POKI_PUT_TOC_HERE

File-format awareness

Miller respects CSV headers. If you do mlr --csv cat *.csv then the header line is written once:
POKI_RUN_COMMAND{{cat data/a.csv}}HERE POKI_RUN_COMMAND{{cat data/b.csv}}HERE POKI_RUN_COMMAND{{mlr --csv cat data/a.csv data/b.csv}}HERE POKI_RUN_COMMAND{{mlr --csv sort -nr b data/a.csv data/b.csv}}HERE
Likewise with mlr sort, mlr tac, and so on.
