class Tlf\LilMigrations

A minimal class for handling sql migration. Create a migrations dir. Then create dirs like v1, v2 & create files up.sql, down.sql in each versioned dir. Migrating from 1 to 2 will execute v2/up.sql. From 3 down to 1 will execute v2/down.sql and v1/down.sql. You may also make files like v1/up-1.sql, v1/up-2.sql to execute multiple files in order.
