# 1. Sometimes a run with errors results from or has produced
# a bad .aux file. This gets read in on the next run and
# an infinite error loop results unless the .aux file is
# deleted or replaced by something innocuous.
# 2. Latexmk is liable to make extra runs of latex after an
# error is produced. In simple cases, this can be avoided
# if the aux file is later than the tex file and the
# aux.bak file has the same contents.
