* Split help message into brief and full help Demonstrate on ansi command Brief help is printed when running `help commands` so it doesn't clutter the table. Full help is printed when normal help message is requested (e.g., `help ansi`, `ansi --help`, etc.). * Split long command descriptions Some are not split, just edited to be shorter. * Capitalize the usage of all commands * Make sure every usage ends with dot * Fix random typo
