+## SVGO [![npm version](https://img.shields.io/npm/v/svgo)](https://npmjs.org/package/svgo) [![Discord](https://img.shields.io/discord/815166721315831868)](https://discord.gg/z8jX8NYxrE)
+
+**SVG O**ptimizer is a Node.js-based tool for optimizing SVG vector graphics files.
+
+## Why?
+
+SVG files, especially those exported from various editors, usually contain a lot of redundant and useless information. This can include editor metadata, comments, hidden elements, default or non-optimal values and other stuff that can be safely removed or converted without affecting the SVG rendering result.
+
+## Installation
+
+```sh
+npm -g install svgo
+```
+
+or
+
+```sh
+yarn global add svgo
+```
+
+## CLI usage
+
+```sh
+svgo one.svg two.svg -o one.min.svg two.min.svg
+```
+
+Or use the `--folder`/`-f` flag to optimize a whole folder of SVG icons
+
+```sh
+svgo -f ./path/to/folder/with/svg/files -o ./path/to/folder/with/svg/output
+```
+
+See help for advanced usage
+
+```sh
+svgo --help
+```
+
+## Configuration
+
+Some options can be configured with CLI though it may be easier to have the configuration in a separate file.
+SVGO automatically loads configuration from `svgo.config.js` or module specified with `--config` flag.
+
+```js
+module.exports = {
+  multipass: true, // boolean. false by default
+  datauri: 'enc', // 'base64', 'enc' or 'unenc'. 'base64' by default
+  js2svg: {
+    indent: 2, // string with spaces or number of spaces. 4 by default
+    pretty: true, // boolean, false by default
+  },
+};
+```
+
+SVGO has a plugin-based architecture, so almost every optimization is a separate plugin.
+There is a set of [built-in plugins](#built-in-plugins). See how to configure them:
+
+```js
+module.exports = {
+  plugins: [
+    // enable a built-in plugin by name
+    'prefixIds',
+
+    // or by expanded version
+    {
+      name: 'prefixIds',
+    },
+
+    // some plugins allow/require to pass options
+    {
+      name: 'prefixIds',
+      params: {
+        prefix: 'my-prefix',
+      },
+    },
+  ],
+};
+```
+
+The default preset of plugins is fully overridden if the `plugins` field is specified.
+Use `preset-default` plugin to customize plugins options.
+
+```js
+module.exports = {
+  plugins: [
+    {
+      name: 'preset-default',
+      params: {
+        overrides: {
+          // customize options for plugins included in preset
+          inlineStyles: {
+            onlyMatchedOnce: false,
+          },
+
+          // or disable plugins
+          removeDoctype: false,
+        },
+      },
+    },
+
+    // enable builtin plugin not included in default preset
+    'prefixIds',
+
+    // enable and configure builtin plugin not included in preset
+    {
+      name: 'sortAttrs',
+      params: {
+        xmlnsOrder: 'alphabetical',
+      },
+    },
+  ],
+};
+```
+
+Default preset includes the following list of plugins:
+
+- removeDoctype
+- removeXMLProcInst
+- removeComments
+- removeMetadata
+- removeEditorsNSData
+- cleanupAttrs
+- mergeStyles
+- inlineStyles
+- minifyStyles
+- cleanupIDs
+- removeUselessDefs
+- cleanupNumericValues
+- convertColors
+- removeUnknownsAndDefaults
+- removeNonInheritableGroupAttrs
+- removeUselessStrokeAndFill
+- removeViewBox
+- cleanupEnableBackground
+- removeHiddenElems
+- removeEmptyText
+- convertShapeToPath
+- convertEllipseToCircle
+- moveElemsAttrsToGroup
+- moveGroupAttrsToElems
+- collapseGroups
+- convertPathData
+- convertTransform
+- removeEmptyAttrs
+- removeEmptyContainers
+- mergePaths
+- removeUnusedNS
+- sortDefsChildren
+- removeTitle
+- removeDesc
+
+It's also possible to specify a custom plugin:
+
+```js
+const anotherCustomPlugin = require('./another-custom-plugin.js');
+module.exports = {
+  plugins: [
+    {
+      name: 'customPluginName',
+      type: 'perItem', // 'perItem', 'perItemReverse' or 'full'
+      params: {
+        optionName: 'optionValue',
+      },
+      fn: (ast, params, info) => {},
+    },
+    anotherCustomPlugin,
+  ],
+};
+```
+
+## API usage
+
+SVGO provides a few low level utilities.
+
+### optimize
+
+The core of SVGO is `optimize` function.
+
+```js
+const { optimize } = require('svgo');
+const result = optimize(svgString, {
+  // optional but recommended field
+  path: 'path-to.svg',
+  // all config fields are also available here
+  multipass: true,
+});
+const optimizedSvgString = result.data;
+```
+
+### loadConfig
+
+If you write a tool on top of SVGO you might need a way to load SVGO config.
