+  Create the storage for the given repository.
+
+  The repositories to create 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 create
+  multiple repositories, set `:ecto_repos` accordingly or pass the `-r`
+  flag multiple times.
+
+  ## Examples
+
+      $ mix ecto.create
+      $ mix ecto.create -r Custom.Repo
+
+  ## Command line options
+
+    * `-r`, `--repo` - the repo to create
+    * `--quiet` - do not log output
+    * `--no-compile` - do not compile before creating
+    * `--no-deps-check` - do not compile before creating
