cfvers is a versioning system for configuration files. It is similar
to cvs and subversion, but different in its orientation toward system
configuration files (think /etc), dealing with all file types and
attributes.

Features:
  - does not pollute the filesystem outside its dirs;
  - keeps both data and metadata (owner, group, perms, atime,
    mtime);
  - deals with all types of files (S_IFSOCK, S_IFLNK, S_IFREG,
    S_IFBLK, S_IFDIR, S_IFCHR, S_IFIFO);

Current working backends are sqlite and postgresql.

Warning: cfvers is in alpha state; don't trust your data to it
(yet!). Also the interfaces, repositories, etc. can and will change
before beta.
