PACKAGE.JSON(5) File Formats Manual PACKAGE.JSON(5)
NAME
package.json
Description
This document is all you need to know about what's required in your
package.json file. It must be actual JSON, not just a JavaScript ob-
ject
literal.
A lot of the behavior described in this document is affected by the
config
settings described in config.
name
If you plan to publish your package, the most important things in your
package.json are the name and version fields as they will be required.
The
name and version together form an identifier that is assumed to be
completely unique. Changes to the package should come along with
changes
to the version. If you don't plan to publish your package, the name and
version fields are optional.
The name is what your thing is called.
Some rules:
• The name must be less than or equal to 214 characters. This includes
the
scope for scoped packages.
• The names of scoped packages can begin with a dot or an underscore.
This
is not permitted without a scope.
• New packages must not have uppercase letters in the name.
• The name ends up being part of a URL, an argument on the command
line,
and a folder name. Therefore, the name can't contain any
non-URL-safe
characters.
Some tips:
• Don't use the same name as a core Node module.
• Don't put "js" or "node" in the name. It's assumed that it's js,
since
you're writing a package.json file, and you can specify the engine
using
the "engines" field. (See below.)
• The name will probably be passed as an argument to require(), so it
should be something short, but also reasonably descriptive.
• You may want to check the npm registry to see if there's something
by
that name already, before you get too attached to it.
https://www.npmjs.com/
A name can be optionally prefixed by a scope, e.g. @myorg/mypackage.
See
scope for more detail.
version
If you plan to publish your package, the most important things in your
package.json are the name and version fields as they will be required.
The
name and version together form an identifier that is assumed to be
completely unique. Changes to the package should come along with
changes
to the version. If you don't plan to publish your package, the name and
version fields are optional.
Version must be parseable by
node-semver, which is bundled with
npm as a dependency. (npm install semver to use it yourself.)
description
Put a description in it. It's a string. This helps people discover
your
package, as it's listed in npm search.
keywords
Put keywords in it. It's an array of strings. This helps people dis-
cover
your package as it's listed in npm search.
homepage
The url to the project homepage.
Example:
"homepage": "https://github.com/owner/project#readme"
bugs
The url to your project's issue tracker and / or the email address to
which
issues should be reported. These are helpful for people who encounter
issues with your package.
It should look like this:
{
"url" : "https://github.com/owner/project/issues",
"email" : "project@hostname.com"
}
You can specify either one or both values. If you want to provide only
a
url, you can specify the value for "bugs" as a simple string instead of
an
object.
If a url is provided, it will be used by the npm bugs command.
license
You should specify a license for your package so that people know how
they
are permitted to use it, and any restrictions you're placing on it.
If you're using a common license such as BSD-2-Clause or MIT, add a
current
SPDX license identifier for the license you're using, like this:
{
"license" : "BSD-3-Clause"
}
You can check the full list of SPDX license
IDs. Ideally you should pick one that is
OSI approved.
If your package is licensed under multiple common licenses, use an SPDX
license expression syntax version 2.0
string, like this:
{
"license" : "(ISC OR GPL-3.0)"
}
If you are using a license that hasn't been assigned an SPDX identi-
fier, or if
you are using a custom license, use a string value like this one:
{
"license" : "SEE LICENSE IN <filename>"
}
Then include a file named <filename> at the top level of the package.
Some old packages used license objects or a "licenses" property con-
taining
an array of license objects:
// Not valid metadata
{
"license" : {
"type" : "ISC",
"url" : "https://opensource.org/licenses/ISC"
}
}
// Not valid metadata
{
"licenses" : [
{
"type": "MIT",
"url": "https://www.opensource.org/licenses/mit-license.php"
},
{
"type": "Apache-2.0",
"url": "https://opensource.org/licenses/apache2.0.php"
}
]
}
Those styles are now deprecated. Instead, use SPDX expressions, like
this:
{
"license": "ISC"
}
{
"license": "(MIT OR Apache-2.0)"
}
Finally, if you do not wish to grant others the right to use a private
or
unpublished package under any terms:
{
"license": "UNLICENSED"
}
Consider also setting "private": true to prevent accidental
publication.
