title: Database schema migration
body: <p>Before I reinvent the wheel is there a simple tool out there that does schema migration similar to laravel but using standard SQL?</p>
  
  <p>Many schema migration tools just apply migration files based on the numeric prefix where said prefix is greater than the current table increment.</p>
  
  <p>I'm more interested in a tool that loops through all the files in a migration directory in order (numeric prefix) and applies any MISSING (from the databases migration table) sql migration files to the database.</p>
  
  <p>Prefer FOSS and wouldn't kick rollback functionality out of bed either.</p>
