    Usage: felis-stack <verb> [<args>]

    The verbs are:

        h, help       Dispalys help
        w, watch      Watches for changes and compiles. Arguments:
					       <Dir>
					       <SassDir> <BabelDir> <HtmlDir>
					       <SassDir> <CssOutDir> <BabelDir> <JsOutDir> <HtmlDir>
		c, compile    Compiles, doesn't listen.
					       <Dir>
					       <SassDir> <BabelDir> <HtmlDir>
					       <SassDir> <CssOutDir> <BabelDir> <JsOutDir> <HtmlDir>

	The args are:

		--debug <level>
				Prints debug information while code is running. Level (0 - 2)
				indicates how much debug info to print. 0(default) is least, 2 is most
		--ignore [dir, dir, ...]
				Ignores certian dirs
		--check <n>
				Checks for new files every n seconds.
				0 = don't check
				Default = 0
		--compileOnRun

		".babl" files are compressed
		".scss" files are compressed