people fields: author, contributors
The "author" is one person. "contributors" is an array of people. A
"person" is an object with a "name" field and optionally "url" and
"email",
like this:
{
"name" : "Barney Rubble",
"email" : "b@rubble.com",
"url" : "http://barnyrubble.tumblr.com/"
}
Or you can shorten that all into a single string, and npm will parse it
for
you:
{
"author": "Barney Rubble <b@rubble.com> (http://barnyrubble.tumblr.com/)"
}
Both email and url are optional either way.
npm also sets a top-level "maintainers" field with your npm user info.
funding
You can specify an object containing a URL that provides up-to-date
information about ways to help fund development of your package, or a
string URL, or an array of these:
{
"funding": {
"type" : "individual",
"url" : "http://example.com/donate"
},
"funding": {
"type" : "patreon",
"url" : "https://www.patreon.com/my-account"
},
"funding": "http://example.com/donate",
"funding": [
{
"type" : "individual",
"url" : "http://example.com/donate"
},
"http://example.com/donateAlso",
{
"type" : "patreon",
"url" : "https://www.patreon.com/my-account"
}
]
}
Users can use the npm fund subcommand to list the funding URLs of all
dependencies of their project, direct and indirect. A shortcut to visit
each funding url is also available when providing the project name such
as:
npm fund <projectname> (when there are multiple URLs, the first one
will
be visited)
files
The optional files field is an array of file patterns that describes
the
entries to be included when your package is installed as a dependency.
File
patterns follow a similar syntax to .gitignore, but reversed: including
a
file, directory, or glob pattern (*, **/*, and such) will make it so
that file is included in the tarball when it's packed. Omitting the
field
will make it default to ["*"], which means it will include
all files.
Some special files and directories are also included or excluded re-
gardless
of whether they exist in the files array (see below).
You can also provide a .npmignore file in the root of your package or
in
subdirectories, which will keep files from being included. At the root
of
your package it will not override the "files" field, but in subdirecto-
ries
it will. The .npmignore file works just like a .gitignore. If there is
a .gitignore file, and .npmignore is missing, .gitignore's contents
will be used instead.
Files included with the "package.json#files" field cannot be excluded
through .npmignore or .gitignore.
Certain files are always included, regardless of settings:
• package.json
• README
• LICENSE / LICENCE
• The file in the "main" field
README & LICENSE can have any case and extension.
Conversely, some files are always ignored:
• .git
• CVS
• .svn
• .hg
• .lock-wscript
• .wafpickle-N
• .*.swp
• .DS_Store
• ._*
• npm-debug.log
• .npmrc
• node_modules
• config.gypi
• *.orig
• package-lock.json (use
npm-shrinkwrap.json if you wish
it to be published)
main
The main field is a module ID that is the primary entry point to your
program. That is, if your package is named foo, and a user installs
it,
and then does require("foo"), then your main module's exports
object will
be returned.
This should be a module relative to the root of your package folder.
For most modules, it makes the most sense to have a main script and of-
ten
not much else.
If main is not set it defaults to index.js in the package's root
folder.
browser
If your module is meant to be used client-side the browser field should
be
used instead of the main field. This is helpful to hint users that it
might
rely on primitives that aren't available in Node.js modules. (e.g.
window)
bin
A lot of packages have one or more executable files that they'd like to
install into the PATH. npm makes this pretty easy (in fact, it uses
this
feature to install the "npm" executable.)
To use this, supply a bin field in your package.json which is a map of
command name to local file name. When this package is installed glob-
ally,
that file will be either linked inside the global bins directory or
a cmd (Windows Command File) will be created which executes the speci-
fied
file in the bin field, so it is available to run by name or name.cmd
(on
Windows PowerShell). When this package is installed as a dependency in
another
package, the file will be linked where it will be available to that
package
either directly by npm exec or by name in other scripts when invoking
them
via npm run-script.
For example, myapp could have this:
{
"bin": {
"myapp": "./cli.js"
}
}
So, when you install myapp, in case of unix-like OS it'll create a sym-
link
from the cli.js script to /usr/local/bin/myapp and in case of windows
it
will create a cmd file usually at C:\Users\{Username}\AppData\Roam-
ing\npm\myapp.cmd
which runs the cli.js script.
If you have a single executable, and its name should be the name of the
package, then you can just supply it as a string. For example:
{
"name": "my-program",
"version": "1.2.5",
"bin": "./path/to/program"
}
would be the same as this:
{
"name": "my-program",
"version": "1.2.5",
"bin": {
"my-program": "./path/to/program"
}
}
Please make sure that your file(s) referenced in bin starts with
#!/usr/bin/env node, otherwise the scripts are started without the node
executable!
