Heroku fork -a (what's -a?)

Getting familiar with heroku fork syntax: heroku fork -a sourceapp targetapp

So I attempt to RTM:

$ heroku help fork
Usage: heroku fork [NEWNAME]

 Fork an existing app -- copy config vars and Heroku Postgres data, and re-provision add-ons to a new app.
 New app name should not be an existing app. The new app will be created as part of the forking process.

 -s, --stack  STACK   # specify a stack for the new app
 --region REGION      # specify a region

No mention of -a flag. What does this do? Is it always required?

As of May 14, 2015 heroku fork now expects --from and --to arguments. The new documentation is much clearer.

heroku fork --from APP_TO_FORK_FROM --to APP_TO_CREATE

Original and now wrong answer with deprecated options for older version of the Heroku toolbelt:

For all heroku commands, -a or --app is the app that you you want the command to affect. The previous documentation for fork described it thusly:

heroku fork -a sourceapp targetapp

Without the '-a' flag it infers the app from the current directory or fail and ask you to specify and app or run it from an app directory.

This has changed, now the CLI expects --from and --to instead of --app.
