The tutorial was rather dated and contained some bad practices and missed things I should have covered properly. I also made the mistake of documenting just Autoconf on its own without doing a more in depth treatment of how it integrates with Make. In hindsight that was a mistake. Technically Autoconf is entirely independent of Make. In practice you’re almost always going to use them as a pair and without showing them together it’s hard to convey how to get Autoconf to control Make properly.

I also didn’t have any complete, working examples. Now I have 13.

The new version is now hosted on github:
