+# node-dashdash changelog
+
+## not yet released
+
+(nothing yet)
+
+## 1.14.1
+
+- [issue #30] Change the output used by dashdash's Bash completion support to
+  indicate "there are no completions for this argument" to cope with different
+  sorting rules on different Bash/platforms. For example:
+
+        $ triton -v -p test2 package get <TAB>          # before
+        ##-no -tritonpackage- completions-##
+
+        $ triton -v -p test2 package get <TAB>          # after
+        ##-no-completion- -results-##
+
+## 1.14.0
+
+- New `synopsisFromOpt(<option spec>)` function. This will be used by
+  [node-cmdln](https://github.com/trentm/node-cmdln) to put together a synopsis
+  of options for a command. Some examples:
+
+        > synopsisFromOpt({names: ['help', 'h'], type: 'bool'});
+        '[ --help | -h ]'
+        > synopsisFromOpt({name: 'file', type: 'string', helpArg: 'FILE'});
+        '[ --file=FILE ]'
+
+
+## 1.13.1
+
+- [issue #20] `bashCompletionSpecFromOptions` breaks on an options array with
+  an empty-string group.
+
+
+## 1.13.0
+
+- Update assert-plus dep to 1.x to get recent fixes (particularly for
+  `assert.optional*`).
+
+- Drop testing (and official support in packages.json#engines) for node 0.8.x.
+  Add testing against node 5.x and 4.x with `make testall`.
+
+- [pull #16] Change the `positiveInteger` type to NOT accept zero (0).
+  For those who might need the old behaviour, see
+  "examples/custom-option-intGteZero.js".  (By Dave Pacheco.)
+
+
+## 1.12.2
+
+- Bash completion: Add `argtypes` to specify the types of positional args.
+  E.g. this would allow you to have an `ssh` command with `argtypes = ['host',
+  'cmd']` for bash completion. You then have to provide Bash functions to
+  handle completing those types via the `specExtra` arg. See
+  "[examples/ddcompletion.js](examples/ddcompletion.js)" for an example.
+
+- Bash completion: Tweak so that options or only offered as completions when
+  there is a leading '-'. E.g. `mytool <TAB>` does NOT offer options, `mytool
+  -<TAB>` *does*. Without this, a tool with options would never be able to
+  fallback to Bash's "default" completion. For example `ls <TAB>` wouldn't
+  result in filename completion. Now it will.
+
+- Bash completion: A workaround for not being able to explicitly have *no*
+  completion results. Because dashdash's completion uses `complete -o default`,
+  we fallback to Bash's "default" completion (typically for filename
+  completion). Before this change, an attempt to explicitly say "there are
+  no completions that match" would unintentionally trigger filename completion.
+  Instead as a workaround we return:
+
+        $ ddcompletion --none <TAB>         # the 'none' argtype
+        ##-no           completions-##
+
+        $ ddcompletion                      # a custom 'fruit' argtype
+        apple   banana  orange
+        $ ddcompletion z
+        ##-no           -fruit-         completions-##
+
+  This is a bit of a hack, but IMO a better experience than the surprise
+  of matching a local filename beginning with 'z', which isn't, in this
+  case, a "fruit".
+
+## 1.12.1
+
+- Bash completion: Document `<option spec>.completionType`. Add `includeHidden`
+  option to `bashCompletionSpecFromOptions()`. Add support for dealing with
+  hidden subcmds.
+
+
+## 1.12.0
+
+- Support for generating Bash completion files. See the "Bash completion"
+  section of the README.md and "examples/ddcompletion.js" for an example.
+
+
+## 1.11.0
+
+- Add the `arrayFlatten` boolean option to `dashdash.addOptionType` used for
+  custom option types. This allows one to create an `arrayOf...` option type
+  where each usage of the option can return multiple results. For example:
+
+        node mytool.js --foo a,b --foo c
+
+  We could define an option type for `--foo` such that
+  `opts.foo = ['a', 'b', 'c']`. See
+  "[examples/custom-option-arrayOfCommaSepString.js](examples/custom-option-arrayOfCommaSepString.js)"
+  for an example.
