What's this?

use_gemdeps() public

Looks for gem dependency files (gem.deps.rb, Gemfile, Isolate) from the current directory up and activates the gems in the first file found.

You can run this automatically when rubygems starts. To enable, set the RUBYGEMS_GEMDEPS environment variable to either the path of your Gemfile or “-” to auto-discover in parent directories.

NOTE: Enabling automatic discovery on multiuser systems can lead to execution of arbitrary code when used from directories outside your control.
