Multiple Symfony versions in the same environment
I've been using this trick from symfonynerds to run multiple Symfony versions in the same environments. I can now work on projects built on Symfony 1.0, 1.1, and 1.2 simultaneously in the same environment (Ubuntu 8.10).
So now, when I want to create a Symfony 1.0 project, I would just execute "$ symfony10 init-project myproject". And then in the project I would use "$ ./symfony cc" instead of "$ symfony cc".
It worths mentioning that I think this trick is good for development environment but "svn:externals" trick or Symfony freeze are better for production/deployment as each project will have their own copy of Symfony Framework.
