Dbup, a simple PHP migration tool

Dbup is a simple migration tool for PHP.

• You have only to download dbup.phar.
• Dbup has only up command. Dbup does not have down command.
• Dbup use just a plain old sql, so you don't have to learn ORM nor DSL. You write sql file and just call up command.
• Dbup use just PDO class to migrate.
• Dbup doesn't need the table in a database to migrate.

Applied migration sql files are copied to .dbup/applied directory. If a same file exists both sql and .dbup/applied directory, up command ignores this sql file.

user = "%%DBUP_USERNAME%%"
