+ grunt [options] [task [task ...]]
+
+Options
+    --help, -h  Display this help text.
+        --base  Specify an alternate base path. By default, all file paths are
+                relative to the Gruntfile. (grunt.file.setBase) *
+    --no-color  Disable colored output.
+   --gruntfile  Specify an alternate Gruntfile. By default, grunt looks in the
+                current or parent directories for the nearest Gruntfile.js or
+                Gruntfile.coffee file.
+   --debug, -d  Enable debugging mode for tasks that support it.
+       --stack  Print a stack trace when exiting with a warning or fatal error.
+   --force, -f  A way to force your way past warnings. Want a suggestion? Don't
+                use this option, fix your code.
+       --tasks  Additional directory paths to scan for task and "extra" files.

+    --no-write  Disable writing files (dry run).
+ --verbose, -v  Verbose mode. A lot more information output.
+ --version, -V  Print the grunt version. Combine with --verbose for more info.
+  --completion  Output shell auto-completion rules. See the grunt-cli
+                documentation for more information.

+plugins specified in the Gruntfile or via command-line options.
