+### Build and deploy a presentation

+### and Matthew Brett (https://github.com/matthew-brett/thw-intro/blob/master/Makefile)
+### If you want to use this file as-is, then you
+### need to change the variables below to your
+### own SSH user, document root, etc.
+### 
+### However, you will most likely also want to
+### customize the various steps (e.g. the css target)
+### so that it matches the details of your own
+### setup.
+### 
+### Apart from hugo, you will also need rsync to deploy
+### the site, and the java-based yuicompressor to
+### minify the CSS, should you keep that step.
