ruby script/plugin install http://custommigrator.rubyforge.org/svn/plugins/custom_migrator/

The custom migrator uses a different scheme for db rails migrations. It deals with three artifacts, 1) migration_list.yml, 2) migrations_bookmark table in the database, and 3) migration files.

migration_list.yml
===================

It maintains a master list file called migration_list.yml which contains an ordered list of migration file names. For example, for the contents in db/migration directory db/migration

		* create_user.rb
		* create_account.rb
		* create_employee.rb
		* migration_list.yml

contents of migration_list.yml

			- create_user.rb
			- create_account.rb
			- create_employee.rb

The order is based on the sequence of migrations creation using ruby script/generation migration [migrationName] command.

migrations_bookmark table
===================
This is the table automatically created (if not present already) before running migrations. This contains one column called book_mark and at any point of time it will have 0 or 1 rows. The value will be file name of a migration.

migrations
===================
These are similar to the standard rails migration files, but don't contain numbers or timestamps in the file names.

There is currently no advanced documentation for this plugin.
