Revision a35349793713aa02055971ed0154ed8da93fac49 authored by Roman Donchenko on 19 April 2023, 08:40:50 UTC, committed by GitHub on 19 April 2023, 08:40:50 UTC
The policy that mandated this is no longer relevant now that CVAT is no longer developed by Intel. Moreover, the source code included was not even complete (it didn't contain Python or NPM packages). This saves ~1.6 GB in the unpacked image (and probably a bunch of build time too, but I didn't measure it).

Usage:
$cmdname host:port [-s] [-t timeout] [-- command args]
-h HOST | --host=HOST Host or IP under test
-p PORT | --port=PORT TCP port under test
Alternatively, you specify the host and port as host:port
-s | --strict Only execute subcommand if the test succeeds
-q | --quiet Don't output any status messages
-t TIMEOUT | --timeout=TIMEOUT
Timeout in seconds, zero for no timeout
-- COMMAND ARGS Execute command with args after the test finishes
USAGE