+
+```js
+const { loadConfig } = require('svgo');
+const config = await loadConfig();
+
+// you can also specify a relative or absolute path and customize the current working directory
+const config = await loadConfig(configFile, cwd);
+```

+## [7.2.0] (2021-03-26)
+
+### Added
+
+- TypeScript typing for `parent` property on `Command` ([#1475])
+- TypeScript typing for `.attributeName()` on `Option` ([#1483])
+- support information in package ([#1477])
+
+### Changed
+
+- improvements to error messages, README, and tests
+- update dependencies
+
+## [7.1.0] (2021-02-15)
+
+### Added
+
+- support for named imports from ECMAScript modules ([#1440])
+- add `.cjs` to list of expected script file extensions ([#1449])
+- allow using option choices and variadic together ([#1454])
+
+### Fixed
+
+- replace use of deprecated `process.mainModule` ([#1448])
+- regression for legacy `command('*')` and call when command line includes options ([#1464])
+- regression for `on('command:*', ...)` and call when command line includes unknown options ([#1464])
+- display best error for combination of unknown command and unknown option (i.e. unknown command) ([#1464])
+
+### Changed
+
+- make TypeScript typings tests stricter ([#1453])
+- improvements to README and tests
+
+## [7.0.0] (2021-01-15)
+
+### Added
+
+- `.enablePositionalOptions()` to let program and subcommand reuse same option ([#1427])
+- `.passThroughOptions()` to pass options through to other programs without needing `--` ([#1427])
+- `.allowExcessArguments(false)` to show an error message if there are too many command-arguments on command line for the action handler ([#1409])
+- `.configureOutput()` to modify use of stdout and stderr or customise display of errors ([#1387])
+- use `.addHelpText()` to add text before or after the built-in help, for just current command or also for all subcommands ([#1296])
+- enhance Option class ([#1331])
+  - allow hiding options from help
+  - allow restricting option arguments to a list of choices
+  - allow setting how default value is shown in help
+- `.createOption()` to support subclassing of automatically created options (like `.createCommand()`) ([#1380])
+- refactor the code generating the help into a separate public Help class ([#1365])
+  - support sorting subcommands and options in help
+  - support specifying wrap width (columns)
+  - allow subclassing Help class
+  - allow configuring Help class without subclassing
+
+### Changed
+
+- *Breaking:* options are stored safely by default, not as properties on the command ([#1409])
+    - this especially affects accessing options on program, use `program.opts()`
+    - revert behaviour with `.storeOptionsAsProperties()`
+- *Breaking:* action handlers are passed options and command separately ([#1409])
+- deprecated callback parameter to `.help()` and `.outputHelp()` (removed from README) ([#1296])
+- *Breaking:* errors now displayed using `process.stderr.write()` instead of `console.error()`
+- deprecate `.on('--help')` (removed from README) ([#1296])
+- initialise the command description to empty string (previously undefined) ([#1365])
+- document and annotate deprecated routines ([#1349])
+
+### Fixed
+
+- wrapping bugs in help ([#1365])
+  - first line of command description was wrapping two characters early
+  - pad width calculation was not including help option and help command
+  - pad width calculation was including hidden options and commands
+- improve backwards compatibility for custom command event listeners ([#1403])
+  
+### Deleted
+
+- *Breaking:* `.passCommandToAction()` ([#1409])
+    - no longer needed as action handler is passed options and command
+- *Breaking:* "extra arguments" parameter to action handler ([#1409])
+    - if being used to detect excess arguments, there is now an error available by setting `.allowExcessArguments(false)`
+
+### Migration Tips
+
+The biggest change is the parsed option values. Previously the options were stored by default as properties on the command object, and now the options are stored separately.
+
+If you wish to restore the old behaviour and get running quickly you can call `.storeOptionsAsProperties()`. 
+To allow you to move to the new code patterns incrementally, the action handler will be passed the command _twice_,
+to match the new "options" and "command" parameters (see below).
+
+**program options**
+
+Use the `.opts()` method to access the options. This is available on any command but is used most with the program.
+
+```js
+program.option('-d, --debug');
+program.parse();
+// Old code before Commander 7
+if (program.debug) console.log(`Program name is ${program.name()}`);
+```
+
+```js
+// New code
+const options = program.opts();
+if (options.debug) console.log(`Program name is ${program.name()}`);
+```
+
+**action handler**
+
+The action handler gets passed a parameter for each command-argument you declared. Previously by default the next parameter was the command object with the options as properties. Now the next two parameters are instead the options and the command. If you
+only accessed the options there may be no code changes required.
+
+```js
+program
+  .command('compress <filename>')
+  .option('-t, --trace')
+  // Old code before Commander 7
+  .action((filename, cmd)) => {
+    if (cmd.trace) console.log(`Command name is ${cmd.name()}`);
+  });
+```
+
+```js
+  // New code
+  .action((filename, options, command)) => {
+    if (options.trace) console.log(`Command name is ${command.name()}`);
+  });
+```
+
+If you already set `.storeOptionsAsProperties(false)` you may still need to adjust your code.
