I've been putting off setting up multisite on my localhost for ages, mostly because in the past I've found getting Apache virtual hosts to work can be a bit tricky: not impossible, but the sort of thing where I could easily lose an hour on a minor thing I've forgotten to do. And after all, with a shiny new iMac and a hard drive whose proportions I can't even remember, why not just 'drush dl' all over again?

But I'm actually working on a multisite project at the moment, and suddenly getting this to work becomes more interesting than having another SVN copy of my code kicking around.

Given multisite can respond to subfolders, I was wondering if this could work when Drupal itself is in a subfolder, like this:

Okay, so I lied. But module builder can save you a lot of time when writing custom modules.

And it now works with drush, too. I added support for drush a few weeks ago, which let you do things like "$ drush mb mymodule cron init menu nodeapi --write" and hey presto, a new module folder is created, with an info file and a module file, with hook implementations ready to do your (evil) bidding. (Note: this blog does not sanction use of Drupal, module builder, or drush for evil.)
