# Select texchanges-review.tex as the Overleaf Main document to compile the
# automatic comparison. Other Main documents, including
# texchanges-explicit-review.tex, compile normally.
#
# The branch tests %S, the source filename, because that is the same locally and
# on Overleaf. %B is the job name, and Overleaf compiles with -jobname=output,
# so a test against %B matches only on a local run.
#
# -jobname=%B keeps the output named the way the caller expects. Overleaf looks
# for output.pdf and reports "no PDF" if pdflatex writes some other name.
#
# MINWORDSBLOCK=1 preserves short shared phrases such as "system provides".