+
+```js
+program
+  .command('compress <filename>')
+  .storeOptionsAsProperties(false)
+  .option('-t, --trace')
+  // Old code before Commander 7
+  .action((filename, command)) => {
+    if (command.opts().trace) console.log(`Command name is ${command.name()}`);
+  });
+```
+
+```js
+   // New code
+   .action((filename, options, command)) => {
+      if (command.opts().trace) console.log(`Command name is ${command.name()}`);
+   });
+```

+## [5.0.0] (2020-03-14)
+
+### Added
+
+* support for nested commands with action-handlers ([#1] [#764] [#1149])
+* `.addCommand()` for adding a separately configured command ([#764] [#1149])
+* allow a non-executable to be set as the default command ([#742] [#1149])
+* implicit help command when there are subcommands (previously only if executables) ([#1149])
+* customise implicit help command with `.addHelpCommand()` ([#1149])
+* display error message for unknown subcommand, by default ([#432] [#1088] [#1149])
+* display help for missing subcommand, by default ([#1088] [#1149])
+* combined short options as single argument may include boolean flags and value flag and value (e.g. `-a -b -p 80` can be written as `-abp80`) ([#1145])
+* `.parseOption()` includes short flag and long flag expansions ([#1145])
+* `.helpInformation()` returns help text as a string, previously a private routine ([#1169])
+* `.parse()` implicitly uses `process.argv` if arguments not specified ([#1172])
+* optionally specify where `.parse()` arguments "from", if not following node conventions ([#512] [#1172])
+* suggest help option along with unknown command error ([#1179])
+* TypeScript definition for `commands` property of `Command` ([#1184])
+* export `program` property ([#1195])

+
+### Fixed
+
+* preserve argument order in subcommands ([#508] [#962] [#1138])
+* do not emit `command:*` for executable subcommands ([#809] [#1149])
+* action handler called whether or not there are non-option arguments ([#1062] [#1149])
+* combining option short flag and value in single argument now works for subcommands ([#1145])
+* only add implicit help command when it will not conflict with other uses of argument ([#1153] [#1149])
+* implicit help command works with command aliases ([#948] [#1149])
+* options are validated whether or not there is an action handler ([#1149])
+
+### Changed
+
+* *Breaking* `.args` contains command arguments with just recognised options removed ([#1032] [#1138])
+* *Breaking* display error if required argument for command is missing ([#995] [#1149])
+* tighten TypeScript definition of custom option processing function passed to `.option()` ([#1119])
+* *Breaking* `.allowUnknownOption()` ([#802] [#1138])
+  * unknown options included in arguments passed to command action handler
+  * unknown options included in `.args`
+* only recognised option short flags and long flags are expanded (e.g. `-ab` or `--foo=bar`) ([#1145])
+* *Breaking* `.parseOptions()` ([#1138])
+  * `args` in returned result renamed `operands` and does not include anything after first unknown option
+  * `unknown` in returned result has arguments after first unknown option including operands, not just options and values
+* *Breaking* `.on('command:*', callback)` and other command events passed (changed) results from `.parseOptions`, i.e. operands and unknown  ([#1138])
+* refactor Option from prototype to class ([#1133])
+* refactor Command from prototype to class ([#1159])
+* changes to error handling ([#1165])
+  * throw for author error, not just display message
+  * preflight for variadic error
+  * add tips to missing subcommand executable
+* TypeScript fluent return types changed to be more subclass friendly, return `this` rather than `Command` ([#1180])
+* `.parseAsync` returns `Promise<this>` to be consistent with `.parse()` ([#1180])
+* update dependencies
+
+### Removed
+
+* removed EventEmitter from TypeScript definition for Command, eliminating implicit peer dependency on `@types/node` ([#1146])
+* removed private function `normalize` (the functionality has been integrated into `parseOptions`) ([#1145])
+* `parseExpectedArgs` is now private ([#1149])
+
+### Migration Tips
+
+If you use `.on('command:*')` or more complicated tests to detect an unrecognised subcommand, you may be able to delete the code and rely on the default behaviour.
+
+If you use `program.args` or more complicated tests to detect a missing subcommand, you may be able to delete the code and rely on the default behaviour.
+
+If you use `.command('*')` to add a default command, you may be be able to switch to `isDefault:true` with a named command.
+
+If you want to continue combining short options with optional values as though they were boolean flags, set `combineFlagAndOptionalValue(false)`
+to expand `-fb` to `-f -b` rather than `-f b`.

+
+## Installation
+
+```bash
+npm install commander
+```
+
+## Declaring _program_ variable
+
+Commander exports a global object which is convenient for quick programs.
+This is used in the examples in this README for brevity.
+
+```js
+const { program } = require('commander');
+program.version('0.0.1');
+```
+
+For larger programs which may use commander in multiple ways, including unit testing, it is better to create a local Command object to use.
+
+```js
+const { Command } = require('commander');
+const program = new Command();
+program.version('0.0.1');
+```
+
+For named imports in ECMAScript modules, import from `commander/esm.mjs`.
+
+```js
+// index.mjs
+import { Command } from 'commander/esm.mjs';
+const program = new Command();
+```
+
+And in TypeScript:
+
+```ts
+// index.ts
+import { Command } from 'commander';
+const program = new Command();
+```
+
+
+## Options
+
+Options are defined with the `.option()` method, also serving as documentation for the options. Each option can have a short flag (single character) and a long name, separated by a comma or space or vertical bar ('|').
+
+The parsed options can be accessed by calling `.opts()` on a `Command` object, and are passed to the action handler. Multi-word options such as "--template-engine" are camel-cased, becoming `program.opts().templateEngine` etc.
+
+Multiple short flags may optionally be combined in a single argument following the dash: boolean flags, followed by a single option taking a value (possibly followed by the value).
+For example `-a -b -p 80` may be written as `-ab -p80` or even `-abp80`.
