-usage: public-inbox-extindex [options] EXTINDEX_DIR [INBOX_DIR]
+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)
BYTES may use `k', `m', and `g' suffixes (e.g. `10m' for 10 megabytes)
See public-inbox-extindex(1) man page for full documentation.
