+** Project.el
+An inbuilt solution for creating and managing projects that doesn't
+require a dependency.  Where possible we should try to use Emacs
+defaults (admittedly this is a philosophy I've only recently adopted)
+so when setting up a new computer it takes a bit less time.
+
+Here I write a TAGS command, mimicking projectile's one, so I can
+quickly generate them in C/C++ projects.