+
+You can use `--` to indicate the end of the options, and any remaining arguments will be used without being interpreted.
+
+By default options on the command line are not positional, and can be specified before or after other arguments.
+
+### Common option types, boolean and value
+
+The two most used option types are a boolean option, and an option which takes its value
+from the following argument (declared with angle brackets like `--expect <value>`). Both are `undefined` unless specified on command line.  
+
+Example file: [options-common.js](./examples/options-common.js)
+
+```js
+program
+  .option('-d, --debug', 'output extra debugging')
+  .option('-s, --small', 'small pizza size')
+  .option('-p, --pizza-type <type>', 'flavour of pizza');
+
+program.parse(process.argv);
+
+const options = program.opts();
+if (options.debug) console.log(options);
+console.log('pizza details:');
+if (options.small) console.log('- small pizza size');
+if (options.pizzaType) console.log(`- ${options.pizzaType}`);
+```
+
+```bash
+$ pizza-options -d
+{ debug: true, small: undefined, pizzaType: undefined }
+pizza details:
+$ pizza-options -p
+error: option '-p, --pizza-type <type>' argument missing
+$ pizza-options -ds -p vegetarian
+{ debug: true, small: true, pizzaType: 'vegetarian' }
+pizza details:
+- small pizza size
+- vegetarian
+$ pizza-options --pizza-type=cheese
+pizza details:
+- cheese
+```
+
+`program.parse(arguments)` processes the arguments, leaving any args not consumed by the program options in the `program.args` array. The parameter is optional and defaults to `process.argv`.
+
+### Default option value
+
+You can specify a default value for an option which takes a value.
+
+Example file: [options-defaults.js](./examples/options-defaults.js)
+
+```js
+program
+  .option('-c, --cheese <type>', 'add the specified type of cheese', 'blue');
+
+program.parse();
+
+console.log(`cheese: ${program.opts().cheese}`);
+```
+
+```bash
+$ pizza-options
+cheese: blue
+$ pizza-options --cheese stilton
+cheese: stilton
+```
+
+### Other option types, negatable boolean and boolean|value
+
+You can define a boolean option long name with a leading `no-` to set the option value to false when used.
+Defined alone this also makes the option true by default.
+
+If you define `--foo` first, adding `--no-foo` does not change the default value from what it would
+otherwise be. You can specify a default boolean value for a boolean option and it can be overridden on command line.
+
+Example file: [options-negatable.js](./examples/options-negatable.js)
+
+```js
+program
+  .option('--no-sauce', 'Remove sauce')
+  .option('--cheese <flavour>', 'cheese flavour', 'mozzarella')
+  .option('--no-cheese', 'plain with no cheese')
+  .parse();
+
+const options = program.opts();
+const sauceStr = options.sauce ? 'sauce' : 'no sauce';
+const cheeseStr = (options.cheese === false) ? 'no cheese' : `${options.cheese} cheese`;
+console.log(`You ordered a pizza with ${sauceStr} and ${cheeseStr}`);
+```
+
+```bash
+$ pizza-options
+You ordered a pizza with sauce and mozzarella cheese
+$ pizza-options --sauce
+error: unknown option '--sauce'
+$ pizza-options --cheese=blue
+You ordered a pizza with sauce and blue cheese
+$ pizza-options --no-sauce --no-cheese
+You ordered a pizza with no sauce and no cheese
+```
+
+You can specify an option which may be used as a boolean option but may optionally take an option-argument
+(declared with square brackets like `--optional [value]`).
+
+Example file: [options-boolean-or-value.js](./examples/options-boolean-or-value.js)
+
+```js
+program
+  .option('-c, --cheese [type]', 'Add cheese with optional type');
+
+program.parse(process.argv);
+
+const options = program.opts();
+if (options.cheese === undefined) console.log('no cheese');
+else if (options.cheese === true) console.log('add cheese');
+else console.log(`add cheese type ${options.cheese}`);
+```
+
+```bash
+$ pizza-options
+no cheese
+$ pizza-options --cheese
+add cheese
+$ pizza-options --cheese mozzarella
+add cheese type mozzarella
+```
+
+For information about possible ambiguous cases, see [options taking varying arguments](./docs/options-taking-varying-arguments.md).
+
+### Required option
+
+You may specify a required (mandatory) option using `.requiredOption`. The option must have a value after parsing, usually specified on the command line, or perhaps from a default value (say from environment). The method is otherwise the same as `.option` in format, taking flags and description, and optional default value or custom processing.
+
+Example file: [options-required.js](./examples/options-required.js)
+
+```js
+program
+  .requiredOption('-c, --cheese <type>', 'pizza must have cheese');
+
+program.parse();
+```
+
+```bash
+$ pizza
+error: required option '-c, --cheese <type>' not specified
+```
+
+### Variadic option
+
+You may make an option variadic by appending `...` to the value placeholder when declaring the option. On the command line you
+can then specify multiple option-arguments, and the parsed option value will be an array. The extra arguments
+are read until the first argument starting with a dash. The special argument `--` stops option processing entirely. If a value
+is specified in the same argument as the option then no further values are read.
