Execute all prepared build tasks.
Usage:
caf [[init] build] work [-v] [--limit N]
[--profile PROFILE [-j N] | [--id ID] [--dry]]
[--last | --queue URL | [TARGET...] [--maxdepth N]]
Options:
-n, --dry Dry run (do not write to disk).
--id ID ID of worker [default: 1].
-p, --profile PROFILE Run worker via ~/.config/caf/worker_PROFILE.
-q, --queue URL Take tasks from web queue.
--last As above, but use the last submitted queue.
-j N Number of launched workers [default: 1].
-l, --limit N Limit number of tasks to N.
-v, --verbose Be more verbose.
--maxdepth N Maximal depth.
