Thank you. What I now see is that RCS is mostly good for software
projects that are able to use `make`, and that have a flat directory
structure. That includes projects written in C. Now I wonder about
projects that don't use Makefiles. For example, Python and Java
software, or even just a collection of txt files. I suppose RCS is
completely unsuitable for use in Java projects because of its directory
structure requirements (e.g. src/com/example/).
