Add command line flags to link to information This patch provides command line flags `--help` and `--license` as well as the corresponding `help` and `license` commands. ``` $ ./stockfish --help Stockfish 200522 by the Stockfish developers (see AUTHORS file) Stockfish is a powerful chess engine and free software licensed under the GNU GPLv3. Stockfish is normally used with a separate graphical user interface (GUI). Stockfish implements the universal chess interface (UCI) to exchange information. For further information see https://github.com/official-stockfish/Stockfish#readme or the corresponding README.md and Copying.txt files distributed with this program. ``` The idea is to provide a minimal help that links to the README.md file, not replicating information that is already available elsewhere. We use this opportunity to explicitly report the license as well. closes https://github.com/official-stockfish/Stockfish/pull/4027 No functional change.
