# `mix mailglass.gen.migration`
[🔗](https://github.com/szTheory/mailglass/blob/v0.1.0/lib/mix/tasks/mailglass.gen.migration.ex#L1)

Generates the 8-line wrapper migration file in `priv/repo/migrations/`
that delegates `up/0` and `down/0` to `Mailglass.Migration`.

Run after `mix mailglass.install` if the wrapper is missing; idempotent.
