The ultimate goal was to create a tool that will allow you to solve the described problem quickly and reliably. When writing the code, the emphasis was on minimal configuration, thread safety, and ease of use. Sources are available on gitachba and the gem itself is available on rubygems. If for someone this gem will be useful and there are ideas and a desire to improve / fix it, I will gladly accept PR or comments) Thank you all who have read to the end!