+
+
+## 1.10.1
+
+- Trim the published package to the minimal bits. Before: 24K tarball, 144K unpacked.
+  After: 12K tarball, 48K unpacked. `npm` won't let me drop the README.md. :)
+
+
+## 1.10.0
+
+- [issue #9] Support `includeDefault` in help config (similar to `includeEnv`) to have a
+  note of an option's default value, if any, in help output.
+- [issue #11] Fix option group breakage introduced in v1.9.0.
+
+
+## 1.9.0
+
+- [issue #10] Custom option types added with `addOptionType` can specify a
+  "default" value. See "examples/custom-option-fruit.js".
+
+
+## 1.8.0
+
+- Support `hidden: true` in an option spec to have help output exclude this
+  option.
+
+
+## 1.7.3
+
+- [issue #8] Fix parsing of a short option group when one of the
+  option takes an argument. For example, consider `tail` with
+  a `-f` boolean option and a `-n` option that takes a number
+  argument. This should parse:
+
+        tail -fn5
+
+  Before this change, that would not parse correctly.
+  It is suspected that this was introduced in version 1.4.0
+  (with commit 656fa8bc71c372ebddad0a7026bd71611e2ec99a).
+
+
+## 1.7.2
+
+- Known issues: #8
+
+- Exclude 'tools/' dir in packages published to npm.
+
+
+## 1.7.1
+
+- Known issues: #8
+
+- Support an option group *empty string* value:
+
+        ...
+        { group: '' },
+        ...
+
+  to render as a blank line in option help. This can help separate loosely
+  related sets of options without resorting to a title for option groups.
+
+
+## 1.7.0
+
+- Known issues: #8
+
+- [pull #7] Support for `<parser>.help({helpWrap: false, ...})` option to be able
+  to fully control the formatting for option help (by Patrick Mooney) `helpWrap:
+  false` can also be set on individual options in the option objects, e.g.:
+
+        var options = [
+            {
+              names: ['foo'],
+              type: 'string',
+              helpWrap: false,
+              help: 'long help with\n  newlines' +
+                '\n  spaces\n  and such\nwill render correctly'
+            },
+            ...
+        ];
+
+
+## 1.6.0
+
+- Known issues: #8
+
+- [pull #6] Support headings between groups of options (by Joshua M. Clulow)
+  so that this code:
+
+        var options = [
+            { group: 'Armament Options' },
+            { names: [ 'weapon', 'w' ], type: 'string' },
+            { group: 'General Options' },
+            { names: [ 'help', 'h' ], type: 'bool' }
+        ];
+        ...
+
+  will give you this help output:
+
+        ...
+          Armament Options:
+            -w, --weapon
+
+          General Options:
+            -h, --help
+        ...
+
+
+## 1.5.0
+
+- Known issues: #8
+
+- Add support for adding custom option types. "examples/custom-option-duration.js"
+  shows an example adding a "duration" option type.
+
+        $ node custom-option-duration.js -t 1h
+        duration: 3600000 ms
+        $ node custom-option-duration.js -t 1s
+        duration: 1000 ms
+        $ node custom-option-duration.js -t 5d
+        duration: 432000000 ms
+        $ node custom-option-duration.js -t bogus
+        custom-option-duration.js: error: arg for "-t" is not a valid duration: "bogus"
+
+  A custom option type is added via:
+
+        var dashdash = require('dashdash');
+        dashdash.addOptionType({
+            name: '...',
+            takesArg: true,
+            helpArg: '...',
+            parseArg: function (option, optstr, arg) {
+                ...
+            }
+        });
+
+- [issue #4] Add `date` and `arrayOfDate` option types. They accept these date
+  formats: epoch second times (e.g. 1396031701) and ISO 8601 format:
+  `YYYY-MM-DD[THH:MM:SS[.sss][Z]]` (e.g. "2014-03-28",
+  "2014-03-28T18:35:01.489Z"). See "examples/date.js" for an example usage.
+
+        $ node examples/date.js -s 2014-01-01 -e $(date +%s)
+        start at 2014-01-01T00:00:00.000Z
+        end at 2014-03-29T04:26:18.000Z
+
+
+## 1.4.0
+
+- Known issues: #8
+
+- [pull #2, pull #3] Add a `allowUnknown: true` option on `createParser` to
+  allow unknown options to be passed through as `opts._args` instead of parsing
+  throwing an exception (by https://github.com/isaacs).
