    cli: introduce a help command Add a framework for commands to be defined, and add our first one, "help". When `git2_cli help` is run, the `cmd_help` function will be invoked with the remaining command line arguments. This allows users to invoke `git2_cli help foo` to get information about the `foo` subcommand.

  • cli

    A git-compatible command-line interface that uses libgit2.

    Adding commands

    1. Individual commands have a main-like top-level entrypoint. For example: 

      int cmd_help(int argc, char **argv)

      Although this is the same signature as main, commands are not built as individual standalone executables, they’ll be linked into the main cli. (Though there may be an option for command executables to be built as standalone executables in the future.)

    2. Commands are prototyped in cmd.h and added to main.c‘s list of commands (cli_cmds[]). Commands should be specified with their name, entrypoint and a brief description that can be printed in git help. This is done because commands are linked into the main cli.

    3. Commands should accept a --help option that displays their help information. This will be shown when a user runs <command> --help and when a user runs help <command>.
