Building a simplified RCS.

[Rajorshi Ghosh Choudhury]

 I have been using RCS regularly for a few months now. I know the basic 
RCS commands and have a vague idea about rcs library files (which is 
knowing nothing more than that they exist). Now I have been asked to 
create a "simplified version control for a single user" as part of my 
semester project. I am totally lost. Can someone please tell me how to go 
about it.
    References to sites which offer a general overview of the topic as 
well as show the "dirty" details of implementing such a system would be 
very welcome too.
    Thanks in advance.
                                Rajorshi.
