This command allows you to edit some basic composer settings in either the
local composer.json file or the global config.json file.

To set a config setting:

    <comment>%command.full_name% bin-dir bin/</comment>

To read a config setting:

    <comment>%command.full_name% bin-dir</comment>
    Outputs: <info>bin</info>

To edit the global config.json file:

    <comment>%command.full_name% --global</comment>

To add a repository:

    <comment>%command.full_name% repositories.foo vcs https://bar.com</comment>

To remove a repository (repo is a short alias for repositories):

    <comment>%command.full_name% --unset repo.foo</comment>

To disable packagist:

    <comment>%command.full_name% repo.packagist false</comment>

You can alter repositories in the global config.json file by passing in the
<info>--global</info> option.

To edit the file in an external editor:

    <comment>%command.full_name% --editor</comment>

To choose your editor you can set the "EDITOR" env variable.

To get a list of configuration values in the file:

    <comment>%command.full_name% --list</comment>

You can always pass more than one option. As an example, if you want to edit the
global config.json file.

    <comment>%command.full_name% --editor --global</comment>

The <info>create-project</info> command creates a new project from a given

with a composer.json file it installs the packages for the current project.

You can use this command to bootstrap new projects or setup a clean
version-controlled installation for developers of your project.

<info>php composer.phar create-project vendor/project target-directory [version]</info>

You can also specify the version with the package name using = or : as separator.

<info>php composer.phar create-project vendor/project:version target-directory</info>

To install unstable packages, either specify the version you want, or use the
--stability=dev (where dev can be one of RC, beta, alpha or dev).

To setup a developer workable version you should create the project using the source
controlled code by appending the <info>'--prefer-source'</info> flag.

To install a package from another repository than the default one you
can pass the <info>'--repository=https://myrepository.org'</info> flag.

## Bundle of CA Root Certificates

## Certificate data from Mozilla as of: Wed Jan 20 04:12:04 2016
##
## This is a bundle of X.509 certificates of public Certificate Authorities

## file (certdata.txt).  This file can be found in the mozilla source tree:
## http://hg.mozilla.org/releases/mozilla-release/raw-file/default/security/nss/lib/ckfw/builtins/certdata.txt
##
## It contains the certificates in PEM format and therefore
## can be directly used with curl / libcurl / php_curl, or with
## an Apache+mod_ssl webserver for SSL client authentication.
## Just configure this file as the SSLCACertificateFile.

## Conversion done with mk-ca-bundle.pl version 1.25.
