<<<EOT
This command allows you to edit composer config settings and repositories
in either the local composer.json file or the global config.json file.

Additionally it lets you edit most properties in the local composer.json.

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 add or edit suggested packages you can use:

<comment>%command.full_name% suggest.package reason for the suggestion</comment>

To add or edit extra properties you can use:

<comment>%command.full_name% extra.property value</comment>

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>

<<<EOT
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.

<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.
