This command allows you to edit some basic composer settings in either the

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 http://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
package into a new directory. If executed without params and in a directory
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.

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-url=http://myrepository.org'</info> flag.
