 You can also use --ndk-dir=<path> to specify an alternative NDK installation

 The script tries to find the most recent version of the debug version of
 shared libraries under one of the following directories:
 
   \$CHROMIUM_SRC/<out>/lib/                (used by GYP builds)
   \$CHROMIUM_SRC/<out>/lib.unstripped/     (used by GN builds)
 
 Where <out> is 'out' is determined by CHROMIUM_OUT_DIR, CHROMIUM_OUTPUT_DIR, or
-the --out-dir, --output-dir flags.
+the --out-dir, --output-directory flags.
 
 You can restrict this search by using --release or --debug to specify the
 build type, or simply use --symbol-dir=<path> to specify the file manually.
 
 The script tries to extract the target architecture from your target device,
 but if this fails, will default to 'arm'. Use --target-arch=<name> to force
 its value.
 
 Otherwise, the script will complain, but you can use the --gdbserver,
 --gdb and --symbol-lib options to specify everything manually.
