+I've made it simple to use, while not forgoing the document's beauty or the
+speed of input.  The logbook, with slight commenting out and editing, could be
+used as a journal by anybody, although the template and graphing functionality
+are set up for people using insulin injections and blood glucose teststrips,
+as well as counting/estimating carbs, protein, and fat.")