+
+  See 'allowUnknown' in the README for a subtle caveat.
+
+
+## 1.3.2
+
+- Fix a subtlety where a *bool* option using both `env` and `default` didn't
+  work exactly correctly. If `default: false` then all was fine (by luck).
+  However, if you had an option like this:
+
+        options: [ {
+            names: ['verbose', 'v'],
+            env: 'FOO_VERBOSE',
+            'default': true,    // <--- this
+            type: 'bool'
+        } ],
+
+  wanted `FOO_VERBOSE=0` to make the option false, then you need the fix
+  in this version of dashdash.
+
+
+## 1.3.1
+
+- [issue #1] Fix an envvar not winning over an option 'default'. Previously
+  an option with both `default` and `env` would never take a value from the
+  environment variable. E.g. `FOO_FILE` would never work here:
+
+        options: [ {
+            names: ['file', 'f'],
+            env: 'FOO_FILE',
+            'default': 'default.file',
+            type: 'string'
+        } ],
+
+
+## 1.3.0
+
+- [Backward incompatible change for boolean envvars] Change the
+  interpretation of environment variables for boolean options to consider '0'
+  to be false. Previous to this *any* value to the envvar was considered
+  true -- which was quite misleading. Example:
+
+        $ FOO_VERBOSE=0 node examples/foo.js
+        # opts: { verbose: [ false ],
+          _order: [ { key: 'verbose', value: false, from: 'env' } ],
+          _args: [] }
+        # args: []
+
+
+## 1.2.1
+
+- Fix for `parse.help({includeEnv: true, ...})` handling to ensure that an
+  option with an `env` **but no `help`** still has the "Environment: ..."
+  output. E.g.:
+
+        { names: ['foo'], type: 'string', env: 'FOO' }
+
+        ...
+
+        --foo=ARG      Environment: FOO=ARG
+
+
+## 1.2.0
+
+- Transform the option key on the `opts` object returned from
+  `<parser>.parse()` for convenience. Currently this is just
+  `s/-/_/g`, e.g. '--dry-run' -> `opts.dry_run`. This allow one to use hyphen
+  in option names (common) but not have to do silly things like
+  `opt["dry-run"]` to access the parsed results.
+
+
+## 1.1.0
+
+- Environment variable integration. Envvars can be associated with an option,
+  then option processing will fallback to using that envvar if defined and
+  if the option isn't specified in argv. See the "Environment variable
+  integration" section in the README.
+
+- Change the `<parser>.parse()` signature to take a single object with keys
+  for arguments. The old signature is still supported.
+
+- `dashdash.createParser(CONFIG)` alternative to `new dashdash.Parser(CONFIG)`
+  a la many node-land APIs.
+
+
+## 1.0.2
+
+- Add "positiveInteger" and "arrayOfPositiveInteger" option types that only
+  accept positive integers.
+
+- Add "integer" and "arrayOfInteger" option types that accepts only integers.
+  Note that, for better or worse, these do NOT accept: "0x42" (hex), "1e2"
+  (with exponent) or "1.", "3.0" (floats).
+
+
+## 1.0.1
+
+- Fix not modifying the given option spec objects (which breaks creating
+  a Parser with them more than once).
+
+
+## 1.0.0
+
+First release.

+A light, featureful and explicit option parsing library for node.js.
+
+[Why another one? See below](#why). tl;dr: The others I've tried are one of
+too loosey goosey (not explicit), too big/too many deps, or ill specified.

+
+Follow <a href="https://twitter.com/intent/user?screen_name=trentmick" target="_blank">@trentmick</a>
+for updates to node-dashdash.
+
+# Install
+
+    npm install dashdash
+
+
+# Usage
+
+```javascript
+var dashdash = require('dashdash');
+
+// Specify the options. Minimally `name` (or `names`) and `type`
+// must be given for each.
+var options = [
+    {
+        // `names` or a single `name`. First element is the `opts.KEY`.
