Considering I just found out about this project a few days ago, I will assume that some may not be familiar with Sparks. Sparks is a new command line tool for CodeIgniter. For those familiar with Drush for drupal this seems very similar except not quite as complex. Sparks basically takes all of the leg work out of installing third party add-ons to CI. With a single command you can install libraries and have them ready to use.
If you haven't already I suggest going to http://getsparks.org/ and checking out the sparks that are available. Also if you have some good libraries consider porting those to sparks so that others can enjoy them. I have created sparks for both the youtube and dropbox api libraries. Once you have sparks installed it will be as simple as installing the youtube or dropbox spark then loading the spark and loading the library.
I would really like to see this project get even more notoriety than it already has so check out sparks.