+
+Example file: [options-variadic.js](./examples/options-variadic.js)
+
+```js
+program
+  .option('-n, --number <numbers...>', 'specify numbers')
+  .option('-l, --letter [letters...]', 'specify letters');
+
+program.parse();
+
+console.log('Options: ', program.opts());
+console.log('Remaining arguments: ', program.args);
+```
+
+```bash
+$ collect -n 1 2 3 --letter a b c
+Options:  { number: [ '1', '2', '3' ], letter: [ 'a', 'b', 'c' ] }
+Remaining arguments:  []
+$ collect --letter=A -n80 operand
+Options:  { number: [ '80' ], letter: [ 'A' ] }
+Remaining arguments:  [ 'operand' ]
+$ collect --letter -n 1 -n 2 3 -- operand
+Options:  { number: [ '1', '2', '3' ], letter: true }
+Remaining arguments:  [ 'operand' ]
+```
+
+For information about possible ambiguous cases, see [options taking varying arguments](./docs/options-taking-varying-arguments.md).
+
+### Version option
+
+The optional `version` method adds handling for displaying the command version. The default option flags are `-V` and `--version`, and when present the command prints the version number and exits.
+
+```js
+program.version('0.0.1');
+```
+
+```bash
+$ ./examples/pizza -V
+0.0.1
+```
+
+You may change the flags and description by passing additional parameters to the `version` method, using
+the same syntax for flags as the `option` method.
+
+```js
+program.version('0.0.1', '-v, --vers', 'output the current version');
+```
+
+### More configuration
+
+You can add most options using the `.option()` method, but there are some additional features available
+by constructing an `Option` explicitly for less common cases.
+
+Example file: [options-extra.js](./examples/options-extra.js)
+
+```js
+program
+  .addOption(new Option('-s, --secret').hideHelp())
+  .addOption(new Option('-t, --timeout <delay>', 'timeout in seconds').default(60, 'one minute'))
+  .addOption(new Option('-d, --drink <size>', 'drink size').choices(['small', 'medium', 'large']));
+```
+
+```bash
+$ extra --help
+Usage: help [options]
+
+Options:
+  -t, --timeout <delay>  timeout in seconds (default: one minute)
+  -d, --drink <size>     drink cup size (choices: "small", "medium", "large")
+  -h, --help             display help for command
+
+$ extra --drink huge
+error: option '-d, --drink <size>' argument 'huge' is invalid. Allowed choices are small, medium, large.
+```
+
+### Custom option processing
+
+You may specify a function to do custom processing of option-arguments. The callback function receives two parameters,
+the user specified option-argument and the previous value for the option. It returns the new value for the option.
+
+This allows you to coerce the option-argument to the desired type, or accumulate values, or do entirely custom processing.
+
+You can optionally specify the default/starting value for the option after the function parameter.
+
+Example file: [options-custom-processing.js](./examples/options-custom-processing.js)
+
+```js
+function myParseInt(value, dummyPrevious) {
+  // parseInt takes a string and a radix
+  const parsedValue = parseInt(value, 10);
+  if (isNaN(parsedValue)) {
+    throw new commander.InvalidOptionArgumentError('Not a number.');
+  }
+  return parsedValue;
+}
+
+function increaseVerbosity(dummyValue, previous) {
+  return previous + 1;
+}
+
+function collect(value, previous) {
+  return previous.concat([value]);
+}
+
+function commaSeparatedList(value, dummyPrevious) {
+  return value.split(',');
+}
+
+program
+  .option('-f, --float <number>', 'float argument', parseFloat)
+  .option('-i, --integer <number>', 'integer argument', myParseInt)
+  .option('-v, --verbose', 'verbosity that can be increased', increaseVerbosity, 0)
+  .option('-c, --collect <value>', 'repeatable value', collect, [])
+  .option('-l, --list <items>', 'comma separated list', commaSeparatedList)
+;
+
+program.parse();
+
+const options = program.opts();
+if (options.float !== undefined) console.log(`float: ${options.float}`);
+if (options.integer !== undefined) console.log(`integer: ${options.integer}`);
+if (options.verbose > 0) console.log(`verbosity: ${options.verbose}`);
+if (options.collect.length > 0) console.log(options.collect);
+if (options.list !== undefined) console.log(options.list);
+```
+
+```bash
+$ custom -f 1e2
+float: 100
+$ custom --integer 2
+integer: 2
+$ custom -v -v -v
+verbose: 3
+$ custom -c a -c b -c c
+[ 'a', 'b', 'c' ]
+$ custom --list x,y,z
+[ 'x', 'y', 'z' ]
+```
+
+## Commands
+
+You can specify (sub)commands using `.command()` or `.addCommand()`. There are two ways these can be implemented: using an action handler attached to the command, or as a stand-alone executable file (described in more detail later). The subcommands may be nested ([example](./examples/nestedCommands.js)).
+
+In the first parameter to `.command()` you specify the command name and any command-arguments. The arguments may be `<required>` or `[optional]`, and the last argument may also be `variadic...`.
+
+You can use `.addCommand()` to add an already configured subcommand to the program.
+
+For example:
+
+```js
+// Command implemented using action handler (description is supplied separately to `.command`)
+// Returns new command for configuring.
+program
+  .command('clone <source> [destination]')
+  .description('clone a repository into a newly created directory')
+  .action((source, destination) => {
+    console.log('clone command called');
+  });
+
+// Command implemented using stand-alone executable file (description is second parameter to `.command`)
+// Returns `this` for adding more commands.
