from cvs to subversion

Subversion was written by the maintainers of CVS and is the upcoming alternative to CVS. Over the years CVS has become the de-facto standard of source code management systems.

But CVS has also grown old:

• CVS does not keep track of renaming files and directories.
  When you rename a file it is just recorded as one file deleted and another file being added.

• CVS does not provide information which files were part of a single commit.
  This is a nasty thing when one wants to revert a single commit done some days ago. Dealing with such issues in CVS means to add tags in advance or to create diffs for every commit.
