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

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>

You can add a repository to 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>
