dalin's sandbox: Site Clone

Drush command to clone a site:

1. Copies the codebase (excluding the files directory) with rsync to a new location.
2. Creates a new git branch (optional).
3. Creates a new /sites directory and settings.php file.
4. Creates a new files directory.
5. Copies the database.
6. Writes database connection info to a global config file.

It also does thorough validation on the input parameters (about 20 different validations for everything from checking that the destination directory is writable, to ensuring that the name of the new database is valid).

There's some things here that are specific to Advomatic and Cadre hosting environments. But things can probably be generalized without too much effort.

Here's an example of how it's run:

drush advo-site-clone --destination-domain=test.cf.local --destination-db-name=test --git-branch=test
