When I run "luajit -b" without arguments LuaJIT shows me a usage for "-b":
[0] ~/sources/MRG/tarantool/third_party/luajit$ ./build/src/luajit -b
Save LuaJIT bytecode: luajit -b[options] input output
-l Only list bytecode.
-s Strip debug info (default).
-g Keep debug info.
-n name Set module name (default: auto-detect from input name).
-t type Set output file type (default: auto-detect from output name).
-a arch Override architecture for object files (default: native).
-o os Override OS for object files (default: native).
-e chunk Use chunk string as input.
-- Stop handling options.
- Use stdin as input and/or stdout as output.
File types: c h obj o raw (default)
When I run "luajit -t" without arguments LuaJIT shows me the same usage,
that is not helpful:
[0] ~/sources/MRG/tarantool/third_party/luajit$ ./build/src/luajit -t
usage: ./build/src/luajit [options]... [script [args]...].
Available options are:
-e chunk Execute string 'chunk'.
-l name Require library 'name'.
-b ... Save or list bytecode.
-j cmd Perform LuaJIT control command.
-O[opt] Control LuaJIT optimizations.
-i Enter interactive mode after executing 'script'.
-v Show version information.
-t<cmd> Execute tool.
-E Ignore environment variables.
-- Stop handling options.
- Execute stdin and stop handling options.
Please show a usage with available arguments for "-t":
Parse profile dump: luajit -t[options] input
-m parse memprof dump.
-s parse sysprof dump (default).
--leak-only ...
--split ...

Let's define this global in .luacheckrc.
I think we will use _TARANTOOL more and this inline suppressions will be
annoying.
