+# Arg
+
+`arg` is an unopinionated, no-frills CLI argument parser.
+
+## Installation
+
+```bash
+npm install arg
+```
+
+## Usage
+
+`arg()` takes either 1 or 2 arguments:
+
+1. Command line specification object (see below)
+2. Parse options (_Optional_, defaults to `{permissive: false, argv: process.argv.slice(2), stopAtPositional: false}`)
+
+It returns an object with any values present on the command-line (missing options are thus
+missing from the resulting object). Arg performs no validation/requirement checking - we
+leave that up to the application.
+
+All parameters that aren't consumed by options (commonly referred to as "extra" parameters)
+are added to `result._`, which is _always_ an array (even if no extra parameters are passed,
+in which case an empty array is returned).
+
+```javascript
+const arg = require('arg');
+
+// `options` is an optional parameter
+const args = arg(
+	spec,
+	(options = { permissive: false, argv: process.argv.slice(2) })
+);
+```
+
+For example:
+
+```console
+$ node ./hello.js --verbose -vvv --port=1234 -n 'My name' foo bar --tag qux --tag=qix -- --foobar
+```
+
+```javascript
+// hello.js
+const arg = require('arg');
+
+const args = arg({
+	// Types
+	'--help': Boolean,
+	'--version': Boolean,
+	'--verbose': arg.COUNT, // Counts the number of times --verbose is passed
+	'--port': Number, // --port <number> or --port=<number>
+	'--name': String, // --name <string> or --name=<string>
+	'--tag': [String], // --tag <string> or --tag=<string>
+
+	// Aliases
+	'-v': '--verbose',
+	'-n': '--name', // -n <string>; result is stored in --name
+	'--label': '--name' // --label <string> or --label=<string>;
+	//     result is stored in --name
+});
+
+console.log(args);
+/*
+{
+	_: ["foo", "bar", "--foobar"],
+	'--port': 1234,
+	'--verbose': 4,
+	'--name': "My name",
+	'--tag': ["qux", "qix"]
+}
+*/
+```
+
+The values for each key=&gt;value pair is either a type (function or [function]) or a string (indicating an alias).
+
+- In the case of a function, the string value of the argument's value is passed to it,
+  and the return value is used as the ultimate value.
+
+- In the case of an array, the only element _must_ be a type function. Array types indicate
+  that the argument may be passed multiple times, and as such the resulting value in the returned
+  object is an array with all of the values that were passed using the specified flag.
+
+- In the case of a string, an alias is established. If a flag is passed that matches the _key_,
+  then the _value_ is substituted in its place.
+
+Type functions are passed three arguments:
+
+1. The parameter value (always a string)
+2. The parameter name (e.g. `--label`)
+3. The previous value for the destination (useful for reduce-like operations or for supporting `-v` multiple times, etc.)
+
+This means the built-in `String`, `Number`, and `Boolean` type constructors "just work" as type functions.
+
+Note that `Boolean` and `[Boolean]` have special treatment - an option argument is _not_ consumed or passed, but instead `true` is
+returned. These options are called "flags".
+
+For custom handlers that wish to behave as flags, you may pass the function through `arg.flag()`:
+
+```javascript
+const arg = require('arg');
+
+const argv = [
+	'--foo',
+	'bar',
+	'-ff',
+	'baz',
+	'--foo',
+	'--foo',
+	'qux',
+	'-fff',
+	'qix'
+];
+
+function myHandler(value, argName, previousValue) {
+	/* `value` is always `true` */
+	return 'na ' + (previousValue || 'batman!');
+}
+
+const args = arg(
+	{
+		'--foo': arg.flag(myHandler),
+		'-f': '--foo'
+	},
+	{
+		argv
+	}
+);
+
+console.log(args);
+/*
+{
+	_: ['bar', 'baz', 'qux', 'qix'],
+	'--foo': 'na na na na na na na na batman!'
+}
+*/
+```
+
+As well, `arg` supplies a helper argument handler called `arg.COUNT`, which equivalent to a `[Boolean]` argument's `.length`
+property - effectively counting the number of times the boolean flag, denoted by the key, is passed on the command line..
+For example, this is how you could implement `ssh`'s multiple levels of verbosity (`-vvvv` being the most verbose).
+
+```javascript
+const arg = require('arg');
+
+const argv = ['-AAAA', '-BBBB'];
+
+const args = arg(
+	{
+		'-A': arg.COUNT,
+		'-B': [Boolean]
+	},
+	{
+		argv
+	}
+);
+
+console.log(args);
+/*
+{
+	_: [],
+	'-A': 4,
+	'-B': [true, true, true, true]
+}
+*/
+```
+
+### Options
+
+If a second parameter is specified and is an object, it specifies parsing options to modify the behavior of `arg()`.
+
+#### `argv`
+
+If you have already sliced or generated a number of raw arguments to be parsed (as opposed to letting `arg`
+slice them from `process.argv`) you may specify them in the `argv` option.
+
+For example:
+
+```javascript
+const args = arg(
+	{
+		'--foo': String
+	},
+	{
+		argv: ['hello', '--foo', 'world']
+	}
+);
+```
+
+results in:
+
+```javascript
+const args = {
+	_: ['hello'],
+	'--foo': 'world'
+};
+```
+
+#### `permissive`
+
+When `permissive` set to `true`, `arg` will push any unknown arguments
+onto the "extra" argument array (`result._`) instead of throwing an error about
+an unknown flag.
+
+For example:
+
+```javascript
+const arg = require('arg');
+
+const argv = [
+	'--foo',
+	'hello',
+	'--qux',
+	'qix',
+	'--bar',
+	'12345',
+	'hello again'
+];
+
+const args = arg(
+	{
+		'--foo': String,
+		'--bar': Number
+	},
+	{
+		argv,
+		permissive: true
+	}
+);
+```
+
+results in:
+
+```javascript
+const args = {
+	_: ['--qux', 'qix', 'hello again'],
+	'--foo': 'hello',
+	'--bar': 12345
+};
+```
+
+#### `stopAtPositional`
+
+When `stopAtPositional` is set to `true`, `arg` will halt parsing at the first
+positional argument.
+
+For example:
+
+```javascript
+const arg = require('arg');
+
+const argv = ['--foo', 'hello', '--bar'];
+
+const args = arg(
+	{
+		'--foo': Boolean,
+		'--bar': Boolean
+	},
+	{
+		argv,
+		stopAtPositional: true
+	}
+);
+```
+
+results in:
+
+```javascript
+const args = {
+	_: ['hello', '--bar'],
+	'--foo': true
+};
+```
+
+### Errors
+
+Some errors that `arg` throws provide a `.code` property in order to aid in recovering from user error, or to
+differentiate between user error and developer error (bug).
+
+##### ARG_UNKNOWN_OPTION
+
+If an unknown option (not defined in the spec object) is passed, an error with code `ARG_UNKNOWN_OPTION` will be thrown:
+
+```js
+// cli.js
+try {
+	require('arg')({ '--hi': String });
+} catch (err) {
+	if (err.code === 'ARG_UNKNOWN_OPTION') {
+		console.log(err.message);
+	} else {
+		throw err;
+	}
+}
+```
+
+```shell
+node cli.js --extraneous true
+Unknown or unexpected option: --extraneous
+```
+
+# FAQ
+
+A few questions and answers that have been asked before:
+
+### How do I require an argument with `arg`?
+
+Do the assertion yourself, such as:
+
+```javascript
+const args = arg({ '--name': String });
+
+if (!args['--name']) throw new Error('missing required argument: --name');
+```