Note that you can also set the executable files using directories.bin
See folders for more info on
executables.
man
Specify either a single file or an array of filenames to put in place
for
the man program to find.
If only a single file is provided, then it's installed such that it is
the
result from man <pkgname>, regardless of its actual filename. For
example:
{
"name": "foo",
"version": "1.2.3",
"description": "A packaged foo fooer for fooing foos",
"main": "foo.js",
"man": "./man/doc.1"
}
would link the ./man/doc.1 file in such that it is the target for man
foo
If the filename doesn't start with the package name, then it's pre-
fixed.
So, this:
{
"name": "foo",
"version": "1.2.3",
"description": "A packaged foo fooer for fooing foos",
"main": "foo.js",
"man": [
"./man/foo.1",
"./man/bar.1"
]
}
will create files to do man foo and man foo-bar.
Man files must end with a number, and optionally a .gz suffix if they
are
compressed. The number dictates which man section the file is in-
stalled
into.
{
"name": "foo",
"version": "1.2.3",
"description": "A packaged foo fooer for fooing foos",
"main": "foo.js",
"man": [
"./man/foo.1",
"./man/foo.2"
]
}
will create entries for man foo and man 2 foo
directories
The CommonJS Packages spec
details a few ways that you can indicate the structure of your package
using a directories object. If you look at npm's
package.json, you'll see that it
has directories for doc, lib, and man.
In the future, this information may be used in other creative ways.
directories.bin
If you specify a bin directory in directories.bin, all the files in
that folder will be added.
Because of the way the bin directive works, specifying both a bin path
and setting directories.bin is an error. If you want to specify
individual files, use bin, and for all the files in an existing bin
directory, use directories.bin.
directories.man
A folder that is full of man pages. Sugar to generate a "man" array by
walking the folder.
repository
Specify the place where your code lives. This is helpful for people who
want to contribute. If the git repo is on GitHub, then the npm docs
command will be able to find you.
Do it like this:
{
"repository": {
"type": "git",
"url": "https://github.com/npm/cli.git"
}
}
The URL should be a publicly available (perhaps read-only) url that can
be
handed directly to a VCS program without any modification. It should
not
be a url to an html project page that you put in your browser. It's
for
computers.
For GitHub, GitHub gist, Bitbucket, or GitLab repositories you can use
the
same shortcut syntax you use for npm install:
{
"repository": "npm/npm",
"repository": "github:user/repo",
"repository": "gist:11081aaa281",
"repository": "bitbucket:user/repo",
"repository": "gitlab:user/repo"
}
If the package.json for your package is not in the root directory (for
example if it is part of a monorepo), you can specify the directory in
which it lives:
{
"repository": {
"type": "git",
"url": "https://github.com/facebook/react.git",
"directory": "packages/react-dom"
}
}
scripts
The "scripts" property is a dictionary containing script commands that
are
run at various times in the lifecycle of your package. The key is the
lifecycle event, and the value is the command to run at that point.
See scripts to find out more about writing package
scripts.
config
A "config" object can be used to set configuration parameters used in
package scripts that persist across upgrades. For instance, if a pack-
age
had the following:
{
"name": "foo",
"config": {
"port": "8080"
}
}
It could also have a "start" command that referenced the
npm_package_config_port environment variable.
dependencies
Dependencies are specified in a simple object that maps a package name
to a
version range. The version range is a string which has one or more
space-separated descriptors. Dependencies can also be identified with
a
tarball or git URL.
Please do not put test harnesses or transpilers or other "development"
time tools in your dependencies object. See devDependencies, below.
See semver for more details about specifying version ranges.
• version Must match version exactly
• >version Must be greater than version
• >=version etc
• <version
• <=version
• ~version "Approximately equivalent to version" See
semver
• ^version "Compatible with version" See semver
• 1.2.x 1.2.0, 1.2.1, etc., but not 1.3.0
• http://... See 'URLs as Dependencies' below
• * Matches any version
• "" (just an empty string) Same as *
• version1 - version2 Same as >=version1 <=version2.
• range1 || range2 Passes if either range1 or range2 are satisfied.