+        names: ['help', 'h'],
+        // See "Option specs" below for types.
+        type: 'bool',
+        help: 'Print this help and exit.'
+    }
+];
+
+// Shortcut form. As called it infers `process.argv`. See below for
+// the longer form to use methods like `.help()` on the Parser object.
+var opts = dashdash.parse({options: options});
+
+console.log("opts:", opts);
+console.log("args:", opts._args);
+```
+
+
+# Longer Example
+
+A more realistic [starter script "foo.js"](./examples/foo.js) is as follows.
+This also shows using `parser.help()` for formatted option help.
+
+```javascript
+var dashdash = require('./lib/dashdash');
+
+var options = [
+    {
+        name: 'version',
+        type: 'bool',
+        help: 'Print tool version and exit.'
+    },
+    {
+        names: ['help', 'h'],
+        type: 'bool',
+        help: 'Print this help and exit.'
+    },
+    {
+        names: ['verbose', 'v'],
+        type: 'arrayOfBool',
+        help: 'Verbose output. Use multiple times for more verbose.'
+    },
+    {
+        names: ['file', 'f'],
+        type: 'string',
+        help: 'File to process',
+        helpArg: 'FILE'
+    }
+];
+
+var parser = dashdash.createParser({options: options});
+try {
+    var opts = parser.parse(process.argv);
+} catch (e) {
+    console.error('foo: error: %s', e.message);
+    process.exit(1);
+}
+
+console.log("# opts:", opts);
+console.log("# args:", opts._args);
+
+// Use `parser.help()` for formatted options help.
+if (opts.help) {
+    var help = parser.help({includeEnv: true}).trimRight();
+    console.log('usage: node foo.js [OPTIONS]\n'
+                + 'options:\n'
+                + help);
+    process.exit(0);
+}
+
+// ...
+```
+
+
+Some example output from this script (foo.js):
+
+```
+$ node foo.js -h
+# opts: { help: true,
+  _order: [ { name: 'help', value: true, from: 'argv' } ],
+  _args: [] }
+# args: []
+usage: node foo.js [OPTIONS]
+options:
+    --version             Print tool version and exit.
+    -h, --help            Print this help and exit.
+    -v, --verbose         Verbose output. Use multiple times for more verbose.
+    -f FILE, --file=FILE  File to process
+
+$ node foo.js -v
+# opts: { verbose: [ true ],
+  _order: [ { name: 'verbose', value: true, from: 'argv' } ],
+  _args: [] }
+# args: []
+
+$ node foo.js --version arg1
+# opts: { version: true,
+  _order: [ { name: 'version', value: true, from: 'argv' } ],
+  _args: [ 'arg1' ] }
+# args: [ 'arg1' ]
+
+$ node foo.js -f bar.txt
+# opts: { file: 'bar.txt',
+  _order: [ { name: 'file', value: 'bar.txt', from: 'argv' } ],
+  _args: [] }
+# args: []
+
+$ node foo.js -vvv --file=blah
+# opts: { verbose: [ true, true, true ],
+  file: 'blah',
+  _order:
+   [ { name: 'verbose', value: true, from: 'argv' },
+     { name: 'verbose', value: true, from: 'argv' },
+     { name: 'verbose', value: true, from: 'argv' },
+     { name: 'file', value: 'blah', from: 'argv' } ],
+  _args: [] }
+# args: []
+```
+
+
+See the ["examples"](examples/) dir for a number of starter examples using
+some of dashdash's features.
+
+
+# Environment variable integration
+
+If you want to allow environment variables to specify options to your tool,
+dashdash makes this easy. We can change the 'verbose' option in the example
+above to include an 'env' field:
+
+```javascript
+    {
+        names: ['verbose', 'v'],
+        type: 'arrayOfBool',
+        env: 'FOO_VERBOSE',         // <--- add this line
+        help: 'Verbose output. Use multiple times for more verbose.'
+    },
+```
+
+then the **"FOO_VERBOSE" environment variable** can be used to set this
+option:
+
+```shell
+$ FOO_VERBOSE=1 node foo.js
+# opts: { verbose: [ true ],
+  _order: [ { name: 'verbose', value: true, from: 'env' } ],
+  _args: [] }
+# args: []
+```
+
+Boolean options will interpret the empty string as unset, '0' as false
+and anything else as true.
