Maybe Concurrent Versions System
Or a drugstore
not so bad ozo, both may be true :-))

beside other interpretations, CVS (see ozo's comment) is a tool to manage versions of files by deltas. It's based on rcs, but has a GUI too.

You can have this one (if you answer again), but can you be more specific this time. deltas????? rcs??????? you've confused me even more.

If you make changes to a file, the diff(erence) between the old and new version of the file (respectively before and after editing) is called a delta (in terms when speaking about version control).

rcs is an acronym for Revision control system, which is a set of commands to put files and their changes (deltas) under control of a sytem which allows you to rebuild any version of a file.

So far for the points ;-)

Some more:
1. acronyms
      SCCS      Source Code Control System
            the ancestor of all those systems (I think), normaly delivered with all Unixs (except Linux and SCO)

      RCS      Revision Control System
            the public domain version (gnu) of SCCS, has less or more features (depends on your private mind)

      CVS      Concurent Version System
            sophisticated frontend to RCS

      some comercial systems exist too


2. what's the goal of all these systems?

      Once you have a file where you want to record all changes and access a ancient version in future, you may need it. You also may make (backup)copys of each version of your file, then you don't need it.
      If a file is under control of such a system you easyly may check the difference (delta) between several versions, or rebuild a former version which was stored.

      The trick is, that these systems do not copy the files, but only save the changes (deltas) in a special mannor.

Thanks for bearing with me on this, and thanks for the detailed answer which deserves more points than I give you credit for.

I'm happy to give you an "A".

Well there should be no problem to hand over more points ;-))

If you need more info (I'm specialised on SCCS), ask a new question.
