usage: public-inbox-extindex [options] [EXTINDEX_DIR] [INBOX_DIR...]

  Create and update external (detached) search indices

  --no-fsync          speed up indexing, risk corruption on power outage
  --watch             run persistently and watch for inbox updates
  -L LEVEL            `medium', or `full' (default: full)
  --all               index all configured inboxes
  --jobs=NUM          set or disable parallelization (NUM=0)
  --batch-size=BYTES  flush changes to OS after a given number of bytes
  --max-size=BYTES    do not index messages larger than the given size
  --gc                perform garbage collection instead of indexing
  --verbose | -v      increase verbosity (may be repeated)

BYTES may use `k', `m', and `g' suffixes (e.g. `10m' for 10 megabytes)
See public-inbox-extindex(1) man page for full documentation.