+program
+  .command('start <service>', 'start named service')
+  .command('stop [service]', 'stop named service, or all if no name supplied');
+
+// Command prepared separately.
+// Returns `this` for adding more commands.
+program
+  .addCommand(build.makeBuildCommand());
+```
+
+Configuration options can be passed with the call to `.command()` and `.addCommand()`. Specifying `hidden: true` will 
+remove the command from the generated help output. Specifying `isDefault: true` will run the subcommand if no other
+subcommand is specified ([example](./examples/defaultCommand.js)).
+
+### Specify the argument syntax
+
+You use `.arguments` to specify the expected command-arguments for the top-level command, and for subcommands they are usually
+included in the `.command` call. Angled brackets (e.g. `<required>`) indicate required command-arguments.
+Square brackets (e.g. `[optional]`) indicate optional command-arguments.
+You can optionally describe the arguments in the help by supplying a hash as second parameter to `.description()`.
+
+Example file: [arguments.js](./examples/arguments.js)
+
+```js
+program
+  .version('0.1.0')
+  .arguments('<username> [password]')
+  .description('test command', {
+    username: 'user to login',
+    password: 'password for user, if required'
+  })
+  .action((username, password) => {
+    console.log('username:', username);
+    console.log('environment:', password || 'no password given');
+  });
+```
+
+ The last argument of a command can be variadic, and only the last argument.  To make an argument variadic you
+ append `...` to the argument name. For example:
+
+```js
+program
+  .version('0.1.0')
+  .command('rmdir <dirs...>')
+  .action(function (dirs) {
+    dirs.forEach((dir) => {
+      console.log('rmdir %s', dir);
+    });
+  });
+```
+
+The variadic argument is passed to the action handler as an array.
+
+### Action handler
+
+The action handler gets passed a parameter for each command-argument you declared, and two additional parameters
+which are the parsed options and the command object itself. 
+
+Example file: [thank.js](./examples/thank.js)
+
+```js
+program
+  .arguments('<name>')
+  .option('-t, --title <honorific>', 'title to use before name')
+  .option('-d, --debug', 'display some debugging')
+  .action((name, options, command) => {
+    if (options.debug) {
+      console.error('Called %s with options %o', command.name(), options);
+    }
+    const title = options.title ? `${options.title} ` : '';
+    console.log(`Thank-you ${title}${name}`);
+  });
+```
+
+You may supply an `async` action handler, in which case you call `.parseAsync` rather than `.parse`.
+
+```js
+async function run() { /* code goes here */ }
+
+async function main() {
+  program
+    .command('run')
+    .action(run);
+  await program.parseAsync(process.argv);
+}
+```
+
+A command's options and arguments on the command line are validated when the command is used. Any unknown options or missing arguments will be reported as an error. You can suppress the unknown option checks with `.allowUnknownOption()`. By default it is not an error to
+pass more arguments than declared, but you can make this an error with `.allowExcessArguments(false)`.
+
+### Stand-alone executable (sub)commands
+
+When `.command()` is invoked with a description argument, this tells Commander that you're going to use stand-alone executables for subcommands.
+Commander will search the executables in the directory of the entry script (like `./examples/pm`) with the name `program-subcommand`, like `pm-install`, `pm-search`.
+You can specify a custom name with the `executableFile` configuration option.
+
+You handle the options for an executable (sub)command in the executable, and don't declare them at the top-level.
+
+Example file: [pm](./examples/pm)
+
+```js
+program
+  .version('0.1.0')
+  .command('install [name]', 'install one or more packages')
+  .command('search [query]', 'search with optional query')
+  .command('update', 'update installed packages', { executableFile: 'myUpdateSubCommand' })
+  .command('list', 'list packages installed', { isDefault: true });
+
+program.parse(process.argv);
+```
+
+If the program is designed to be installed globally, make sure the executables have proper modes, like `755`.
+
+## Automated help
+
+The help information is auto-generated based on the information commander already knows about your program. The default
+help option is `-h,--help`.
+
+Example file: [pizza](./examples/pizza)
+
+```bash
+$ node ./examples/pizza --help
+Usage: pizza [options]
+
+An application for pizza ordering
+
+Options:
+  -p, --peppers        Add peppers
+  -c, --cheese <type>  Add the specified type of cheese (default: "marble")
+  -C, --no-cheese      You do not want any cheese
+  -h, --help           display help for command
+```
+
+A `help` command is added by default if your command has subcommands. It can be used alone, or with a subcommand name to show
+further help for the subcommand. These are effectively the same if the `shell` program has implicit help:
+
+```bash
+shell help
+shell --help
+
+shell help spawn
+shell spawn --help
+```
+
+### Custom help
+
+You can add extra text to be displayed along with the built-in help. 
+
+Example file: [custom-help](./examples/custom-help)
+
+```js
+program
+  .option('-f, --foo', 'enable some foo');
+
+program.addHelpText('after', `
+
+Example call:
+  $ custom-help --help`);
+```
+
+Yields the following help output:
+
+```Text
+Usage: custom-help [options]
+
+Options:
+  -f, --foo   enable some foo
+  -h, --help  display help for command
+
+Example call:
+  $ custom-help --help
+```
+
+The positions in order displayed are:
+
+- `beforeAll`: add to the program for a global banner or header
+- `before`: display extra information before built-in help
+- `after`: display extra information after built-in help
+- `afterAll`: add to the program for a global footer (epilog)
+
+The positions "beforeAll" and "afterAll" apply to the command and all its subcommands. 
