Gem in a box is a simple sinatra app to allow you to host your own in-house gems.
It has no security, or authentication so you should handle this yourself.
gem install geminabox
Create a config.ru as follows:
require "rubygems" require "geminabox" Geminabox.data = "/var/geminabox-data" # …or wherever run Geminabox
gem install geminabox gem inabox pkg/my-awesome-gem-1.0.gem
Fork it, mod it, choose it, use it, make it better. All under the do what the fuck you want to + beer/pizza public license.
