If you have an app in subversion with many externals, it may take a bit too long to update it, as updates happen one after another. This gem updates the root and each external in parallel, making it much faster.
NOTES: After adding/changing externals or external properties, you'll need to run the standard svn up
once before running this script again
Original Script From: kch on http://codesnippets.joyent.com/posts/show/548
Add this line to your application's Gemfile:
gem 'svn_parallel', :git => 'git://github.com/tleish/svn_parallel.git'
And then execute:
$ bundle install
Or install it yourself as:
$ git clone git://github.com/tleish/svn_parallel.git
$ git clone https://github.com/tleish/svn_parallel.git
$ cd svn_parallel
$ gem install svn_parallel
$ cd <svn root directory...>
$ svnup
