Description:

SQLite is a light weight single file SQL database that provides an
excellent platform for embedded storage of structured data.

ORLite is a light weight single class Object-Relational Mapper (ORM)
system specifically designed for (and limited to only) work with SQLite.

ORLite::Migrate is a light weight single class Database Schema Migration
enhancement for ORLite.

It provides a simple implementation of schema versioning within the
SQLite database using the built-in user_version pragma (which is set to
zero by default).

When setting up the ORM class, an additional timeline parameter is
provided, which should point to a directory containing standalone
migration scripts.
