<<<EOT
Use this command as a wrapper to run other Composer commands
within the global context of COMPOSER_HOME.
You can use this to install CLI utilities globally, all you need
is to add the COMPOSER_HOME/vendor/bin dir to your PATH env var.
COMPOSER_HOME is c:\Users\<user>\AppData\Roaming\Composer on Windows
and /home/<user>/.composer on unix systems.
If your system uses freedesktop.org standards, then it will first check
XDG_CONFIG_HOME or default to /home/<user>/.config/composer
Note: This path may vary depending on customizations to bin-dir in
composer.json or the environmental variable COMPOSER_BIN_DIR.
