What is this project all about? This project ist primarily for my custom ruby-related stuff. I have no idea if anyone else may need this or could find anything in it useful, but in case that someone may find something useful here, here we go. When I am before a new computer, and a ruby is available on that machine (or I can compile it), then this is the gem that I will install first, usually (together with the colour-related gems). It is thus sort of like my "basic working tools", code that I can use daily. I also needed this gem available so that I can install it on other computers as well, as I am not always working at home. It has only a very few external dependencies. Some are within the distinct .rb files but usually protected via a begin/rescue LoadError clause. Presently this project has only a very few dependencies but in theory, all external dependencies could be removed altogether. Since as of March 2018, this project also includes a slightly modified version of setup.rb - I needed it available in the event that an installation via gems would fail.
