 Usage: gulp [options] tasks
 
 Options:
-  --help, -h              Show this help.  [boolean]
-  --version, -v           Print the global and local gulp versions.  [boolean]
-  --require               Will require a module before running the gulpfile. This is useful for transpilers but also has other applications.  [string]
-  --gulpfile, -f          Manually set path of gulpfile. Useful if you have multiple gulpfiles. This will set the CWD to the gulpfile directory as well.  [string]
-  --cwd                   Manually set the CWD. The search for the gulpfile, as well as the relativity of all requires will be from here.  [string]
-  --verify                Will verify plugins referenced in project's package.json against the plugins blacklist.
-  --tasks, -T             Print the task dependency tree for the loaded gulpfile.  [boolean]
-  --tasks-simple          Print a plaintext list of tasks for the loaded gulpfile.  [boolean]
-  --tasks-json            Print the task dependency tree, in JSON format, for the loaded gulpfile.
-  --tasks-depth, --depth  Specify the depth of the task dependency tree.
-  --compact-tasks         Reduce the output of task dependency tree by printing only top tasks and their child tasks.  [boolean]
-  --sort-tasks            Will sort top tasks of task dependency tree.  [boolean]
-  --color                 Will force gulp and gulp plugins to display colors, even when no color support is detected.  [boolean]
-  --no-color              Will force gulp and gulp plugins to not display colors, even when color support is detected.  [boolean]
-  --silent, -S            Suppress all gulp logging.  [boolean]
-  --continue              Continue execution of tasks upon failure.  [boolean]
-  --log-level, -L         Set the loglevel. -L for least verbose and -LLLL for most verbose. -LLL is default.  [count]