• git... See 'Git URLs as Dependencies' below
• user/repo See 'GitHub URLs' below
• tag A specific version tagged and published as tag See npm dist-tag
• path/path/path See Local Paths below
For example, these are all valid:
{
"dependencies": {
"foo": "1.0.0 - 2.9999.9999",
"bar": ">=1.0.2 <2.1.2",
"baz": ">1.0.2 <=2.3.4",
"boo": "2.0.1",
"qux": "<1.0.0 || >=2.3.1 <2.4.5 || >=2.5.2 <3.0.0",
"asd": "http://asdf.com/asdf.tar.gz",
"til": "~1.2",
"elf": "~1.2.3",
"two": "2.x",
"thr": "3.3.x",
"lat": "latest",
"dyl": "file:../dyl"
}
}
URLs as Dependencies
You may specify a tarball URL in place of a version range.
This tarball will be downloaded and installed locally to your package
at
install time.
Git URLs as Dependencies
Git urls are of the form:
<protocol>://[<user>[:<password>]@]<hostname>[:<port>][:][/]<path>[#<commit-ish> | #semver:<semver>]
<protocol> is one of git, git+ssh, git+http, git+https, or
git+file.
If #<commit-ish> is provided, it will be used to clone exactly that
commit. If the commit-ish has the format #semver:<semver>, <semver> can
be any valid semver range or exact version, and npm will look for any
tags
or refs matching that range in the remote repository, much as it would
for
a registry dependency. If neither #<commit-ish> or #semver:<semver> is
specified, then the default branch is used.
Examples:
git+ssh://git@github.com:npm/cli.git#v1.0.27
git+ssh://git@github.com:npm/cli#semver:^5.0
git+https://isaacs@github.com/npm/cli.git
git://github.com/npm/cli.git#v1.0.27
When installing from a git repository, the presence of certain fields
in the
package.json will cause npm to believe it needs to perform a build. To
do so
your repository will be cloned into a temporary directory, all of its
deps
installed, relevant scripts run, and the resulting directory packed and
installed.
This flow will occur if your git dependency uses workspaces, or if any
of the
following scripts are present:
• build
• prepare
• prepack
• preinstall
• install
• postinstall
If your git repository includes pre-built artifacts, you will likely
want to
make sure that none of the above scripts are defined, or your depen-
dency
will be rebuilt for every installation.
GitHub URLs
As of version 1.1.65, you can refer to GitHub urls as just "foo":
"user/foo-project". Just as with git URLs, a commit-ish suffix can be
included. For example:
{
"name": "foo",
"version": "0.0.0",
"dependencies": {
"express": "expressjs/express",
"mocha": "mochajs/mocha#4727d357ea",
"module": "user/repo#feature\/branch"
}
}
Local Paths
As of version 2.0.0 you can provide a path to a local directory that
contains a package. Local paths can be saved using npm install -S or
npm install --save, using any of these forms:
../foo/bar
~/foo/bar
./foo/bar
/foo/bar
in which case they will be normalized to a relative path and added to
your
package.json. For example:
{
"name": "baz",
"dependencies": {
"bar": "file:../foo/bar"
}
}
This feature is helpful for local offline development and creating
tests
that require npm installing where you don't want to hit an external
server,
but should not be used when publishing packages to the public registry.
note: Packages linked by local path will not have their own
dependencies installed when npm install is ran in this case. You must
run npm install from inside the local path itself.
devDependencies
If someone is planning on downloading and using your module in their
program, then they probably don't want or need to download and build
the
external test or documentation framework that you use.
In this case, it's best to map these additional items in a
devDependencies object.
These things will be installed when doing npm link or npm install from
the root of a package, and can be managed like any other npm configura-
tion
param. See config for more on the topic.
For build steps that are not platform-specific, such as compiling
CoffeeScript or other languages to JavaScript, use the prepare script
to
do this, and make the required package a devDependency.
For example:
{
"name": "ethopia-waza",
"description": "a delightfully fruity coffee varietal",
"version": "1.2.3",
"devDependencies": {
"coffee-script": "~1.6.3"
},
"scripts": {
"prepare": "coffee -o lib/ -c src/waza.coffee"
},
"main": "lib/waza.js"
}
The prepare script will be run before publishing, so that users can
consume the functionality without requiring them to compile it them-
selves.