+
+```shell
+$ FOO_VERBOSE= node examples/foo.js                 # not set
+# opts: { _order: [], _args: [] }
+# args: []
+
+$ FOO_VERBOSE=0 node examples/foo.js                # '0' is false
+# opts: { verbose: [ false ],
+  _order: [ { key: 'verbose', value: false, from: 'env' } ],
+  _args: [] }
+# args: []
+
+$ FOO_VERBOSE=1 node examples/foo.js                # true
+# opts: { verbose: [ true ],
+  _order: [ { key: 'verbose', value: true, from: 'env' } ],
+  _args: [] }
+# args: []
+
+$ FOO_VERBOSE=boogabooga node examples/foo.js       # true
+# opts: { verbose: [ true ],
+  _order: [ { key: 'verbose', value: true, from: 'env' } ],
+  _args: [] }
+# args: []
+```
+
+Non-booleans can be used as well. Strings:
+
+```shell
+$ FOO_FILE=data.txt node examples/foo.js
+# opts: { file: 'data.txt',
+  _order: [ { key: 'file', value: 'data.txt', from: 'env' } ],
+  _args: [] }
+# args: []
+```
+
+Numbers:
+
+```shell
+$ FOO_TIMEOUT=5000 node examples/foo.js
+# opts: { timeout: 5000,
+  _order: [ { key: 'timeout', value: 5000, from: 'env' } ],
+  _args: [] }
+# args: []
+
+$ FOO_TIMEOUT=blarg node examples/foo.js
+foo: error: arg for "FOO_TIMEOUT" is not a positive integer: "blarg"
+```
+
+With the `includeEnv: true` config to `parser.help()` the environment
+variable can also be included in **help output**:
+
+    usage: node foo.js [OPTIONS]
+    options:
+        --version             Print tool version and exit.
+        -h, --help            Print this help and exit.
+        -v, --verbose         Verbose output. Use multiple times for more verbose.
+                              Environment: FOO_VERBOSE=1
+        -f FILE, --file=FILE  File to process
+
+
+# Bash completion
+
+Dashdash provides a simple way to create a Bash completion file that you
+can place in your "bash_completion.d" directory -- sometimes that is
+"/usr/local/etc/bash_completion.d/"). Features:
+
+- Support for short and long opts
+- Support for knowing which options take arguments
+- Support for subcommands (e.g. 'git log <TAB>' to show just options for the
+  log subcommand). See
+  [node-cmdln](https://github.com/trentm/node-cmdln#bash-completion) for
+  how to integrate that.
+- Does the right thing with "--" to stop options.
+- Custom optarg and arg types for custom completions.
+
+Dashdash will return bash completion file content given a parser instance:
+
+    var parser = dashdash.createParser({options: options});
+    console.log( parser.bashCompletion({name: 'mycli'}) );
+
+or directly from a `options` array of options specs:
+
+    var code = dashdash.bashCompletionFromOptions({
+        name: 'mycli',
+        options: OPTIONS
+    });
+
+Write that content to "/usr/local/etc/bash_completion.d/mycli" and you will
+have Bash completions for `mycli`. Alternatively you can write it to
+any file (e.g. "~/.bashrc") and source it.
+
+You could add a `--completion` hidden option to your tool that emits the
+completion content and document for your users to call that to install
+Bash completions.
+
+See [examples/ddcompletion.js](examples/ddcompletion.js) for a complete
+example, including how one can define bash functions for completion of custom
+option types. Also see [node-cmdln](https://github.com/trentm/node-cmdln) for
+how it uses this for Bash completion for full multi-subcommand tools.

+
+# Parser config
+
+Parser construction (i.e. `dashdash.createParser(CONFIG)`) takes the
+following fields:
+
+- `options` (Array of option specs). Required. See the
+  [Option specs](#option-specs) section below.
+
+- `interspersed` (Boolean). Optional. Default is true. If true this allows
+  interspersed arguments and options. I.e.:
+
+        node ./tool.js -v arg1 arg2 -h   # '-h' is after interspersed args
+
+  Set it to false to have '-h' **not** get parsed as an option in the above
+  example.
