usage: ninja [options] [targets...]

if targets are unspecified, builds the 'default' target (see manual).

options:
  --version      print ninja version ("1.13.2")
  -v, --verbose  show all command lines while building
  --quiet        don't show progress status, just command output

  -C DIR   change to DIR before doing anything else
  -f FILE  specify input build file [default=build.ninja]

  -j N     run N jobs in parallel (0 means infinity) [default=66 on this system]
  -k N     keep going until N jobs fail (0 means infinity) [default=1]
  -l N     do not start new jobs if the load average is greater than N
  -n       dry run (don't run commands but act like they succeeded)

  -d MODE  enable debugging (use '-d list' to list modes)
  -t TOOL  run a subtool (use '-t list' to list subtools)
    terminates toplevel options; further flags are passed to the tool
  -w FLAG  adjust warnings (use '-w list' to list warnings)