In dev mode (ie, locally running npm install), it'll run this script as
well, so that you can test it easily.
peerDependencies
In some cases, you want to express the compatibility of your package
with a
host tool or library, while not necessarily doing a require of this
host.
This is usually referred to as a plugin. Notably, your module may be
exposing a specific interface, expected and specified by the host
documentation.
For example:
{
"name": "tea-latte",
"version": "1.3.5",
"peerDependencies": {
"tea": "2.x"
}
}
This ensures your package tea-latte can be installed along with the
second major version of the host package tea only. npm install
tea-latte could possibly yield the following dependency graph:
├── tea-latte@1.3.5
└── tea@2.2.0
In npm versions 3 through 6, peerDependencies were not automatically
installed, and would raise a warning if an invalid version of the peer
dependency was found in the tree. As of npm v7, peerDependencies are
installed by default.
Trying to install another plugin with a conflicting requirement may
cause
an error if the tree cannot be resolved correctly. For this reason,
make
sure your plugin requirement is as broad as possible, and not to lock
it
down to specific patch versions.
Assuming the host complies with semver, only changes
in the host package's major version will break your plugin. Thus, if
you've
worked with every 1.x version of the host package, use "^1.0"
or "1.x"
to express this. If you depend on features introduced in 1.5.2, use
"^1.5.2".
peerDependenciesMeta
When a user installs your package, npm will emit warnings if packages
specified in peerDependencies are not already installed. The
peerDependenciesMeta field serves to provide npm more information on
how
your peer dependencies are to be used. Specifically, it allows peer
dependencies to be marked as optional.
For example:
{
"name": "tea-latte",
"version": "1.3.5",
"peerDependencies": {
"tea": "2.x",
"soy-milk": "1.2"
},
"peerDependenciesMeta": {
"soy-milk": {
"optional": true
}
}
}
Marking a peer dependency as optional ensures npm will not emit a warn-
ing
if the soy-milk package is not installed on the host. This allows you
to
integrate and interact with a variety of host packages without requir-
ing
all of them to be installed.
bundleDependencies
This defines an array of package names that will be bundled when pub-
lishing
the package.
In cases where you need to preserve npm packages locally or have them
available through a single file download, you can bundle the packages
in a
tarball file by specifying the package names in the bundleDependencies
array and executing npm pack.
For example:
If we define a package.json like this:
{
"name": "awesome-web-framework",
"version": "1.0.0",
"bundleDependencies": [
"renderized",
"super-streams"
]
}
we can obtain awesome-web-framework-1.0.0.tgz file by running npm pack.
This file contains the dependencies renderized and super-streams which
can be installed in a new project by executing npm install awe-
some-web-framework-1.0.0.tgz. Note that the package names do not
include any versions, as that information is specified in dependencies.
If this is spelled "bundledDependencies", then that is also
honored.
Alternatively, "bundleDependencies" can be defined as a bool-
ean value. A
value of true will bundle all dependencies, a value of false will bun-
dle
none.
optionalDependencies
If a dependency can be used, but you would like npm to proceed if it
cannot
be found or fails to install, then you may put it in the
optionalDependencies object. This is a map of package name to version
or
url, just like the dependencies object. The difference is that build
failures do not cause installation to fail. Running npm install
--omit=optional will prevent these dependencies from being installed.
It is still your program's responsibility to handle the lack of the
dependency. For example, something like this:
try {
var foo = require('foo')
var fooVersion = require('foo/package.json').version
} catch (er) {
foo = null
}
if ( notGoodFooVersion(fooVersion) ) {
foo = null
}
// .. then later in your program ..
if (foo) {
foo.doFooThings()
}
Entries in optionalDependencies will override entries of the same name
in
dependencies, so it's usually best to only put in one place.
overrides
If you need to make specific changes to dependencies of your dependen-
cies, for
example replacing the version of a dependency with a known security is-
sue,
replacing an existing dependency with a fork, or making sure that the
same
version of a package is used everywhere, then you may add an override.
Overrides provide a way to replace a package in your dependency tree
with
another version, or another package entirely. These changes can be
scoped as
specific or as vague as desired.