+
+- `allowUnknown` (Boolean).  Optional.  Default is false.  If false, this causes
+  unknown arguments to throw an error.  I.e.:
+
+        node ./tool.js -v arg1 --afe8asefksjefhas
+
+  Set it to true to treat the unknown option as a positional
+  argument.
+
+  **Caveat**: When a shortopt group, such as `-xaz` contains a mix of
+  known and unknown options, the *entire* group is passed through
+  unmolested as a positional argument.
+
+  Consider if you have a known short option `-a`, and parse the
+  following command line:
+
+        node ./tool.js -xaz
+
+  where `-x` and `-z` are unknown.  There are multiple ways to
+  interpret this:
+
+    1. `-x` takes a value: `{x: 'az'}`
+    2. `-x` and `-z` are both booleans: `{x:true,a:true,z:true}`
+
+  Since dashdash does not know what `-x` and `-z` are, it can't know
+  if you'd prefer to receive `{a:true,_args:['-x','-z']}` or
+  `{x:'az'}`, or `{_args:['-xaz']}`. Leaving the positional arg unprocessed
+  is the easiest mistake for the user to recover from.
+
+
+# Option specs
+
+Example using all fields (required fields are noted):
+
+```javascript
+{
+    names: ['file', 'f'],       // Required (one of `names` or `name`).
+    type: 'string',             // Required.
+    completionType: 'filename',
+    env: 'MYTOOL_FILE',
+    help: 'Config file to load before running "mytool"',
+    helpArg: 'PATH',
+    helpWrap: false,
+    default: path.resolve(process.env.HOME, '.mytoolrc')
+}
+```
+
+Each option spec in the `options` array must/can have the following fields:
+
+- `name` (String) or `names` (Array). Required. These give the option name
+  and aliases. The first name (if more than one given) is the key for the
+  parsed `opts` object.
+
+- `type` (String). Required. One of:
+
+    - bool
+    - string
+    - number
+    - integer
+    - positiveInteger
+    - date (epoch seconds, e.g. 1396031701, or ISO 8601 format
+      `YYYY-MM-DD[THH:MM:SS[.sss][Z]]`, e.g. "2014-03-28T18:35:01.489Z")
+    - arrayOfBool
+    - arrayOfString
+    - arrayOfNumber
+    - arrayOfInteger
+    - arrayOfPositiveInteger
+    - arrayOfDate
+
+  FWIW, these names attempt to match with asserts on
+  [assert-plus](https://github.com/mcavage/node-assert-plus).
+  You can add your own custom option types with `dashdash.addOptionType`.
+  See below.
+
+- `completionType` (String). Optional. This is used for [Bash
+  completion](#bash-completion) for an option argument. If not specified,
+  then the value of `type` is used. Any string may be specified, but only the
+  following values have meaning:
+
+    - `none`: Provide no completions.
+    - `file`: Bash's default completion (i.e. `complete -o default`), which
+      includes filenames.
+    - *Any string FOO for which a `function complete_FOO` Bash function is
+      defined.* This is for custom completions for a given tool. Typically
+      these custom functions are provided in the `specExtra` argument to
+      `dashdash.bashCompletionFromOptions()`. See
+      ["examples/ddcompletion.js"](examples/ddcompletion.js) for an example.
+
+- `env` (String or Array of String). Optional. An environment variable name
+  (or names) that can be used as a fallback for this option. For example,
+  given a "foo.js" like this:
+
+        var options = [{names: ['dry-run', 'n'], env: 'FOO_DRY_RUN'}];
+        var opts = dashdash.parse({options: options});
+
+  Both `node foo.js --dry-run` and `FOO_DRY_RUN=1 node foo.js` would result
+  in `opts.dry_run = true`.
+
+  An environment variable is only used as a fallback, i.e. it is ignored if
+  the associated option is given in `argv`.
+
+- `help` (String). Optional. Used for `parser.help()` output.
+
+- `helpArg` (String). Optional. Used in help output as the placeholder for
+  the option argument, e.g. the "PATH" in:
+
+        ...
