# 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.