To make sure the package foo is always installed as version 1.0.0 no
matter
what version your dependencies rely on:
{
"overrides": {
"foo": "1.0.0"
}
}
The above is a short hand notation, the full object form can be used to
allow
overriding a package itself as well as a child of the package. This
will cause
foo to always be 1.0.0 while also making bar at any depth beyond foo
also 1.0.0:
{
"overrides": {
"foo": {
".": "1.0.0",
"bar": "1.0.0"
}
}
}
To only override foo to be 1.0.0 when it's a child (or grandchild, or
great
grandchild, etc) of the package bar:
{
"overrides": {
"bar": {
"foo": "1.0.0"
}
}
}
Keys can be nested to any arbitrary length. To override foo only when
it's a
child of bar and only when bar is a child of baz:
{
"overrides": {
"baz": {
"bar": {
"foo": "1.0.0"
}
}
}
}
The key of an override can also include a version, or range of ver-
sions.
To override foo to 1.0.0, but only when it's a child of bar@2.0.0:
{
"overrides": {
"bar@2.0.0": {
"foo": "1.0.0"
}
}
}
You may not set an override for a package that you directly depend on
unless
both the dependency and the override itself share the exact same spec.
To make
this limitation easier to deal with, overrides may also be defined as a
reference to a spec for a direct dependency by prefixing the name of
the
package you wish the version to match with a $.
{
"dependencies": {
"foo": "^1.0.0"
},
"overrides": {
// BAD, will throw an EOVERRIDE error
// "foo": "^2.0.0"
// GOOD, specs match so override is allowed
// "foo": "^1.0.0"
// BEST, the override is defined as a reference to the dependency
"foo": "$foo",
// the referenced package does not need to match the overridden one
"bar": "$foo"
}
}
engines
You can specify the version of node that your stuff works on:
{
"engines": {
"node": ">=0.10.3 <15"
}
}
And, like with dependencies, if you don't specify the version (or if
you
specify "*" as the version), then any version of node will do.
You can also use the "engines" field to specify which versions of npm
are
capable of properly installing your program. For example:
{
"engines": {
"npm": "~1.0.20"
}
}
Unless the user has set the
engine-strict config flag, this field is
advisory only and will only produce warnings when your package is in-
stalled as a
dependency.
os
You can specify which operating systems your
module will run on:
{
"os": [
"darwin",
"linux"
]
}
You can also block instead of allowing operating systems, just prepend
the
blocked os with a '!':
{
"os": [
"!win32"
]
}
The host operating system is determined by process.platform
It is allowed to both block and allow an item, although there isn't any
good reason to do this.
cpu
If your code only runs on certain cpu architectures,
you can specify which ones.
{
"cpu": [
"x64",
"ia32"
]
}
Like the os option, you can also block architectures:
{
"cpu": [
"!arm",
"!mips"
]
}
The host architecture is determined by process.arch
private
If you set "private": true in your package.json, then npm
will refuse to
publish it.
This is a way to prevent accidental publication of private reposito-
ries.
If you would like to ensure that a given package is only ever published
to
a specific registry (for example, an internal registry), then use the
publishConfig dictionary described below to override the registry
config param at publish-time.
publishConfig
This is a set of config values that will be used at publish-time. It's
especially handy if you want to set the tag, registry or access, so
that
you can ensure that a given package is not tagged with "latest", pub-
lished
to the global public registry or that a scoped module is private by
default.
See config to see the list of config options that
can be overridden.
workspaces
The optional workspaces field is an array of file patterns that de-
scribes
locations within the local file system that the install client should
look
up to find each workspace that needs to be
symlinked to the top level node_modules folder.
It can describe either the direct paths of the folders to be used as
workspaces or it can define globs that will resolve to these same fold-
ers.
In the following example, all folders located inside the folder
./packages will be treated as workspaces as long as they have valid
package.json files inside them:
{
"name": "workspace-example",
"workspaces": [
"./packages/*"
]
}
See workspaces for more examples.
DEFAULT VALUES
npm will default some values based on package contents.
• "scripts": {"start": "node server.js"}
If there is a server.js file in the root of your package, then npm
will
default the start command to node server.js.
• "scripts":{"install": "node-gyp re-
build"}
If there is a binding.gyp file in the root of your package and you
have
not defined an install or preinstall script, npm will default the
install command to compile using node-gyp.
• "contributors": [...]
If there is an AUTHORS file in the root of your package, npm will
treat
each line as a Name <email> (url) format, where email and url are
optional. Lines which start with a # or are blank, will be ignored.