+        -f PATH, --file=PATH    File to process
+        ...
+
+- `helpWrap` (Boolean). Optional, default true. Set this to `false` to have
+  that option's `help` *not* be text wrapped in `<parser>.help()` output.
+
+- `default`. Optional. A default value used for this option, if the
+  option isn't specified in argv.
+
+- `hidden` (Boolean). Optional, default false. If true, help output will not
+  include this option. See also the `includeHidden` option to
+  `bashCompletionFromOptions()` for [Bash completion](#bash-completion).
+
+
+# Option group headings
+
+You can add headings between option specs in the `options` array.  To do so,
+simply add an object with only a `group` property -- the string to print as
+the heading for the subsequent options in the array.  For example:
+
+```javascript
+var options = [
+    {
+        group: 'Armament Options'
+    },
+    {
+        names: [ 'weapon', 'w' ],
+        type: 'string'
+    },
+    {
+        group: 'General Options'
+    },
+    {
+        names: [ 'help', 'h' ],
+        type: 'bool'
+    }
+];
+...
+```
+
+Note: You can use an empty string, `{group: ''}`, to get a blank line in help
+output between groups of options.
+
+
+# Help config
+
+The `parser.help(...)` function is configurable as follows:
+
+        Options:
+          Armament Options:
+        ^^  -w WEAPON, --weapon=WEAPON  Weapon with which to crush. One of: |
+       /                                sword, spear, maul                  |
+      /   General Options:                                                  |
+     /      -h, --help                  Print this help and exit.           |
+    /   ^^^^                            ^                                   |
+    \       `-- indent                   `-- helpCol              maxCol ---'
+     `-- headingIndent
+
+- `indent` (Number or String). Default 4. Set to a number (for that many
+  spaces) or a string for the literal indent.
+- `headingIndent` (Number or String). Default half length of `indent`. Set to
+  a number (for that many spaces) or a string for the literal indent. This
+  indent applies to group heading lines, between normal option lines.
+- `nameSort` (String). Default is 'length'. By default the names are
+  sorted to put the short opts first (i.e. '-h, --help' preferred
+  to '--help, -h'). Set to 'none' to not do this sorting.
+- `maxCol` (Number). Default 80. Note that reflow is just done on whitespace
+  so a long token in the option help can overflow maxCol.
+- `helpCol` (Number). If not set a reasonable value will be determined
+  between `minHelpCol` and `maxHelpCol`.
+- `minHelpCol` (Number). Default 20.
+- `maxHelpCol` (Number). Default 40.
+- `helpWrap` (Boolean). Default true. Set to `false` to have option `help`
+  strings *not* be textwrapped to the helpCol..maxCol range.
+- `includeEnv` (Boolean). Default false. If the option has associated
+  environment variables (via the `env` option spec attribute), then
+  append mentioned of those envvars to the help string.
+- `includeDefault` (Boolean). Default false. If the option has a default value
+  (via the `default` option spec attribute, or a default on the option's type),
+  then a "Default: VALUE" string will be appended to the help string.
+
+
+# Custom option types
+
+Dashdash includes a good starter set of option types that it will parse for
+you. However, you can add your own via:
+
+    var dashdash = require('dashdash');
+    dashdash.addOptionType({
+        name: '...',
+        takesArg: true,
+        helpArg: '...',
+        parseArg: function (option, optstr, arg) {
+            ...
+        },
+        array: false,  // optional
+        arrayFlatten: false,  // optional
+        default: ...,   // optional
+        completionType: ...  // optional
+    });
+
+For example, a simple option type that accepts 'yes', 'y', 'no' or 'n' as
+a boolean argument would look like:
+
+    var dashdash = require('dashdash');
+
+    function parseYesNo(option, optstr, arg) {
+        var argLower = arg.toLowerCase()
+        if (~['yes', 'y'].indexOf(argLower)) {
+            return true;
+        } else if (~['no', 'n'].indexOf(argLower)) {
+            return false;
+        } else {
+            throw new Error(format(
+                'arg for "%s" is not "yes" or "no": "%s"',
+                optstr, arg));
+        }
+    }
+
+    dashdash.addOptionType({
+        name: 'yesno'
+        takesArg: true,
+        helpArg: '<yes|no>',
+        parseArg: parseYesNo
+    });
+
+    var options = {
+        {names: ['answer', 'a'], type: 'yesno'}
+    };
+    var opts = dashdash.parse({options: options});
+
+See "examples/custom-option-\*.js" for other examples.
