cmdln - npm Package Versions

Pass the subcmd back as the second arg in the <cli>.main callback. This enabled the subcmd to be quoted in an error message if there was an err returned. E.g.:

  var cli = new Mo();
  cli.main(process.argv, function (err, subcmd) {
      if (err) {
          var subcmdStr = subcmd ? ' ' + subcmd : '';    // <---- HERE
          if (err.body && err.body.code) {
              console.error('%s%s: error (%s): %s', cli.name, subcmdStr,
                  err.body.code, err.message);
          } else {
              console.error('%s%s: error: %s', cli.name, subcmdStr,
                  err.message);
          }
          if (cli.opts.verbose && err.stack) {
              console.error('\n' + err.stack);
          }
          process.exit(1);
      } else {
          process.exit(0);
      }
  });

[Backward incompatible change] Underscores in sub-command do_* methods are translated to hyphens for the sub-command name. This means you can have sub-commands with hyphens, at the cost of not allowing underscores.

A sub-command method like this:

  MyCmdln.prototype.do_foo_bar

results in a 'foo-bar' sub-command.

Shout if this breaks you. I could see about making this configurable.

Add cmdln.main for simpler mainline usage, e.g.:

  function MyTool() {
      // ...
  }
  util.inherits(MyTool, cmdln.Cmdln);

  // ...

  if (require.main === module) {
      cmdln.main(MyTool);
  }

Drop support for 'help_FOO' help commands. Not worth the complexity.

Allow custom options given in constructor and a Cmdln.prototype.init hook that is called to handle the top-level options after they are parsed out and before subcmd dispatch. See "examples/conan.js" for an example.

Top-level options are put on this.opts for use by subcmds.

Update to dashdash 1.0.2.
