#   2. make batch IN="/mnt/drive" OUT=docs-output \     # meetus over just the meetings…
#        LIST=docs-output/meetings.txt \                #   …only the listed relative paths
#        OUT_FORMAT="{name}.meetus"                     #   …into <file>.meetus/ sidecars
#   (matches doocus's index pointer, so meetings sit beside the <file>.doocus/ docs.)