+See the `addOptionType` block comment in "lib/dashdash.js" for more details.
+Please let me know [with an
+issue](https://github.com/trentm/node-dashdash/issues/new) if you write a
+generally useful one.
+
+
+
+# Why
+
+Why another node.js option parsing lib?
+
+- `nopt` really is just for "tools like npm". Implicit opts (e.g. '--no-foo'
+  works for every '--foo'). Can't disable abbreviated opts. Can't do multiple
+  usages of same opt, e.g. '-vvv' (I think). Can't do grouped short opts.
+
+- `optimist` has surprise interpretation of options (at least to me).
+  Implicit opts mean ambiguities and poor error handling for fat-fingering.
+  `process.exit` calls makes it hard to use as a libary.
+
+- `optparse` Incomplete docs. Is this an attempted clone of Python's `optparse`.
+  Not clear. Some divergence. `parser.on("name", ...)` API is weird.
+
+- `argparse` Dep on underscore. No thanks just for option processing.
+  `find lib | wc -l` -> `26`. Overkill.
+  Argparse is a bit different anyway. Not sure I want that.
+
+- `posix-getopt` No type validation. Though that isn't a killer. AFAIK can't
+  have a long opt without a short alias. I.e. no `getopt_long` semantics.
+  Also, no whizbang features like generated help output.
+
+- ["commander.js"](https://github.com/visionmedia/commander.js): I wrote
+  [a critique](http://trentm.com/2014/01/a-critique-of-commander-for-nodejs.html)
+  a while back. It seems fine, but last I checked had
+  [an outstanding bug](https://github.com/visionmedia/commander.js/pull/121)
+  that would prevent me from using it.

+# A generic Bash completion driver script.
+#
+# This is meant to provide a re-usable chunk of Bash to use for
+# "etc/bash_completion.d/" files for individual tools. Only the "Configuration"
+# section with tool-specific info need differ. Features:
+#
+# - support for short and long opts
+# - support for knowing which options take arguments
+# - support for subcommands (e.g. 'git log <TAB>' to show just options for the
+#   log subcommand)
+# - does the right thing with "--" to stop options
+# - custom optarg and arg types for custom completions
+# - (TODO) support for shells other than Bash (tcsh, zsh, fish?, etc.)
+#
+#
+# Examples/design:
+#
+# 1. Bash "default" completion. By default Bash's 'complete -o default' is
+#    enabled. That means when there are no completions (e.g. if no opts match
+#    the current word), then you'll get Bash's default completion. Most notably
+#    that means you get filename completion. E.g.:
+#       $ tool ./<TAB>
+#       $ tool READ<TAB>
+#
+# 2. all opts and subcmds:
+#       $ tool <TAB>
+#       $ tool -v <TAB>     # assuming '-v' doesn't take an arg
+#       $ tool -<TAB>       # matching opts
+#       $ git lo<TAB>       # matching subcmds
+#
+#    Long opt completions are given *without* the '=', i.e. we prefer space
+#    separated because that's easier for good completions.
+#
+# 3. long opt arg with '='
+#       $ tool --file=<TAB>
+#       $ tool --file=./d<TAB>
+#    We maintain the "--file=" prefix. Limitation: With the attached prefix
+#    the 'complete -o filenames' doesn't know to do dirname '/' suffixing. Meh.
+#
+# 4. envvars:
+#       $ tool $<TAB>
+#       $ tool $P<TAB>
+#    Limitation: Currently only getting exported vars, so we miss "PS1" and
+#    others.
+#
+# 5. Defer to other completion in a subshell:
+#       $ tool --file $(cat ./<TAB>
+#    We get this from 'complete -o default ...'.
+#
+# 6. Custom completion types from a provided bash function.
+#       $ tool --profile <TAB>        # complete available "profiles"
