[development] Any Drupal Tools for Automating Staging Site Creation?

[Mike Cantelon]

Hi all,

Has anyone created any tools for automating site setup?

Basically what I'm doing now each night via a script is:
1) Cloning my production site
2) Replacing certain directories with versions checked out from Subversion
3) Running a series of Linux commands and SQL queries to set up modules 
that are in development but have not been deployed to production

Whenever I start development on a new module I have to add to my 
mirroring script to automate Drupal setup. I can write some PHP 
functions to encapsulate this, but maybe something already exists?

Cheers,
Mike
