 # This is a compilation handler, so to speak, which I have vim run.
 #
 # It compiles a document to pdf
+#
+# If you put the sequence `xelatex` somewhere in the first 5 lines of a .tex
+# file, it will be compiled with `xelatex` rather than `pdflatex`.
+#
+# If it detects an `addbibresource` line, it will run `biber` and perform
+# multiple compiles to get the references correct.
