Stickler is a tool to organize and maintain an internal gem repository. At times it is useful to have complete control over the availability of the gems for you testing, staging and production environments. In these cases you probably do not want to accidentally type 'gem update' and get a new untested version of a gem installed on your machines. This is where Stickler helps. Configure stickler with the the names and versions of the gems you require for your deployment and it will organize and setup everything that is necessary for a standard web server to function as your internal gem distribution server.