+
+The second parameter can be a string, or a function returning a string. The function is passed a context object for your convenience. The properties are:
+
+- error: a boolean for whether the help is being displayed due to a usage error
+- command: the Command which is displaying the help
+
+### Display help from code
+
+`.help()`: display help information and exit immediately. You can optionally pass `{ error: true }` to display on stderr and exit with an error status.
+
+`.outputHelp()`: output help information without exiting. You can optionally pass `{ error: true }` to display on stderr.
+
+`.helpInformation()`: get the built-in command help information as a string for processing or displaying yourself.
+
+### .usage and .name
+
+These allow you to customise the usage description in the first line of the help. The name is otherwise
+deduced from the (full) program arguments. Given:
+
+```js
+program
+  .name("my-command")
+  .usage("[global options] command")
+```
+
+The help will start with:
+
+```Text
+Usage: my-command [global options] command
+```
+
+### .helpOption(flags, description)
+
+By default every command has a help option. Override the default help flags and description. Pass false to disable the built-in help option.
+
+```js
+program
+  .helpOption('-e, --HELP', 'read more information');
+```
+
+### .addHelpCommand()
+
+A help command is added by default if your command has subcommands. You can explicitly turn on or off the implicit help command with `.addHelpCommand()` and `.addHelpCommand(false)`.
+
+You can both turn on and customise the help command by supplying the name and description:
+
+```js
+program.addHelpCommand('assist [command]', 'show assistance');
+```
+
+### More configuration
+
+The built-in help is formatted using the Help class.
+You can configure the Help behaviour by modifying data properties and methods using `.configureHelp()`, or by subclassing using `.createHelp()` if you prefer.
+
+The data properties are:
+
+- `helpWidth`: specify the wrap width, useful for unit tests
+- `sortSubcommands`: sort the subcommands alphabetically
+- `sortOptions`: sort the options alphabetically
+
+There are methods getting the visible lists of arguments, options, and subcommands. There are methods for formatting the items in the lists, with each item having a _term_ and _description_. Take a look at `.formatHelp()` to see how they are used.
+
+Example file: [configure-help.js](./examples/configure-help.js)
+
+```
+program.configureHelp({
+  sortSubcommands: true,
+  subcommandTerm: (cmd) => cmd.name() // Just show the name, instead of short usage.
+});
+```
+
+## Custom event listeners
+
+You can execute custom actions by listening to command and option events.
+
+```js
+program.on('option:verbose', function () {
+  process.env.VERBOSE = this.opts().verbose;
+});
+
+program.on('command:*', function (operands) {
+  console.error(`error: unknown command '${operands[0]}'`);
+  const availableCommands = program.commands.map(cmd => cmd.name());
+  mySuggestBestMatch(operands[0], availableCommands);
+  process.exitCode = 1;
+});
+```
+
+## Bits and pieces
+
+### .parse() and .parseAsync()
+
+The first argument to `.parse` is the array of strings to parse. You may omit the parameter to implicitly use `process.argv`.
+
+If the arguments follow different conventions than node you can pass a `from` option in the second parameter:
+
+- 'node': default, `argv[0]` is the application and `argv[1]` is the script being run, with user parameters after that
+- 'electron': `argv[1]` varies depending on whether the electron application is packaged
+- 'user': all of the arguments from the user
+
+For example:
+
+```js
+program.parse(process.argv); // Explicit, node conventions
+program.parse(); // Implicit, and auto-detect electron
+program.parse(['-f', 'filename'], { from: 'user' });
+```
+
+### Parsing Configuration
+
+If the default parsing does not suit your needs, there are some behaviours to support other usage patterns.
+
+By default program options are recognised before and after subcommands. To only look for program options before subcommands, use `.enablePositionalOptions()`. This lets you use
+an option for a different purpose in subcommands.
+
+Example file: [positional-options.js](./examples/positional-options.js)
+
+With positional options, the `-b` is a program option in the first line and a subcommand option in the second line:
+
+```sh
+program -b subcommand
+program subcommand -b
+```
+
+By default options are recognised before and after command-arguments. To only process options that come
+before the command-arguments, use `.passThroughOptions()`. This lets you pass the  arguments and following options through to another program
+without needing to use `--` to end the option processing. 
+To use pass through options in a subcommand, the program needs to enable positional options.
+
+Example file: [pass-through-options.js](./examples/pass-through-options.js)
+
+With pass through options, the `--port=80` is a program option in the first line and passed through as a command-argument in the second line:
+
+```sh
+program --port=80 arg
+program arg --port=80
+```
+
+By default the option processing shows an error for an unknown option. To have an unknown option treated as an ordinary command-argument and continue looking for options, use `.allowUnknownOption()`. This lets you mix known and unknown options.
+
+By default the argument processing does not display an error for more command-arguments than expected.
+To display an error for excess arguments, use`.allowExcessArguments(false)`.
+
+### Legacy options as properties 
+
+Before Commander 7, the option values were stored as properties on the command.
