$ run-s [--help | -h | --version | -v]
$ run-s [OPTIONS] <tasks>
Run given npm-scripts sequentially.
<tasks> : A list of npm-scripts' names and Glob-like patterns.
Options:
-c, --continue-on-error - Set the flag to continue executing subsequent

itself will exit with non-zero code if one or
more tasks threw error(s).
--npm-path <string> - - - Set the path to npm. Default is the value of
environment variable npm_execpath.
If the variable is not defined, then it's "npm."
In this case, the "npm" command must be found in
environment variable PATH.
-l, --print-label - - - - Set the flag to print the task name as a prefix
on each line of output. Tools in tasks may stop
coloring their output if this option was given.
-n, --print-name - - - - Set the flag to print the task name before
running each task.
-s, --silent - - - - - - Set 'silent' to the log level of npm.
Shorthand aliases can be combined.
For example, '-clns' equals to '-c -l -n -s'.

$ run-s build:**
$ run-s lint clean build:**
$ run-s --silent --print-name lint clean build:**
$ run-s -sn lint clean build:**
