    This is byteman's install library copied, with small modifications. This is done with permission of Andrew Dinn, author of Byteman. For the original source of this code, please follow links below: http://byteman.jboss.org/ -- official page https://github.com/bytemanproject/byteman -- git repository This is a provisional solution for the attach, while I am trying to create an abstract library to share some functionality.
