+## Development
+
+While the build process itself does not require it, development uses Ruby for
+integration testing because of the excellent Cucumber/Aruba package for testing
+CLI tools.
+
+Thus, to bootstrap, you will need to have Ruby and bundler installed on your
+system.  Do `bundle install` to get the dev environment going.
+
+Since we already have Ruby then for tests, we use a Rakefile instead of Makefile
+since it offers some niceties.  Do `rake -T` to see available tasks.

+By default, scmpuff will attempt to utilize the absolute path of whatever `git`