+This was convenient to code but the downside was possible clashes with
+existing properties of `Command`. You can revert to the old behaviour to run unmodified legacy code by using `.storeOptionsAsProperties()`.
+
+```js
+program
+  .storeOptionsAsProperties()
+  .option('-d, --debug')
+  .action((commandAndOptions) => {
+    if (commandAndOptions.debug) {
+      console.error(`Called ${commandAndOptions.name()}`);
+    }
+  });
+```
+
+### TypeScript
+
+If you use `ts-node` and  stand-alone executable subcommands written as `.ts` files, you need to call your program through node to get the subcommands called correctly. e.g.
+
+```bash
+node -r ts-node/register pm.ts
+```
+
+### createCommand()
+
+This factory function creates a new command. It is exported and may be used instead of using `new`, like:
+
+```js
+const { createCommand } = require('commander');
+const program = createCommand();
+```
+
+`createCommand` is also a method of the Command object, and creates a new command rather than a subcommand. This gets used internally
+when creating subcommands using `.command()`, and you may override it to
+customise the new subcommand (example file [custom-command-class.js](./examples/custom-command-class.js)).
+
+### Node options such as `--harmony`
+
+You can enable `--harmony` option in two ways:
+
+- Use `#! /usr/bin/env node --harmony` in the subcommands scripts. (Note Windows does not support this pattern.)
+- Use the `--harmony` option when call the command, like `node --harmony examples/pm publish`. The `--harmony` option will be preserved when spawning subcommand process.
+
+### Debugging stand-alone executable subcommands
+
+An executable subcommand is launched as a separate child process.
+
+If you are using the node inspector for [debugging](https://nodejs.org/en/docs/guides/debugging-getting-started/) executable subcommands using `node --inspect` et al,
+the inspector port is incremented by 1 for the spawned subcommand.
+
+If you are using VSCode to debug executable subcommands you need to set the `"autoAttachChildProcesses": true` flag in your launch.json configuration.
+
+### Override exit and output handling
+
+By default Commander calls `process.exit` when it detects errors, or after displaying the help or version. You can override
+this behaviour and optionally supply a callback. The default override throws a `CommanderError`.
+
+The override callback is passed a `CommanderError` with properties `exitCode` number, `code` string, and `message`. The default override behaviour is to throw the error, except for async handling of executable subcommand completion which carries on. The normal display of error messages or version or help
+is not affected by the override which is called after the display.
+
+```js
+program.exitOverride();
+
+try {
+  program.parse(process.argv);
+} catch (err) {
+  // custom processing...
+}
+```
+
+By default Commander is configured for a command-line application and writes to stdout and stderr.
+You can modify this behaviour for custom applications. In addition, you can modify the display of error messages.
+
+Example file: [configure-output.js](./examples/configure-output.js)
+
+
+```js
+function errorColor(str) {
+  // Add ANSI escape codes to display text in red.
+  return `\x1b[31m${str}\x1b[0m`;
+}
+
+program
+  .configureOutput({
+    // Visibly override write routines as example!
+    writeOut: (str) => process.stdout.write(`[OUT] ${str}`),
+    writeErr: (str) => process.stdout.write(`[ERR] ${str}`),
+    // Highlight errors in color.
+    outputError: (str, write) => write(errorColor(str))
+  });
+```

+## Examples
+
+In a single command program, you might not need an action handler.
+
+Example file: [pizza](./examples/pizza)
+
+```js
+const { program } = require('commander');
+
+program
+  .description('An application for pizza ordering')
+  .option('-p, --peppers', 'Add peppers')
+  .option('-c, --cheese <type>', 'Add the specified type of cheese', 'marble')
+  .option('-C, --no-cheese', 'You do not want any cheese');
+
+program.parse();
+
+const options = program.opts();
+console.log('you ordered a pizza with:');
+if (options.peppers) console.log('  - peppers');
+const cheese = !options.cheese ? 'no' : options.cheese;
+console.log('  - %s cheese', cheese);
+```
+
+In a multi-command program, you will have action handlers for each command (or stand-alone executables for the commands).
+
+Example file: [deploy](./examples/deploy)
+
+```js
+const { Command } = require('commander');
+const program = new Command();
+
+program
+  .version('0.0.1')
+  .option('-c, --config <path>', 'set config path', './deploy.conf');
+
+program
+  .command('setup [env]')
+  .description('run setup commands for all envs')
+  .option('-s, --setup_mode <mode>', 'Which setup mode to use', 'normal')
+  .action((env, options) => {
+    env = env || 'all';
+    console.log('read config from %s', program.opts().config);
+    console.log('setup for %s env(s) with %s mode', env, options.setup_mode);
+  });
+
+program
+  .command('exec <script>')
+  .alias('ex')
+  .description('execute the given remote cmd')
+  .option('-e, --exec_mode <mode>', 'Which exec mode to use', 'fast')
+  .action((script, options) => {
+    console.log('read config from %s', program.opts().config);
+    console.log('exec "%s" using %s mode and config %s', script, options.exec_mode, program.opts().config);
+  }).addHelpText('after', `
+Examples:
+  $ deploy exec sequential
+  $ deploy exec async`
+  );
+  
+program.parse(process.argv);
+```
+
+More samples can be found in the [examples](https://github.com/tj/commander.js/tree/master/examples) directory.
+
