The <info>%command.name%</info> command installs bundle assets into a given

A "bundles" directory will be created inside the target directory and the
"Resources/public" directory of each bundle will be copied into it.

To create a symlink to each bundle instead of copying its assets, use the
<info>--symlink</info> option (will fall back to hard copies when symbolic links aren't possible:

  <info>php %command.full_name% public --symlink</info>

To make symlink relative, add the <info>--relative</info> option:

  <info>php %command.full_name% public --symlink --relative</info>
