# (Public domain. Originally written by Karl Berry, 2010.)
# This is just about creating the derived bst files, checking for
# changes, making the distribution for CTAN, etc. It does not actually
# build a BibTeX executable. So we keep it in the source repository.
# We're using the TL repo (source/extra/bibtex) purely for convenience.

# -w since we know that we have unterminated ', ec.
# -P since we don't want #line in the output.
# -DBSTNAME taken from the target.

# Then we grep away the comments without leading whitespace,
