The [generate:app|INFO] task creates the basic directory structure
for a new application in the current project:

  [./symfony generate:app frontend|INFO]

This task also creates two front controller scripts in the
[web/|COMMENT] directory:

  [web/%application%.php|INFO]     for the production environment
  [web/%application%_dev.php|INFO] for the development environment

For the first application, the production environment script is named
[index.php|COMMENT].

If an application with the same name already exists,
it throws a [sfCommandException|COMMENT].

You can enable output escaping (to prevent XSS) by using the [escaping-strategy|COMMENT] option:

  [./symfony generate:app frontend --escaping-strategy=on|INFO]

You can enable session token in forms (to prevent CSRF) by defining
a secret with the [csrf-secret|COMMENT] option:

  [./symfony generate:app frontend --csrf-secret=UniqueSecret|INFO]
