The <info>reinstall</info> command looks up installed packages by name,
uninstalls them and reinstalls them. This lets you do a clean install
of a package if you messed with its files, or if you wish to change
the installation type using --prefer-install.

<info>php composer.phar reinstall acme/foo "acme/bar-*"</info>
