@moduledoc """
Drop the storage for the given repository.
The repositories to drop are the ones specified under the
`:ecto_repos` option in the current app configuration. However,
if the `-r` option is given, it replaces the `:ecto_repos` config.
Since Ecto tasks can only be executed once, if you need to drop
multiple repositories, set `:ecto_repos` accordingly or pass the `-r`
flag multiple times.
## Examples
mix ecto.drop
mix ecto.drop -r Custom.Repo
## Command line options
* `--no-compile` - do not compile before stopping
* `-r`, `--repo` - the repo to drop
* `-q`, `--quiet` - run the command quietly
* `-f`, `--force` - do not ask for confirmation when dropping the database.
Configuration is asked only when `:start_permanent` is set to true
(typically in production)
